Biographical information with respect to Mr. Kurnit is contained in About's annual report on Form 10-K for the year ended December 31, 1999 and About's proxy statement for its 2000 annual meeting of stockholders dated April 10, 2000, and is incorporated herein by reference.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

In the opinion of Simpson Thacher & Bartlett, special tax counsel to PRIMEDIA, and Brobeck, Phleger & Harrison LLP, special tax counsel to About, the following discussion summarizes the material United States federal income tax consequences of the merger that will generally apply to U.S. holders of About stock.

For purposes of this discussion, a U.S. holder means:

- an individual citizen or resident of the United States;

- a corporation or other entity taxable as a corporation created or organized under the laws of the United States or any of its political subdivisions;

- a trust, if a U.S. court is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust; or

- an estate that is subject to United States federal income tax on its income regardless of its source.

This discussion does not address any tax consequences arising under the laws of any state, locality or foreign jurisdiction. This discussion is not a comprehensive description of all of the tax consequences that may be relevant to you. For example, we have not described tax consequences that arise from rules that apply to some classes of taxpayers. We have also not described tax consequences that we assume to be generally known by investors. This discussion is based upon the Internal Revenue Code of 1986, as amended (the "Code"), the regulations of the United States Treasury Department and court and administrative rulings and judicial decisions in effect on the date of this prospectus. These laws may change, possibly retroactively, and any change could affect the continuing validity of this discussion.

This discussion assumes that you hold your shares of About stock as a capital asset and does not address the tax consequences that may be relevant to you in light of your particular circumstances. In addition, it does not present a description of the United States federal income tax laws applicable to you if you are subject to special treatment under the United States federal income tax laws, including if you are:

- a financial institution;

- a tax-exempt organization;

- an S corporation or other pass-through entity;

- an insurance company;

- a dealer in securities or foreign currencies;

- a trader in securities that elects the mark-to-market method of accounting for your securities;

63

- a person that has a functional currency other than the U.S. dollar;

- an investor in a pass-through entity;

- an About stockholder who received your About stock through the exercise of employee stock options or otherwise as compensation;

- an About stockholder who holds About stock as part of a hedge, straddle or conversion transaction; or

- a person subject to the alternative minimum tax provisions of the Code.

The summary that follows sets out the material United States federal income tax consequences to U.S. holders who exchange their About stock for PRIMEDIA common stock. As a condition to the closing, Simpson Thacher & Bartlett, tax counsel to PRIMEDIA, and Brobeck, Phleger & Harrison LLP, tax counsel to About, must render tax opinions that the merger will constitute a reorganization with the meaning of Section 368(a) of the Code. The opinions of counsel will be based upon (i) certain factual representations made by PRIMEDIA, About and Abracadabra Acquisition Corporation, and (ii) the assumption that the transactions described herein will be consummated in accordance with the terms of the merger agreement and related agreements. PRIMEDIA and About will not seek a ruling from the Internal Revenue Service concerning the tax consequences of the transactions described herein. An opinion of counsel is not binding on the Internal Revenue Service and we can give no assurance that the Internal Revenue Service will not take a position contrary to one or more positions reflected in the opinions or that the courts will uphold such opinions if challenged by the Internal Revenue Service.

If the merger qualifies as a reorganization:

- you will not recognize gain or loss when you exchange your About stock solely for PRIMEDIA common stock;

- if you receive cash instead of a fractional share of PRIMEDIA common stock you will be treated as having received the cash in exchange for the fractional share interest and generally will recognize capital gain or loss on the deemed exchange in an amount equal to the difference between the amount of cash received and the basis of the About stock allocable to that fractional share;

- the aggregate tax basis of PRIMEDIA common stock you receive will be the same as the aggregate tax basis of the About stock you surrender in the exchange, decreased by the tax basis allocated to any fractional share interest exchanged for cash; and

- the holding period of PRIMEDIA common stock you receive will include the holding period of shares of About stock you surrender in the exchange.

BACKUP WITHHOLDING. If you are a noncorporate holder of About stock you may be subject to backup withholding at a 31% rate on any cash payments received in lieu of a fractional share interest in About stock. You will not be subject to backup withholding, however, if you:

- furnish a correct taxpayer identification number and certify that you are not subject to backup withholding on the substitute Form W-9 or successor form included in the letter of transmittal to be delivered to you following the completion of the merger;

- provide a certification of foreign status on Form W-8 or a successor form; or

- are otherwise exempt from backup withholding.

64

Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against your United States federal income tax liability, provided you furnish the required information to the Internal Revenue Service.

REPORTING REQUIREMENTS. You may be required to retain records relating to your About stock, and file with your U.S. federal income tax return a statement setting forth facts relating to the merger.

TAX MATTERS ARE VERY COMPLICATED, AND THE TAX CONSEQUENCES OF THE MERGER TO YOU WILL DEPEND UPON THE FACTS OF YOUR PARTICULAR SITUATION. WE ENCOURAGE YOU TO CONSULT YOUR OWN TAX ADVISORS REGARDING THE SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING TAX RETURN REPORTING REQUIREMENTS, THE APPLICABILITY OF FEDERAL, STATE, LOCAL AND FOREIGN TAX LAWS AND THE EFFECT OF ANY PROPOSED CHANGE IN THE TAX LAWS.

ACCOUNTING TREATMENT OF THE MERGER

PRIMEDIA intends to account for the merger as the accounting acquiror in a purchase business combination for financial reporting and accounting purposes, under generally accepted accounting principles. After the merger, the results of operations of About will be included in the consolidated financial statements of PRIMEDIA.

REGULATORY APPROVALS

HART-SCOTT-RODINO.

Effective November 9, 2000, PRIMEDIA and About filed their respective Pre-Merger Notification and Report Forms with the Federal Trade Commission or the Department of Justice under the Hart-Scott-Rodino Act. The companies were notified on November 22, 2000 that early termination of the waiting period was granted. The Antitrust Division of the Department of Justice and the Federal Trade Commission, as well as a state antitrust authority or private person, may challenge the merger at any time before or after the merger is completed.

OTHER APPROVALS. In addition, the merger will require certain notices to be filed in Delaware and notices or approvals in certain of the other states where PRIMEDIA and About are engaged in business.

The approval of an application means only that the regulatory criteria for approval have been satisfied or waived. It does not mean that the approving authority has determined that the consideration to be received by About stockholders is fair. Regulatory approval does not constitute an endorsement or recommendation of the merger.

EXCHANGE OF ABOUT STOCK CERTIFICATES

When the merger is completed, if you are an About stockholder, the exchange agent will mail to you a letter of transmittal and instructions for use in surrendering your About stock certificates in exchange for statements indicating book-entry ownership of PRIMEDIA stock or, if requested, stock certificates. When you deliver your stock certificates to the exchange agent along with a properly executed letter of transmittal and any other required documents, your stock certificates will be canceled and you will receive statements indicating book-entry ownership of PRIMEDIA common stock or, if requested, stock certificates representing the number of full shares of PRIMEDIA stock to which you are entitled under the merger agreement. About stockholders will receive payment in cash, without interest, instead of any fractional shares of PRIMEDIA common stock that would have been otherwise issuable to them as a result of the merger. The amount of cash payable to any About stockholder will be an amount equal to the product of any fractional share of PRIMEDIA common stock which the holder would have been entitled to receive MULTIPLIED BY the closing price on the New York Stock Exchange for a share of PRIMEDIA common stock as reported by The Wall Street Journal on the closing date of the merger, rounded down to the nearest cent.

65

YOU SHOULD NOT SUBMIT YOUR ABOUT STOCK CERTIFICATES FOR EXCHANGE UNTIL YOU RECEIVE THE TRANSMITTAL INSTRUCTIONS AND A FORM OF LETTER OF TRANSMITTAL FROM THE EXCHANGE AGENT.

You are not entitled to receive any dividends or other distributions on PRIMEDIA stock until the merger is completed and you have surrendered your About stock certificates in exchange for PRIMEDIA stock certificates.

If there is any dividend or other distribution on PRIMEDIA stock with a record date after the date on which the merger is completed and a payment date prior to the date you surrender your About stock certificates in exchange for PRIMEDIA stock certificates, you will receive the dividend or distribution, without interest, with respect to the whole shares of PRIMEDIA stock issued to you promptly after they are issued. If there is any dividend or other distribution on PRIMEDIA stock with a record date after the date on which the merger is completed and a payment date after the date you surrender your About stock certificates in exchange for PRIMEDIA stock certificates, you will receive the dividend or distribution, without interest, with respect to the whole shares of PRIMEDIA stock issued to you promptly after the payment date.

PRIMEDIA will only issue PRIMEDIA shares or cash instead of a fractional share in a name other than the name in which a surrendered About stock certificate is registered if you present the exchange agent with all documents required to show and effect the unrecorded transfer of ownership and show that you paid any applicable stock transfer taxes.

TREATMENT OF STOCK OPTIONS AND OTHER RIGHTS

When the merger is completed, PRIMEDIA will assume each outstanding About employee stock option and each option will be deemed to constitute an option to acquire a number of shares of PRIMEDIA common stock equal to the number of shares of About subject to the option multiplied by the exchange ratio, rounded down if necessary to the nearest whole share. The exercise price per share for the assumed options will be the exercise price per share under the About stock options divided by the exchange ratio, rounded down to the nearest cent. If an employee of About is involuntarily terminated or voluntarily terminates for a permitted reason within 12 months of the merger, the employee's unvested stock options become vested and exercisable. The other material terms of all assumed About options referred to above will continue to apply.

If necessary, PRIMEDIA will file a registration statement covering the issuance of the shares of PRIMEDIA common stock subject to each converted About option and will maintain the effectiveness of that registration statement for as long as any of the options remain outstanding.

Immediately prior to the effective time of the merger, the vesting schedule for options granted to the directors of About (other than Mr. Kurnit) under the Automatic Option Grant Program under About's Amended and Restated 1998 Stock Option/Stock Issuance Plan shall accelerate if the About stockholders approve the adoption of the merger agreement. These options may be exercised immediately prior to the effective time of the merger and exchanged for shares of PRIMEDIA common stock in the merger. If they are not exercised, these options will terminate upon completion of the merger.

Immediately prior to the merger, each outstanding purchase right under About's employee stock purchase plan will be exercised for shares of About at the price per share under the plan. The shares will then be considered outstanding for purposes of the merger.

RESTRICTIONS ON SALES OF SHARES OF AFFILIATES OF PRIMEDIA AND ABOUT

The shares of PRIMEDIA common stock to be issued in connection with the merger will be registered under the Securities Act and will be freely transferable under the Securities Act, except for shares issued to any person who is deemed to be an "affiliate" of About at the time of its special

66

meeting. About expects that each of those affiliates will agree with PRIMEDIA that the affiliate will not transfer any shares of PRIMEDIA stock received in the merger except in compliance with the Securities Act. This joint proxy statement-consent solicitation-prospectus does not cover resales of PRIMEDIA common stock by affiliates of PRIMEDIA and About.

STOCK EXCHANGE LISTING

PRIMEDIA will use its reasonable efforts to cause the following shares of PRIMEDIA to be approved for listing on the New York Stock Exchange, subject to official notice of issuance, before the completion of the merger:

- PRIMEDIA common stock to be issued in the merger; and

- PRIMEDIA common stock reserved for issuance upon exercise of About stock options.

It is a condition to completion of the merger that the listing of the PRIMEDIA common stock to be issued in the merger be effected.

APPRAISAL RIGHTS

Under Delaware law, the common stockholders of PRIMEDIA and About are not entitled to appraisal rights in connection with the merger.

DELISTING AND DEREGISTRATION OF ABOUT STOCK AFTER THE MERGER

When the merger is completed, the About stock will be delisted from the Nasdaq National Market and deregistered under the Securities Exchange Act.

THE MERGER AGREEMENT

This section of the joint proxy statement-consent solicitation-prospectus describes the material terms of the merger agreement.

We urge you to read the full text of the merger agreement.

COMPLETION OF THE MERGER. The merger will be completed when we file a certificate of merger with the Delaware Secretary of State. However, we may agree to a later time for completion of the merger and specify that time in the certificate of merger. We will file the certificate of merger as soon as practicable after the satisfaction or waiver of the closing conditions in the merger agreement, which are described below.

We expect to complete the merger by February 26, 2001.

CONDITIONS TO COMPLETION OF THE MERGER.

CONDITIONS TO BOTH PARTIES' OBLIGATIONS. We may not complete the merger unless each of the following conditions is satisfied:

- no restraining order or injunction prohibiting completion of the merger is in effect;

- any waiting period applicable to the merger under the federal antitrust laws shall have terminated or expired;

- the registration statement of which this joint proxy statement-consent solicitation-prospectus is a part has been declared effective by the Securities and Exchange Commission and is not subject

67

to any stop order or proceedings seeking a stop order and PRIMEDIA has received all state securities and blue sky permits necessary to issue the PRIMEDIA common stock in the merger;

- the shares of PRIMEDIA common stock issuable to the holders of About stock pursuant to the merger agreement have been approved for listing on the New York Stock Exchange, subject to official notice of issuance; and

- any waiting period under the proxy rules applicable to PRIMEDIA shall have expired.

CONDITIONS TO EACH PARTY'S OBLIGATIONS. Each party's obligation to complete the merger is also subject to the satisfaction or waiver of the following additional conditions:

- the representations and warranties of the other party must be true and correct as of the date of the merger agreement and, unless the representations and warranties speak as of an earlier date, as of the closing date of the merger, subject, in most cases, to any exceptions that do not have, and could not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the other party;

- each party has received an opinion from its tax counsel that the merger will be treated as a tax-free reorganization for United States federal income tax purposes;

- at any time on or after the date of the merger agreement no condition or event has occurred which could, individually or in the aggregate, reasonably be likely to have a material adverse effect on either party;

- no governmental authority has threatened to or brought an action before any United States court or other governmental body of competent jurisdiction which challenges or seeks to restrain or prohibit the consummation of the merger; and

- all approvals or consents of any governmental authority in connection with the merger and the other transactions contemplated by the merger agreement must have been obtained, and all approvals or consents must be in full force and effect.

In addition, PRIMEDIA's obligation to complete the merger is subject to the satisfaction or waiver of the following additional conditions:

- PRIMEDIA has received from About a letter identifying all affiliates of About and a letter from each affiliate;

- PRIMEDIA has received comfort letters from About's accountants;

- Each member of the board of directors of About has delivered to About his or her written resignation as a director of About; and

- Messrs. Kurnit and Day have been employed by About and shall be ready, willing and able to begin employment with PRIMEDIA.

For purposes of the merger agreement, the term "material adverse effect" means, with respect to either of us, a material adverse change or effect that would be materially adverse to the business, properties, assets, condition (financial or otherwise), or results of operations of our respective companies and subsidiaries taken as a whole or that would materially impair the ability of our respective companies to perform our obligations under the merger agreement. However, any change or event caused by or resulting from the following will not be deemed to have a material adverse effect:

- any employee attrition after the date of the merger agreement;

- any change arising from the public announcement of the merger and the transactions contemplated by the merger agreement;

68

- any change in the market price or trading volume of our respective common stock; or

- any adverse effect attributable solely to conditions affecting the business-to-consumer Internet industry or the publishing business, as applicable, the United States economy as a whole or foreign economies in locations where either of us or our affiliates has material operations or sales (and not having a disproportionate effect on either of us).

NO SOLICITATIONS OF ALTERNATIVE TRANSACTIONS. The merger agreement contains detailed provisions prohibiting About from seeking an alternative transaction to the merger. Under these "no solicitation" provisions, About has agreed that it will not:

- initiate, solicit, knowingly encourage or otherwise facilitate any inquires or the making of an acquisition proposal, as described below; or

- have any discussions with, or provide any confidential information or data to, any person relating to an acquisition proposal, or engage in any negotiations concerning an acquisition proposal, or knowingly facilitate any effort or attempt to make or implement an acquisition proposal or accept an acquisition proposal.

For purposes of the merger agreement, the term "acquisition proposal" means any proposal or offer with respect to, or a transaction to effect:

- a merger, reorganization, share exchange, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving About or any of its subsidiaries; or

- any purchase or sale of all or any significant portion of About's assets or 15% or more of the equity securities of About or any of its subsidiaries.

The merger agreement permits About to comply with Rule 14e-2 under the Securities Exchange Act with regard to an acquisition proposal. In addition, if About receives an unsolicited bona fide written acquisition proposal, it may engage in discussions or negotiations with, or provide information to, the person making that acquisition proposal if:

- About has not yet held its stockholder meeting to vote on the adoption of the merger agreement;

- the acquisition proposal is a superior proposal, as described below, and was not solicited by the board of directors or the result of a breach of About's confidentiality obligations under the merger agreement;

- About's board of directors determines in good faith, based on the advice of its outside legal advisors, that the failure to participate in discussions or negotiations with, or to provide information to the person making the superior proposal would be in violation of its fiduciary duties under applicable law;

- before providing any information or data, About enters into a confidentiality agreement with the person making the proposal having terms that are no less favorable to About than those in the confidentiality agreement between About and PRIMEDIA; and

- before providing any information or data to any person or entering into discussions or negotiations with any person, the board of directors of About notifies PRIMEDIA promptly of:

- inquiries, proposals or offers received by, any information requested from, or any discussions or negotiations sought to be initiated or continued with, any of its representatives; and

- the identity of the person and the material terms and conditions of any proposals or offers.

69

About will also inform PRIMEDIA reasonably promptly of any material change in the terms of any proposal or offer and in any event notify PRIMEDIA 24 hours in advance before an agreement is reached.

For purposes of the merger agreement, "superior proposal" means a bona fide written acquisition proposal to acquire a majority of the assets or voting power of About which the board of directors of About concludes in good faith, after consultation with a financial advisor, taking into account all legal, financial, regulatory and other aspects of the proposal and the person making the proposal:

- is more favorable to the stockholders of About from a financial point of view than the merger; and

- is reasonably capable of being completed.

About has agreed in the merger agreement that:

- it will immediately terminate any activities, discussions or negotiations existing as of the date of the merger agreement with any parties conducted before that date with respect to any acquisition proposal; and

- it will promptly inform its directors, officers, employees and representatives of the foregoing restrictions in the merger agreement.

Nothing contained in the "no solicitation" provisions of the merger agreement will permit About to terminate the merger agreement or affect any of its other obligations under the merger agreement.

BOARD OF DIRECTOR'S COVENANT TO RECOMMEND MERGER. In the merger agreement, About's board of directors agreed to recommend to its stockholders that they vote to adopt the merger agreement at the special stockholder's meeting that it will hold for that purpose and to take all reasonable and lawful action to solicit stockholder approval. About's board of directors may not withdraw, amend or modify its recommendation in a manner that is adverse to PRIMEDIA, except if:

- it has complied with the "no-solicitation" provisions described above;

- an unsolicited superior proposal is pending at the time of the withdrawal, amendment or modification;

- it notifies PRIMEDIA of the superior proposal at least three business days in advance of the withdrawal, amendment or modification; and

- PRIMEDIA has not, during the period before the withdrawal, amendment or modification, offered to enter into a transaction with About on substantially the same or more favorable financial terms to About as the superior proposal.

In the event that About's board of directors makes a withdrawal, amendment or modification, About still must call a special meeting of its stockholders to consider and vote upon the merger agreement. About is not relieved from its obligations described above by the commencement, public proposal, public disclosure or communication of any acquisition proposal.

TERMINATION. We may terminate the merger agreement at any time prior to the completion of the merger, whether before or after the About stockholder approval has been obtained, by mutual written consent.

In addition, either of us may terminate the merger agreement:

- if the merger is not completed on or before June 30, 2001, except that this right to terminate will not be available to any party whose failure to perform its obligations under the merger agreement has been the cause of the failure of the merger to be completed by June 30, 2001;

70

- if the approval of the stockholders of About is not obtained by reason of the failure to obtain the required vote at its stockholders' meeting; or

- if any governmental entity of competent jurisdiction issues a final order or ruling or takes any other final action restraining, enjoining or otherwise prohibiting the merger, and the order, ruling or other action has become final and nonappealable.

About may terminate the merger agreement:

- if PRIMEDIA breaches any of its representations and warranties contained in the merger agreement which could reasonably be expected to have a material adverse effect upon PRIMEDIA, as described above, or materially adversely affect or delay the completion of the merger; or

- if PRIMEDIA fails to cure within ten days following notice of any breach of a covenant or agreement contained in the merger agreement which could reasonably be expected to have a material adverse effect upon PRIMEDIA, as described above, or materially adversely affect or delay the completion of the merger.

PRIMEDIA may terminate the merger agreement:

- if About breaches any of its representations and warranties contained in the merger agreement which could reasonably be expected to have a material adverse effect upon About, as described above, or materially adversely affect or delay the completion of the merger;

- if About fails to cure within ten days following notice of any breach of a covenant or agreement contained in the merger agreement which could reasonably be expected to have a material adverse effect upon About, as described above, or materially adversely affect or delay the completion of the merger;

- if About's board of directors fails to recommend or withdraws, modifies or amends in any respect adverse to PRIMEDIA its approval or recommendation of the merger agreement, the merger, or any of the transactions contemplated thereby, or approves or recommends a superior proposal;

- if About breaches any of its obligations under the "no solicitation" provisions described above; or

- if any person or group becomes the beneficial owner of at least 25% of About's stock or acquires 25% or more of the assets of About and its subsidiaries, taken as a whole.

TERMINATION FEES. The merger agreement provides that About may be required to pay a termination fee to PRIMEDIA of $23.5 million within two business days in the following circumstances:

- About's board of directors fails to recommend or withdraws, modifies or amends in any respect adverse to PRIMEDIA its approval or recommendation of the merger agreement, the merger, or any of the transactions contemplated thereby, or approves or recommends a superior proposal;

- any person or group becomes the beneficial owner of at least 25% of About's stock or acquires 25% or more of the assets of About and its subsidiaries, taken as a whole; or

- About enters into an alternative transaction within 18 months after the termination of the merger agreement by:

- either party because the approval of the stockholders of About is not obtained by reason of the failure to obtain the required vote at its stockholders' meeting;

71

- PRIMEDIA because About breaches any of its representations and warranties contained in the merger agreement which could reasonably be expected to have a material adverse effect upon About, as described above, or materially adversely affect or delay the completion of the merger; or

- PRIMEDIA because About fails to cure within ten days following notice of any breach of a covenant or agreement contained in the merger agreement which could reasonably be expected to have a material adverse effect upon About, as described above, or materially adversely affect or delay the completion of the merger.

About will also pay PRIMEDIA's out-of-pocket expenses and fees in connection with the transactions contemplated by the merger agreement up to $1 million within two business days if the merger agreement is terminated because:

- the approval of the stockholders of About is not obtained by reason of the failure to obtain the required vote at its stockholders' meeting;

- About breaches any of its representations and warranties contained in the merger agreement which could reasonably be expected to have a material adverse effect upon About, as described above, or materially adversely affect or delay the completion of the merger;

- any person or group becomes the beneficial owner of at least 25% of About's stock or acquires 25% or more of the assets of About and its subsidiaries, taken as a whole.

BENEFITS MATTERS. Until December 31, 2001, PRIMEDIA will provide compensation and benefits to About employees on terms no less favorable in the aggregate to the benefit plans in effect immediately prior to the completion of the merger (other than equity-based compensation). For purposes of determining eligibility to participate and vesting in benefit plans, PRIMEDIA will give effect to years of service with About in the same manner that credit for years of service was given by About. No employee electing coverage under the medical insurance plans of PRIMEDIA will be excluded from coverage on the bases of a pre-existing condition that was not also excluded under About's medical insurance plan.

73

AMENDMENT, EXTENSION AND WAIVER. We may amend the merger agreement by action taken or authorized by our respective boards of directors, at any time before or after adoption of the merger agreement by About's stockholders. After adoption of the merger agreement by About's stockholders, no amendment may be made which by law requires further approval by About's stockholders, unless that further approval is obtained. All amendments to the merger agreement must be in writing signed by both of us.

At any time before the completion of the merger, we may:

- extend the time for the performance of any of the obligations or other acts provided for in the merger agreement;

- waive any inaccuracies in the representations and warranties contained in the merger agreement or in any document delivered pursuant to the merger agreement; and

- waive compliance with any of the agreements or conditions contained in the merger agreement, subject to the requirements of applicable law.

The failure of either of us to assert any of our rights under the merger agreement or otherwise does not constitute a waiver of those rights.

FEES AND EXPENSES. Except in certain cases where About is responsible for up to $1 million of PRIMEDIA's expenses, whether or not the merger is completed, all costs and expenses incurred in connection with the merger agreement and the merger will be paid by the party incurring the expenses. However, each of PRIMEDIA and About will pay one-half of the costs and expenses incurred in printing and mailing this joint proxy statement-consent solicitation-prospectus.

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

The unaudited pro forma statements of consolidated operations for the nine months ended September 30, 2000 and the year ended December 31, 1999 give effect to the acquisition of all of the outstanding common stock of About as if it had occurred on January 1, 1999. The unaudited pro forma consolidated balance sheet as of September 30, 2000 gives effect to the acquisition of About as if it had occurred on September 30, 2000 based on the purchase method of accounting.

PRIMEDIA believes the accounting used for the pro forma adjustments provides a reasonable basis on which to present the unaudited pro forma consolidated financial statements. The pro forma adjustments do not include any synergies expected to be derived from the merger. In addition, the pro forma adjustments do not include the pro forma impact of PRIMEDIA's and About's acquisitions during 1999 and 2000 because the impact of such acquisitions is not significant to the consolidated entity. The pro forma statements of consolidated operations and pro forma consolidated balance sheet are unaudited and were derived by adjusting the historical consolidated financial statements of PRIMEDIA and About. THE UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS ARE PROVIDED FOR INFORMATIONAL PURPOSES ONLY AND SHOULD NOT BE CONSTRUED TO BE INDICATIVE OF PRIMEDIA'S CONSOLIDATED FINANCIAL POSITION OR RESULTS OF OPERATIONS HAD THE TRANSACTION BEEN CONSUMMATED ON THE DATE ASSUMED AND DO NOT PROJECT PRIMEDIA'S CONSOLIDATED FINANCIAL POSITION OR RESULTS OF OPERATIONS FOR ANY FUTURE DATE OR PERIOD.

The unaudited pro forma consolidated financial statements and accompanying notes should be read in conjunction with the PRIMEDIA historical consolidated financial statements and notes thereto included in PRIMEDIA's Annual Report on Form 10-K for the year ended December 31, 1999 and in PRIMEDIA's Quarterly Report on Form 10-Q for the quarter ended September 30, 2000, as well as the About historical consolidated financial statements and notes thereto included in About's Annual Report on Form 10-K for the year ended December 31, 1999 and in About's Quarterly Report on Form 10-Q for the quarter ended September 30, 2000.

NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
(DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

(a) For purposes of these pro forma consolidated financial statements, PRIMEDIA has assumed that the value of the total purchase consideration based on shares to be issued in order to consummate the acquisition of About would be approximately $536,000. PRIMEDIA has assumed that it will issue 2.3409 shares of PRIMEDIA common stock for each share of About stock. Under the terms of the arrangement, stockholders of About will receive approximately 45,200,000 shares of PRIMEDIA common stock. PRIMEDIA has assumed that the value of its shares of common stock to be issued will be $11.81 per share, based on the weighted-average market values for the two days prior and two days succeeding the acquisition announcement date. In addition, upon the completion of the merger, certain options previously granted to the About directors will become immediately vested and exercisable. The shares of PRIMEDIA common stock to be issued in connection with these stock option exercises were included in the determination of purchase price, net of the related cash proceeds from the exercises.

PRIMEDIA will replace outstanding options to purchase shares of About common stock held by certain individuals with options to purchase shares of PRIMEDIA common stock. The PRIMEDIA options will have the same terms and conditions as the About stock options, except that the number of options and their exercise price will be adjusted based on the exchange ratio (2.3409 to 1) used to consummate the merger. The following assumptions were used regarding the PRIMEDIA options to be issued based on About's outstanding options at September 30, 2000.

                                                                              WEIGHTED-AVERAGE
                                                                              EXERCISE PRICE OF
                                                              NUMBER OF           PRIMEDIA
                                        ORIGINAL NUMBER    PRIMEDIA OPTIONS        OPTIONS
                                        OF ABOUT OPTIONS     TO BE ISSUED       TO BE ISSUED
                                        ----------------   ----------------   -----------------
Vested................................       953,613           2,232,312           $ 8.93
Unvested..............................     4,202,879           9,838,521           $14.94
                                           ---------          ----------
Total.................................     5,156,492          12,070,833           $13.83
                                           =========          ==========

The estimated fair value of the fully vested and unvested options to be issued is approximately $107,000. This value was determined using a Black Scholes pricing model based on the following weighted-average assumptions:

Risk free interest rate of 5.84%; Volatility of 72.47%;
Expected term ranging from 6.66 to 9.75 years; Expected dividend yield of 0%; and Value of PRIMEDIA common stock of $11.81 per share.

It has been assumed that on the date that the Company grants these unvested replacement options, there is no intrinsic value of the unvested replacement options since the weighted-average exercise price of the replacement options of $14.94 per share approximates the assumed fair market value of PRIMEDIA common stock of $15.25 per share, which corresponds to PRIMEDIA's October 27, 2000 (the date of the merger agreement) closing price. Further, the annual expense which would result had any intrinsic value been attributed to the unvested replacement options is inconsequential and approximates the amortization of the related goodwill. Accordingly, no allocation of fair value has been made for the intrinsic value of unvested options.

The following is a summary of the calculation of the purchase price, as described above, as well as the allocation of the purchase price to the fair value of the net assets acquired:

Total number of shares of PRIMEDIA common stock to be issued
  to consummate the acquisition.............................   45,200,000
Shares to be issued in connection with options which are
  vested or will become vested prior to or as a result of
  the merger................................................      170,418
                                                              -----------
Total shares of PRIMEDIA common stock to be issued..........   45,370,418
Assumed fair value per share of PRIMEDIA common stock.......  $     11.81

                                                              -----------

Add: Estimated direct merger costs of About.................        7,000
Less: Fair value of net tangible assets of About............      168,502
                                                              -----------
Excess of purchase price over net assets acquired...........  $   491,403
                                                              ===========

PRIMEDIA's management determined that the utilization of About's historical net operating losses was not likely. Therefore, no deferred tax assets have been recorded in connection with the merger.

The purchase price has been allocated based on management's best estimate of the fair value of assets acquired and the liabilities assumed based on the historical financial statements of About as of September 30, 2000. The excess purchase price over the fair value of net tangible assets acquired has been allocated to goodwill. This adjustment is based upon preliminary estimates to reflect the allocation of purchase consideration to the acquired assets and liabilities of About. The final allocation of the purchase consideration will be determined after the completion of the merger and will be based on appraisals and a comprehensive final evaluation of the fair values and useful lives of About's tangible assets acquired, identifiable intangible assets and excess of purchase price over net assets acquired at the time of the merger. The final determination may result in asset and liability fair values that are different than the preliminary estimates of these amounts. For purposes of purchase price allocation, it has been assumed that the fair value of deferred revenues approximates About's historical carrying value. At the merger date, the fair value of About's deferred revenues will represent the fair value of the contractual performance obligation based upon the nature of the activities to be performed and the related costs to be incurred. The adjustment to the historical carrying value, if any, will not have a material impact on PRIMEDIA's financial position or results of operations.

(b) To eliminate the historical equity accounts of About.

(c) To reflect the unearned compensation expense in connection with the employment agreements of Scott P. Kurnit and William C. Day. In connection with their employment agreements, Messrs. Kurnit and Day will be granted options to purchase 2,605,300 shares and 877,000 shares, respectively, of PRIMEDIA common stock at an exercise price equal to thirty percent of the fair market value per share on that date. Accordingly, the adjustment reflects a 70% market value discount ($10.68 per share) based on a PRIMEDIA per share market value of $15.25 which was the closing price on October 27, 2000. These options vest at a rate of 25% per year and are subject to Messrs. Kurnit's and Day's continued employment. Accordingly, the compensation expense reflected for the nine months ended September 30, 2000 and the year ended December 31, 1999 reflects this pro rata vesting on a graded basis.

A one dollar change in the fair market value of PRIMEDIA common stock would change the unearned compensation recognized at September 30, 2000 by approximately $2,400. This same one dollar change would change the compensation expense recognized during the nine months ended

81

September 30, 2000 and the year ended December 31, 1999 by approximately $495 ($.002 per share) and approximately $1,270 ($.01 per share), respectively.

(d) To reflect the unearned compensation expense in connection with the employment agreements of Messrs. Kurnit and Day. In connection with their employment agreements, Messrs. Kurnit and Day will be granted 2,211,100 shares and 744,350 shares, respectively, of restricted PRIMEDIA common stock. Accordingly, the adjustment assumes a PRIMEDIA per share market value of $15.25, which was the closing price on October 27, 2000. These shares of restricted PRIMEDIA common stock vest at a rate of 25% per year and are subject to Messrs. Kurnit's and Day's continued employment. Accordingly, the compensation expense reflected for the nine months ended September 30, 2000 and the year ended December 31, 1999 reflects this pro rata vesting on a graded basis.

A one dollar change in the fair market value of PRIMEDIA common stock would change the unearned compensation recognized at September 30, 2000 by approximately $2,955. This same one dollar change would change the compensation expense recognized during the nine months ended September 30, 2000 and the year ended December 31, 1999 by approximately $600 ($.003 per share) and approximately $1,540 ($.01 per share), respectively.

(e) To reflect additional compensation expense to be incurred in connection with the employment agreements of Messrs. Kurnit and Day.

Potential pro forma adjustments relating to eligible bonuses, the minimum amount of which is $2,300 ($.01 per share for the year ended December 31, 1999), have been omitted since the payment of such bonuses is dependent upon the achievement of performance goals to be established by PRIMEDIA's management.

Potential pro forma adjustments relating to sign-on bonuses for Messrs. Kurnit and Day totaling $49 have been omitted since the impact would not be material to the pro forma financial statements.

In addition, Messrs. Kurnit and Day also entered into share lock-up agreements with PRIMEDIA, pursuant to which each agreed to specific restrictions regarding the transferability of his shares of PRIMEDIA common stock issued in the merger. Under the terms of these agreements, during the first year after the closing of the merger, Messrs. Kurnit and Day may sell a portion of their shares of PRIMEDIA common stock, subject to PRIMEDIA's right of first refusal with respect to any sale. In addition, Messrs. Kurnit and Day were guaranteed a minimum per share sales price of $15.25 on 1,639,344 shares ($25,000) and 532,786 shares ($8,125), respectively. In the event of any per share shortfall upon sale, PRIMEDIA will pay them the difference between the $15.25 per share and the actual per share sales price for each share sold and that difference will be recorded as additional compensation expense for PRIMEDIA. The pro forma financial statements do not reflect the impact, if any, of these agreements.

(f) To adjust pro forma amortization expense based on the estimated excess of purchase price over net assets acquired related to the merger. This excess is assumed to be amortized over an estimated useful life of three years. PRIMEDIA believes that a three-year life is responsive to the rapid rate of change in the Internet industry and is consistent with other recent mergers of a comparable nature. The final allocation of purchase price may result in amortization expense that is different than the preliminary estimate of this amount. The pro forma adjustment represents the difference between the amortization of the $491,403 excess of purchase price over net assets acquired over a three year period and About's historical amortization.

(g) The pro forma adjustments reflect the additional shares to be issued based on the exchange ratio used to consummate the merger, include the additional shares to be issued in connection with options that will become vested prior to or as a result of the merger and include the additional shares of restricted PRIMEDIA common stock to be issued to Messrs. Kurnit and Day in connection with their employment agreements. Pro forma loss per share has been determined based on pro forma net loss after preferred stock dividends divided by the weighted average number of shares of PRIMEDIA common stock outstanding for all periods presented. Stock options were not included in the computation of pro forma loss per share because the effect of their inclusion would be antidilutive.

DESCRIPTION OF PRIMEDIA CAPITAL STOCK

GENERAL

As of September 30, 2000, PRIMEDIA had 300,000,000 shares of authorized capital stock. Those shares consisted of:

- 250,000,000 shares of common stock, of which 166,765,849 shares were outstanding; and

- 50,000,000 shares of preferred stock, of which:

- 2,000,000 shares were designated Series D Exchangeable Preferred Stock, all which were outstanding;

- 1,250,000 shares were designated Series F Exchangeable Preferred Stock, all which were outstanding; and

- 2,500,000 shares were designated Series H Exchangeable Preferred Stock, all which were outstanding.

DESCRIPTION OF PRIMEDIA COMMON STOCK

The rights of About stockholders who acquire shares of PRIMEDIA common stock offered by this joint proxy statement-consent solicitation-prospectus will be governed by PRIMEDIA's certificate of incorporation and by-laws and Delaware corporate law. We have summarized below provisions of our certificate of incorporation. This summary does not contain all of the provisions that you may want to consider as an investor in PRIMEDIA's securities. You may wish to review our certificate of incorporation and by-laws. PRIMEDIA has filed a copy of its certificate of incorporation and by-laws with the SEC. See "Where You Can Find More Information."

DIVIDENDS. The owners of PRIMEDIA common stock may receive dividends when declared by the board of directors out of funds legally available for the payment of dividends. PRIMEDIA has no present intention of declaring and paying cash dividends on the common stock at any time in the foreseeable future. The terms of PRIMEDIA's credit agreements, indentures and preferred stocks restrict PRIMEDIA from declaring and paying cash dividends on the common stock. See "Risk Factors."

VOTING RIGHTS. Each share of common stock is entitled to one vote in the election of directors and all other matters submitted to stockholder vote. There are no cumulative voting rights.

LIQUIDATION RIGHTS. If PRIMEDIA liquidates, dissolves or winds-up its business, whether voluntarily or not, PRIMEDIA's common stockholders will share equally in the distribution of all assets remaining after payment to creditors and preferred stockholders.

PREEMPTIVE RIGHTS. The common stock has no preemptive or similar rights.

LISTING. PRIMEDIA's common stock is listed on the New York Stock Exchange under the symbol "PRM."

ANTI-TAKEOVER PROVISIONS. PRIMEDIA is subject to the provisions of Delaware law described below regarding business combinations with interested stockholders.

Section 203 of the Delaware General Corporation Law applies to a broad range of business combinations between a Delaware corporation and an interested stockholder. The Delaware law definition of "business combination" includes mergers, sales of assets, issuances of voting stock and certain other transactions. An "interested stockholder" is defined as any person who owns, directly or indirectly, 15% or more of the outstanding voting stock of a corporation.

83

Section 203 prohibits a corporation from engaging in a business combination with an interested stockholder for a period of three years following the date on which the stockholder became an interested stockholder, unless:

- the board of directors approved the business combination before the stockholder became an interested stockholder, or the board of directors approved the transaction that resulted in the stockholder becoming an interested stockholder;

- upon completion of the transaction which resulted in the stockholder becoming an interested stockholder, such stockholder owned at least 85% of the voting stock outstanding when the transaction began other than shares held by directors who are also officers and other than shares held by certain employee stock plans; or

- the board of directors approved the business combination after the stockholder became an interested stockholder and the business combination was approved at a meeting by at least two-thirds of the outstanding voting stock not owned by such stockholder.

These limitations on business combinations with interested stockholders do not apply to a corporation that does not have a class of stock listed on a national securities exchange, authorized for quotation on an interdealer quotation system of a registered national securities association or held of record by more than 2,000 stockholders.

DESCRIPTION OF SERIES D EXCHANGEABLE PREFERRED STOCK

RANK. The Series D Preferred Stock ranks as to dividend rights and rights on liquidation, winding-up or dissolution:

- senior to all classes of common stock and all classes of capital stock or other series of preferred stock which does not expressly provide that it ranks senior to or on parity with the Series D Preferred Stock;

- on a parity with the Series F Preferred Stock, the Series H Preferred Stock, and all classes of capital stock or other series of preferred stock which expressly provides that it ranks on parity with the Series D Preferred Stock; and

- junior to each class of capital stock or other series of preferred stock which expressly provides that it ranks senior to the Series D Preferred Stock.

DIVIDENDS. Holders of the Series D Preferred Stock are entitled to receive, when as and if declared by the board of directors of PRIMEDIA, out of funds legally available for the payment of dividends, dividends in cash at an annual rate equal to 10% of the liquidation preference. Dividends on the Series D Preferred Stock are payable quarterly in arrears on February 1, May 1, August 1 and November 1 of each year. Dividends will cumulate without interest until declared and paid. As of the date of this prospectus, PRIMEDIA has paid all such dividends.

OPTIONAL REDEMPTION. Subject to contractual and other restrictions and the existence of legally available funds, PRIMEDIA, at its option, may at any time on or after February 1, 2001, redeem the Series D Preferred Stock in whole or in part, at redemption prices declining ratably from $105 beginning on February 1, 2001, to $100 on and after February 1, 2006, plus accrued and unpaid dividends.

MANDATORY REDEMPTION. Subject to contractual and other restrictions and to the existence of legally available funds, on February 1, 2008, PRIMEDIA will be required to redeem all outstanding shares of Series D Preferred Stock at a price equal to $100 per share plus all accumulated and unpaid dividends to the date of redemption.

COMPARISON OF STOCKHOLDER RIGHTS

PRIMEDIA and About are both organized under the laws of the State of Delaware. Any differences, therefore, in the rights of holders of PRIMEDIA capital stock and About capital stock arise primarily from differences in their respective certificates of incorporation and by-laws. After the effective time of the merger, the rights of About stockholders will be determined by reference to the PRIMEDIA certificate of incorporation and by-laws.

For a description of the voting rights of the PRIMEDIA preferred stock, see "Description of PRIMEDIA Capital Stock--Description of Series D Exchangeable Preferred Stock," "--Description of Series F Exchangeable Preferred Stock," and "--Description of Series H Exchangeable Preferred Stock."

NUMBER AND ELECTION OF DIRECTORS

The amended and restated by-laws provide that the PRIMEDIA board of directors will consist of not less than one or more than fifteen directors, the number to be fixed from time to time by the PRIMEDIA board of directors or the stockholders.

PRIMEDIA's certificate of incorporation and amended and restated by-laws do not provide for a staggered board of directors.

ABOUT. The board of directors of About currently has six members. About's second amended and restated certificate of incorporation states that the number of directors will in no case be less than five nor more than 15 (exclusive of directors, if any, to be elected by holders of preferred stock of About, voting separately as a class).

About's second amended and restated certificate of incorporation and amended and restated by-laws do not provide for a staggered board of directors.

VACANCIES ON THE BOARD OF DIRECTORS AND REMOVAL OF DIRECTORS

PRIMEDIA.

A director may be removed with or without cause by the stockholders.

89

ABOUT. The amended and restated by-laws provide that vacancies and newly created directorships are filled by a vote of 66.67% of the directors then in office, for a term expiring at the annual meeting of stockholders, at which time the director's successor is elected by the stockholders. If there are no directors in office or if the directors then in office constitute less than a majority, the vacancy shall be filled pursuant to Delaware law. Any director or the entire board of directors may be removed at any time, but only for cause and only by the affirmative vote of the holders of not less than 66.67% of the outstanding shares of About capital stock entitled to vote in the election of directors.

AMENDMENTS TO THE CERTIFICATE OF INCORPORATION

PRIMEDIA. The provisions of Delaware law regarding amendments to the certificate of incorporation govern the amendment of certificates of incorporation of PRIMEDIA. Under Delaware law, an amendment to the certificate of incorporation of a corporation requires the approval of the corporation's board of directors and the approval of holders of a majority of the outstanding stock entitled to vote upon the proposed amendment, unless a higher vote is required by the corporation's certificate of incorporation.

ABOUT. About's second amended and restated certificate of incorporation requires a vote of the holders of not less than 66.67% of the outstanding shares of capital stock of About in order to alter or amend the provisions of the certificate of incorporation relating to limitations on directors' liability, indemnification, amendment of the bylaws, or amendment of the certificate of incorporation. In all other cases, as provided under Delaware law, a vote of the holders of not less than a majority of the outstanding shares of capital stock of About is required.

If the date of the annual meeting is more than 30 days before or more than 60 days after the anniversary date of the proxy statement delivered to stockholders in connection with the preceding year's annual meeting, or if no proxy statement was delivered to stockholders in connection with the preceding year's annual meeting, notice will also be timely if delivered within earlier than the close of business on the 90th day prior to the annual meeting and not later than the close of business on the later of the 60th day prior to the annual meeting or the close of business on the tenth day following the day on which public announcement of the date of the meeting is first made by About.

In addition, if the number of directors to be elected is increased and no public announcement is made by About naming all of the nominees or specifying the size of the increased board of directors at least 70 days before the first anniversary of the preceding year's annual meeting (or, if the annual meeting is held more than 30 days before or 60 days after such anniversary date, at least 70 days prior to such annual meeting), a stockholder's notice will be considered timely, with respect to the nominees for any new positions created by the increase if it is delivered to the secretary of About not later than the close of business on the tenth day following the day on which the public announcement is first made by About.

LIMITATION OF PERSONAL LIABILITY OF DIRECTORS AND OFFICERS

Delaware law provides that a corporation may include in its certificate of incorporation a provision limiting or eliminating the liability of its directors to the corporation and its stockholders for monetary damages arising from a breach of fiduciary duty, except for:

- a breach of the duty of loyalty to the corporation or its stockholders;

- acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

- payment of a dividend or the repurchase or redemption of stock in violation of Delaware law; or

- any transaction from which the director derived an improper personal benefit.

The certificate of incorporation, as amended, of PRIMEDIA and the second amended and restated certificate of incorporation of About provide that, to the fullest extent Delaware law permits the limitation or elimination of the liability of directors, no director will be liable to PRIMEDIA or About, as the case may be, or their respective stockholders for monetary damages for breach of fiduciary duty as a director.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

Under Delaware law, a corporation generally may indemnify directors and officers:

- for actions taken in good faith and in a manner they reasonably believed to be in, or not opposed to, the best interests of the corporation; and

- with respect to any criminal proceeding, if they had no reasonable cause to believe that their conduct was unlawful.

In addition, Delaware law provides that a corporation may advance to a director or officer expenses incurred in defending any action upon receipt of an undertaking by the director or officer to repay the amount advanced if it is ultimately determined that he or she is not entitled to indemnification.

92

PRIMEDIA. The amended and restated by-laws of PRIMEDIA provide that PRIMEDIA will indemnify to the fullest extent permitted by Delaware law any current or former director or officer of the corporation, and may, at the discretion of the board of directors, indemnify any current or former employee or agent of PRIMEDIA against all expenses, judgments, fines and amounts paid in settlement in connection with any threatened, pending or completed action, suit or proceeding in which the person was involved because of that person's service, at the request of PRIMEDIA, as a director, officer, partner, trustee, employee or agent of another corporation, partnership, joint venture, trust, or other enterprise.

In addition, the amended and restated by-laws provide that the expenses incurred by a person who is or was a director or officer in connection with any action, suit or proceeding will be advanced to the director or officer by PRIMEDIA upon receipt of an undertaking by or on behalf of the director or officer to repay the amounts advanced if ultimately it is determined that the director or officer was not entitled to be indemnified against the expenses.

ABOUT. The amended and restated by-laws of About provide that About will indemnify to the fullest extent permitted by Delaware law any director or officer made, or threatened to be made, a party to an action or proceeding, whether criminal, civil, administrative or investigative, by reason of being a director or officer of About or a predecessor corporation, or, at About's request, a director or officer of another corporation. The indemnification provided by About is not exclusive of any other rights to which indemnified person may be entitled under any bylaw, agreement or vote of stockholders or disinterested directors or otherwise, continues as to an indemnified person who has ceased to be a director, and inures to the benefit of the heirs, executors and administrators of an indemnified person. About's obligation to provide indemnification is to be offset to the extent of any other source of indemnification or any otherwise applicable insurance coverage under a policy maintained by About or by any other person.

In addition, the amended and restated by-laws provide that the expenses incurred by a director or officer of About in defending a civil or criminal action, suit or proceeding by reason of the fact that the person is or was a director of About will be advanced to the person by About upon receipt of an undertaking by or on behalf of the director to repay the amounts advanced if ultimately it is determined that the director or officer was not entitled to be indemnified against the expenses. The indemnification provisions of the amended and restated by-laws also apply to all directors and officers who are or have been fiduciaries of any employee benefit plan of About.

STATE ANTI-TAKEOVER STATUTES

Under the business combination statute of Delaware law, a corporation is prohibited from engaging in any business combination with an interested stockholder who, together with its affiliates or associates, owns, or who is an affiliate or associate of the corporation and within a three-year period did own, 15% or more of the corporation's voting stock for a three-year period following the time the stockholder became an interested stockholder, unless:

- prior to the time the stockholder became an interested stockholder, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

- the interested stockholder owned at least 85% of the voting stock of the corporation, excluding specified shares, upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder; or

- at or subsequent to the time the stockholder became an interested stockholder, the business combination is approved by the board of directors of the corporation and authorized by the affirmative vote, at an annual or special meeting and not by written consent, of at least 66 2/3% of

93

the outstanding voting shares of the corporation, excluding shares held by that interested stockholder.

A business combination generally includes:

- mergers, consolidations and sales or other dispositions of 10% or more of the assets of a corporation to or with an interested stockholder;

- specified transactions resulting in the issuance or transfer to an interested stockholder of any capital stock of the corporation or its subsidiaries; and

- other transactions resulting in a disproportionate financial benefit to an interested stockholder.

The provisions of the Delaware business combination statute do not apply to a corporation if, subject to certain requirements, the certificate of incorporation or by-laws of the corporation contain a provision expressly electing not to be governed by the provisions of the statute or the corporation does not have voting stock listed on a national securities exchange, authorized for quotation on an inter-dealer quotation system of a registered national securities association or held of record by more than 2,000 stockholders.

Neither PRIMEDIA in its certificate of incorporation, as amended, or its amended and restated by-laws, nor About in its second amended and restated certificate of incorporation or its amended and restated by-laws, has adopted any provision to "opt-out" of the Delaware business combination statute and the statute is applicable to business combinations involving PRIMEDIA and About.

About has agreed to pay PRIMEDIA commission-based fees equal to 20% of the net advertising revenues derived only from such forms of advertising sold on these specific sites. From November 1, 2000 to March 31, 2001, the fees shall be payable only with respect to those sales actually generated by PRIMEDIA. From April 1, 2001 to December 31, 2005, the fees shall be payable regardless of whether the sales were generated by PRIMEDIA. About and PRIMEDIA also agreed that the number of About web sites to be covered by this agreement may grow to 20% of the total number of About web sites. This agreement is renewable for additional one-year terms until either party notifies the other party of its intent not to renew.

RIGHT OF FIRST OFFER AGREEMENT

On October 29, 2000, About and PRIMEDIA entered into a right of first offer agreement concerning the possible provision of content from publications that compete with PRIMEDIA publications. Under the terms of the agreement, if About proposes to enter into a license agreement under which it will pay for content from publications that compete with PRIMEDIA publications, PRIMEDIA has the right to provide such content on terms no less favorable to About if, in About's sole judgment, such content is identical in quality to that provided by the competitive publication. This agreement terminates on December 31, 2005.

LIST RENTAL AGREEMENT

Effective as of December 6, 2000, About and PRIMEDIA Magazines Inc. entered into an agreement pursuant to which PRIMEDIA Magazines Inc. granted About the right to use a mailing list owned by PRIMEDIA Magazines Inc. in exchange for 120,987 shares of About stock. About issued 120,987 shares of About stock to PRIMEDIA Magazines Inc. on December 6, 2000.

OTHER AGREEMENTS

About and PRIMEDIA have entered into certain agreements pursuant to which PRIMEDIA has agreed to purchase advertising and promotional services on the About network. The terms of these agreements expire in November of 2001 and December of 2002. One of these agreements, a sponsorship and advertising agreement, provides for payments to About in the aggregate of $5,900,000.

COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT

Section 16(a) of the Securities Exchange Act requires PRIMEDIA's and About's directors and executive officers, and persons who own more than 10% of either PRIMEDIA's or About's stock, to file with the Securities and Exchange Commission initial reports of ownership on a Form 3 and reports of changes in ownership of common stock and other equity securities of PRIMEDIA or About, as applicable on a Form 4 or Form 5. Officers, directors and 10% stockholders are required by SEC regulations to furnish PRIMEDIA or About, as applicable with, copies of all
Section 16(a) forms they file.

To PRIMEDIA's and About's knowledge, based solely on review of the copies of the reports furnished to PRIMEDIA and About and written representations from the executive officers and directors, PRIMEDIA and About believe that all
Section 16(a) filing requirements applicable to its officers, directors, and 10% stockholders were met during 2000, except with respect to initial statements of beneficial ownership for two directors of About, Daphne Kis and Stanley Fung, which statements were not filed on a timely basis but have subsequently been filed.

LEGAL MATTERS

Simpson Thacher & Bartlett, New York, New York, will provide an opinion for PRIMEDIA regarding the validity of the shares of PRIMEDIA offered by this joint proxy statement-consent solicitation-prospectus.

Simpson Thacher & Bartlett, New York, New York, counsel for PRIMEDIA, and Brobeck, Phleger & Harrison LLP, New York, New York, counsel for About, will provide opinions regarding certain United States federal income tax consequences of the merger for PRIMEDIA and About, respectively.

CHANGE IN INDEPENDENT PUBLIC ACCOUNTANTS

In June 2000, About decided to replace KPMG LLP as its independent accountants, and retained Ernst & Young LLP as its new independent accountants. The decision to change About's accountants was recommended by the audit committee of About's board of directors and approved by About's board of directors. KPMG LLP's reports on About's financial statements for the two most recent fiscal years (i.e., the fiscal years ended December 31, 1998 and December 31, 1999) contained no adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles.

During About's last two fiscal years and the subsequent interim period to the date hereof, there were no disagreements between About and KPMG LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of KPMG LLP, would have caused it to make reference to the subject matter of the disagreements in connection with its reports. Prior to retaining Ernst & Young LLP, About had not consulted with Ernst & Young LLP regarding accounting principles.

In addition, the proxies solicited by the About board of directors for the 2001 annual meeting of its stockholders will confer discretionary authority to vote on any stockholder proposal raised at the meeting which is not described in the 2001 proxy statement unless About has received notice of the proposal, as described above. However, if the date of its 2001 annual meeting of stockholders is more than 30 days before May 9, 2001 or more than 60 days after May 9, 2001, notice by the stockholder must be delivered after the close of business on the 90th day prior to the 2001 annual meeting and by the close of business on the 60th day prior to the 2001 annual meeting or the close of business on the 10th day following the date on which a public announcement of the 2001 annual meeting is first announced. If About determines to change the date of its 2001 annual meeting of stockholders more than 30 days from May 9, 2001, About will provide its stockholders with a reasonable time before it begins to print and mail its proxy materials for the 2001 annual meeting in order to allow its stockholders an opportunity to make proposals in accordance with the rules and regulations of the SEC.

ANNEX A

October 29, 2000

The Board of Directors
PRIMEDIA Inc. 745 Fifth Avenue
New York, New York 10151

Dear Members of the Board:

We understand that PRIMEDIA Inc., a Delaware corporation (the "COMPANY"), is considering a transaction whereby the Company will acquire About.com, Inc., a Delaware corporation ("ABOUT.COM"). Pursuant to the terms of an Agreement and Plan of Merger (the "PURCHASE AGREEMENT"), the Company will undertake a series of transactions whereby About.com will become a wholly owned subsidiary of the Company (the "TRANSACTION"). Pursuant to the terms of the Purchase Agreement all of the issued and outstanding shares of the capital stock of About.com, par value of $.001 per share ("ABOUT.COM COMMON STOCK") will be converted into 2.3409 shares of Common Stock, par value of $.01 per share, of the Company (the "EXCHANGE RATIO"). No Company Common Stock will be issued to holders of fractional shares of About.com Common Stock. The terms and conditions of the Transaction are more fully set forth in the Purchase Agreement.

You have requested our opinion as to whether the Exchange Ratio is fair, from a financial point of view, to the Company and to the holders of Company Common Stock.

Wit SoundView Corporation ("WIT") has acted as financial advisor to the Board of Directors of the Company in connection with the Transaction and will receive a fee upon the consummation thereof. In the past, Wit and its predecessors have provided investment banking services to the Company and received customary compensation for the rendering of such services. In the ordinary course of business, Wit, its successors and affiliates may trade securities of the Company for their own accounts and, accordingly, may at any time hold a long or short position in such securities.

Our opinion does not address the Company's underlying business decision to effect the Transaction or constitute a recommendation to any shareholder of the Company as to how such shareholder should vote with respect to the Transaction. At your direction, we have not been asked to, nor do we, offer any opinion as to the material terms of the Purchase Agreement or the form of the Transaction. In rendering this opinion, we have assumed, with your consent, that the Company and About.com will comply with all the material terms of the Purchase Agreement.

In arriving at our opinion, we have, among other things: (i) reviewed certain publicly available business and historical financial information relating to the Company and About.com, (ii) reviewed certain internal financial information and other data relating to the business and financial prospects of the Company, including estimates and financial forecasts prepared by management of the Company, that were provided to us by the Company and not publicly available, (iii) reviewed certain internal financial information and other data relating to the business and financial prospects of About.com, including estimates and financial forecasts prepared by the managements of the Company and About.com and not publicly available, (iv) conducted discussions with members of the senior managements of the Company and About.com, (v) reviewed publicly available financial and stock market data with respect to certain other companies in lines of business we believe to be generally comparable to those of the Company, (vi) compared the financial terms of the Transaction with the publicly available financial terms of certain other transactions which we believe to be generally relevant, (vii) considered certain pro forma effects of the Transaction on the Company's financial statements and reviewed certain estimates of synergies prepared by Company management, (viii) reviewed drafts of the


Purchase Agreement, and (ix) conducted such other financial studies, analyses, and investigations, and considered such other information as we deemed necessary or appropriate.

In connection with our review, at your direction, we have not assumed any responsibility for independent verification for any of the information reviewed by us for the purpose of this opinion and have, at your direction, relied on its being complete and accurate in all material respects. In addition, at your direction, we have not made any independent evaluation or appraisal of any of the assets or liabilities (contingent or otherwise) of the Company or About.com, nor have we been furnished with any such evaluation or appraisal. With respect to the financial forecasts, estimates, pro forma effects and calculations of synergies referred to above, we have assumed, at your direction, that they have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of each company as to the future performance of their respective companies. Our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof.

Based upon and subject to the foregoing, it is our opinion that, as the date hereof, the Exchange Ratio is fair, from a financial point of view, to the Company and to the holders of Company Common Stock.

Very truly yours,

WIT SOUNDVIEW CORPORATION

ANNEX B

October 29, 2000

Board of Directors
PRIMEDIA Inc.
745 Fifth Avenue
New York, New York 10151

Members of the Board of Directors:

PRIMEDIA Inc. (the "ACQUIROR"), Abracadabra Acquisition Corporation, a wholly owned subsidiary of the Acquiror (the "ACQUISITION SUB"), and About.com, Inc. (the "COMPANY") propose to enter into an Agreement and Plan of Merger dated as of October 29, 2000 (the "AGREEMENT") pursuant to which the Acquisition Sub will be merged with and into the Company in a transaction (the "MERGER") in which each outstanding share of the Company's common stock, par value $0.001 per share (the "SHARES"), will be converted into the right to receive 2.3409 shares (the "EXCHANGE RATIO") of the common stock, par value $0.01 per share, of the Acquiror (the "ACQUIROR SHARES").

You have asked us whether, in our opinion, as of the date hereof, the Exchange Ratio is fair from a financial point of view to the Acquiror.

In arriving at the opinion set forth below, we have, among other things:

(1) Reviewed certain publicly available business and financial information relating to the Company and the Acquiror that we deemed to be relevant;

(2) Reviewed certain information, including financial forecasts, relating to the business, earnings, cash flow, assets and prospects of the Company and the Acquiror, as well as the amount and timing of any cost savings and synergies expected to result from the Merger (the "EXPECTED SYNERGIES"), furnished to us by the Company and the Acquiror;

(3) Conducted discussions with members of senior management of the Company and the Acquiror concerning their respective businesses and prospects before and after giving effect to the Merger and the Expected Synergies;

(4) Reviewed the historical market prices and trading activity for the Shares and the Acquiror Shares and compared them with that of certain publicly traded companies which we deemed to be reasonably similar to the Company and the Acquiror, respectively;

(5) Compared the results of operations of the Company and the Acquiror with that of certain companies, which we deemed to be reasonably similar to the Company and the Acquiror, respectively;

(6) Compared the proposed financial terms of the transactions contemplated by the Agreement with the financial terms of certain other mergers and acquisitions which we deemed to be relevant;

(7) Considered the pro forma effect of the Merger on the Acquiror;

(8) Reviewed the Agreement; and

(9) Reviewed such other financial studies and analyses and performed such other investigations and took into account such other matters as we deemed necessary, including our assessment of general economic, market and monetary conditions.


In preparing our opinion, we have relied on the accuracy and completeness of all information supplied or otherwise made available to us, discussed with or reviewed by or for us, or publicly available, and we have not assumed any responsibility for independently verifying such information or undertaken an independent evaluation or appraisal of the assets or liabilities of the Company or the Acquiror or been furnished with any such evaluation or appraisal. With respect to the financial forecasts and Expected Synergies furnished by the Company and the Acquiror, we have assumed that they have been reasonably prepared and reflect the best currently available estimates and judgment of the Company's or the Acquiror's management as to the expected future financial performance of the Company or the Acquiror, as the case may be, and the Expected Synergies. We have further assumed that the Merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended.

Our opinion is necessarily based upon market, economic and other conditions as they exist and can be evaluated on, and on the information made available to us as of, the date hereof. We have assumed that in the course of obtaining the necessary regulatory or other consents or approvals (contractual or otherwise) for the Merger, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that will have a material adverse effect on the contemplated benefits of the Merger. We have also assumed that the Merger will be consummated in accordance with the terms of the Agreement without waiver of any material condition.

We are acting as financial advisor to the Acquiror in connection with the Merger and will receive a fee from the Acquiror for our services, a significant portion of which is contingent upon the consummation of the Merger. In addition, the Acquiror has agreed to indemnify us for certain liabilities arising out of our engagement. We have, in the past, provided certain financial advisory and financing services to the Acquiror and to affiliates of its principal shareholder, KKR Associates L.P., and may continue to do so and have received, and may receive, fees for the rendering of such services. In the ordinary course of our business, we may actively trade the Company Shares, as well as the Acquiror Shares, for our own account and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

This opinion is for the use and benefit of the Board of Directors of the Acquiror. Our opinion does not address the merits of the underlying decision by the Acquiror to engage in the Merger and does not constitute a recommendation to any shareholder of the Acquiror as to how such shareholder should vote on the proposed issuance of the Acquiror Shares in the Merger or any matter related thereto.

We are not expressing any opinion herein as to the prices at which the Acquiror Shares will trade following the announcement or consummation of the Merger.

On the basis of, and subject to the foregoing, we are of the opinion that, as of the date hereof, the Exchange Ratio is fair from a financial point of view to the Acquiror.

Very truly yours,

Board of Directors
About.com Inc.
1440 Broadway
New York NY 10018

Dear Sirs:

You have requested our opinion as to the fairness from a financial point of view to the stockholders of About.com Inc. (the "COMPANY") of the consideration to be received by such stockholders pursuant to the terms of the Agreement and Plan of Merger, dated as of October 29, 2000 (the "AGREEMENT"), among Primedia Inc. ("PRIMEDIA"), Abracadabra Acquisition Corporation ("ACQUISITION SUB"), a wholly owned subsidiary of Primedia, and the Company, pursuant to which Acquisition Sub will be merged (the "MERGER") with and into the Company.

Pursuant to the Agreement, each share of common stock, par value $0.001 per share, of the Company ("COMPANY COMMON STOCK") will be converted subject to certain exceptions into the right to receive 2.341 shares of common stock, par value $0.01 per share, of Primedia ("PRIMEDIA COMMON STOCK").

In arriving at our opinion, we have reviewed the draft dated October 29, 2000 of the Agreement. We also have reviewed financial and other information that was publicly available or furnished to us by the Company and Primedia, including information provided to us during discussions with their respective managements of the Company and Primedia. Included in the information provided during discussions with the respective managements were certain financial projections of the Company for the period beginning October 1, 2000 and ending December 31, 2001 prepared by the management of the Company and certain financial projections of Primedia for the period beginning October 1, 2000 and ending December 31, 2005 prepared by the management of Primedia. In addition, we have reviewed the reported price and trading activity for the Company Common Stock and Primedia Common Stock, compared certain financial and securities data for the Company and Primedia with similar information for certain other companies the securities of which are publicly traded, reviewed the financial terms of certain recent business combinations in the Internet content industry specifically and in other industries generally and performed such other financial studies, analyses and investigations as we considered appropriate for the purposes of this opinion.

In rendering our opinion, we have relied upon and assumed the accuracy and completeness of all of the financial and other information that was available to us from public sources, that was provided to us by the Company and Primedia or their respective representatives, or that was otherwise reviewed by us. With respect to the financial projections supplied to us, we have relied on representations of the Company or Primedia, as the case may be, that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of the Company and Primedia, as the case may be, as to the future operating and financial performance of the Company and Primedia, respectively. We have not assumed any responsibility for making an independent evaluation of any assets or liabilities or for making any independent verification of any of the information reviewed by us. We have relied as to certain legal matters on advice of counsel to the Company.

Our opinion is necessarily based on economic, market, financial and other conditions as they exist on, and on the information made available to us as of, the date of this letter. It should be understood that, although subsequent developments may affect the conclusion reached in this opinion, we do not have any obligation to update, revise or reaffirm this opinion. We are expressing no opinion herein as


to what the value of Primedia Common Stock will be when issued to the Company's stockholders or as to the prices at which Primedia Common Stock will actually trade at any time. Our opinion does not address the relative merits of the Merger and any other business strategies being considered by the Board of Directors of the Company. In addition, it is understood that this letter is solely for the information of the Board of Directors of the Company in connection with its consideration of the Merger and that our opinion does not constitute a recommendation to any stockholder as to how such stockholder should vote on the Merger. Donaldson, Lufkin, & Jenrette Securities Corporation ("DLJ") is acting as financial advisor to the Company in connection with the Merger and will receive a fee for its services, a significant portion of which is contingent upon the consummation of the Merger. DLJ, as part of its investment banking services, is regularly engaged in the valuation of businesses and securities in connection with mergers, acquisitions, underwritings, sales and distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. DLJ has performed investment banking and other services for the Company in the past, including lead managing a follow-on offering in October 1999 and has been compensated for such services. DLJ has also performed investment banking and other services for affiliates of Kohlberg Kravis Roberts & Co., an affiliate of Primedia, including but not limited to M&A advisory, equity and debt financings and has been compensated for such services. In the ordinary course of business, DLJ and its affiliates may actively trade the debt and equity securities of the Company and Primedia for its own and such affiliates' accounts and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

Based upon the foregoing and such other factors as we deem relevant, we are of the opinion that the consideration to be received by holders of Company Common Stock pursuant to the Agreement is fair to such holders from a financial point of view.

Very truly yours,

AGREEMENT AND PLAN OF MERGER

AGREEMENT AND PLAN OF MERGER, dated as of October 29, 2000 (the "AGREEMENT"), among PRIMEDIA Inc., a Delaware corporation ("PARENT"), Abracadabra Acquisition Corporation, a Delaware corporation and a direct wholly owned subsidiary of Parent ("SUB"), and About.com, Inc., a Delaware corporation (the "COMPANY").

WHEREAS, the Boards of Directors of Parent and Sub and the Company have declared this Agreement to be advisable, and the Boards of Directors of Parent, Sub and the Company have each approved the merger of Sub with and into the Company and the Company becoming a wholly owned direct subsidiary of Parent (the "MERGER") in accordance with the General Corporation Law of the State of Delaware ("DGCL") upon the terms and subject to the conditions set forth herein;

WHEREAS, certain stockholders of Parent holding not less than 70% of the outstanding voting securities of Parent have entered into a voting agreement, dated as of the date hereof (the "PARENT VOTING AGREEMENT"), pursuant to which they have agreed, among other things, to consent to the issuance of Parent Common Stock (as defined below) in the Merger;

WHEREAS, concurrently with the execution and delivery of this Agreement and as an inducement to the willingness of Parent and Sub to enter into this Agreement, certain holders of shares of common stock, par value $.001 per share (the "COMPANY COMMON STOCK"), of the Company have each entered into a voting agreement, dated as of the date hereof (the "SHAREHOLDER VOTING AGREEMENT"), pursuant to which such holders have agreed to vote their shares of Company Common Stock in the manner set forth therein; and

WHEREAS, for Federal income tax purposes, it is intended that the Merger shall qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the "CODE");

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, Parent, Sub and the Company hereby agree as follows:

ARTICLE I

THE MERGER

Section 1.1. THE MERGER. Upon the terms and subject to the conditions of this Agreement and in accordance with the DGCL, at the Effective Time (as defined in Section 1.2), Sub shall be merged with and into the Company. As a result of the Merger, the separate corporate existence of Sub shall cease and the Company shall continue as the surviving corporation of the Merger (the "SURVIVING CORPORATION"). At Parent's election, the Merger may alternatively be structured so that any direct wholly owned subsidiary of Parent may be substituted for Sub as a constituent corporation in the Merger. In the event of such an election, the parties agree to execute an appropriate amendment to this Agreement in order to reflect such election.

Section 1.2. EFFECTIVE TIME. As soon as practicable after the satisfaction or waiver of the conditions set forth in Article VI, the parties hereto shall cause the Merger to be consummated by filing a certificate of merger (the "CERTIFICATE OF MERGER") with the Secretary of State of the State of Delaware, in such form as required by and executed in accordance with the relevant provisions of the DGCL (the date and time of the filing of the Certificate of Merger with the Secretary of State of the State of Delaware (or such later time as is specified in the Certificate of Merger and agreed upon by the parties hereto) being the "EFFECTIVE TIME").

D-1

Section 1.3. EFFECTS OF THE MERGER. The Merger shall have the effects set forth in the applicable provisions of the DGCL. Without limiting the generality of the foregoing and subject thereto, at the Effective Time all the property, rights, privileges, immunities, powers and franchises of the Company and Sub shall vest in the Surviving Corporation, and all debts, liabilities and duties of the Company and Sub shall become the debts, liabilities and duties of the Surviving Corporation.

Section 1.4. CERTIFICATE OF INCORPORATION; BY-LAWS. (a) At the Effective Time and without any further action on the part of the Company and Sub, the Restated Certificate of Incorporation of the Company (the "CERTIFICATE OF INCORPORATION") as in effect immediately prior to the Effective Time shall be the Restated Certificate of Incorporation of the Surviving Corporation until thereafter and further amended as provided therein and under the DGCL.

(b) At the Effective Time and without any further action on the part of the Company and Sub, the Amended and Restated By-Laws of the Company (the "BY-LAWS") shall be the Amended and Restated By-Laws of the Surviving Corporation and thereafter may be amended or repealed in accordance with their terms or the Certificate of Incorporation of the Surviving Corporation and as provided by law.

Section 1.5. DIRECTORS AND OFFICERS. The directors of Sub immediately prior to the Effective Time shall be the initial directors of the Surviving Corporation, each to hold office in accordance with the Certificate of Incorporation and By-Laws of the Surviving Corporation, and the officers of the Company immediately prior to the Effective Time shall be the initial officers of the Surviving Corporation, in each case until their respective successors are duly elected or appointed (as the case may be) and qualified.

Section 1.6. CONVERSION OF SECURITIES. At the Effective Time, by virtue of the Merger and without any action on the part of Sub, the Company or the holders of any of the following securities:

(a) Subject to Section 1.8, each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than shares of Company Common Stock to be canceled in accordance with Section 1.6(b) hereof) shall be converted into 2.3409 (the "EXCHANGE RATIO") fully paid and nonassessable shares of Common Stock, par value $0.01 per share (the "PARENT COMMON STOCK"), of Parent (the "MERGER CONSIDERATION"). As of the Effective Time, all such shares of Company Common Stock shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and each holder of a certificate representing any such shares of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration and any cash in lieu of fractional shares of Parent Common Stock to be issued or paid in consideration therefor upon surrender of such certificate in accordance with Section 1.9, without interest.

(b) Each share of Company Common Stock that is (i) held in the treasury of the Company or (ii) owned by Parent immediately prior to the Effective Time shall be cancelled and retired without any conversion thereof and no payment or distribution shall be made with respect thereto.

(c) Each share of common stock of Sub issued and outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and non-assessable share of common stock of the Surviving Corporation and shall thereafter constitute all of the issued and outstanding capital stock of the Surviving Corporation.

Section 1.7. TREATMENT OF EMPLOYEE OPTIONS AND STOCK PURCHASE PLAN.

(a) Prior to the Effective Time, the Board of Directors of the Company (or, if appropriate, any Committee thereof) and the Board of Directors of Parent (or, if appropriate, any Committee thereof) shall adopt appropriate resolutions and take all other actions necessary to provide that as of the Effective Time all outstanding stock options of the Company (the "COMPANY STOCK RIGHTS")

D-2

heretofore granted under any stock option plan of the Company or its acquired subsidiaries (the "STOCK PLANS") and which are outstanding immediately prior to the Effective Time shall be assumed by Parent and be deemed to constitute an option to purchase shares of Parent Common Stock or, in the case of Company Stock Rights which are in the form of restricted stock, shares of restricted Parent Common Stock (collectively, "NEW STOCK RIGHTS") in an amount and, if applicable, at an exercise price determined as provided below:

(i) The number of shares of Parent Common Stock to be subject to the New Stock Rights shall be equal to the product of the number of shares of Company Common Stock remaining subject (as of immediately prior to the Effective Time) to the original Company Stock Right and the Exchange Ratio, PROVIDED that any fractional shares of Parent Common Stock resulting from such multiplication shall be rounded down to the nearest share; and

(ii) The exercise price per share of Parent Common Stock under the New Stock Right shall be equal to the exercise price per share of the Company Common Stock under the original Company Stock Right divided by the Exchange Ratio, PROVIDED that such exercise price shall be rounded down to the nearest cent.

The adjustment provided herein with respect to any options which are "incentive stock options" (as defined in Section 422 of the Code) shall be and is intended to be effected in a manner which is consistent with
Section 424(a) of the Code. Except as may be required by the terms of the Automatic Option Grant Program under the 1998 Stock Option/Stock Issuance Plan or any grants thereunder as of the date hereof to directors, the Company shall not accelerate the vesting, or otherwise amend the terms, of any unvested Company Stock Rights under any of the Stock Plans. After the Effective Time, each New Stock Right shall be exercisable and shall vest upon the same terms and conditions as were applicable to the related Company Stock Right immediately prior to the Effective Time except that all references to the Company shall be deemed to be references to the Parent.

(b) Immediately prior to the Effective Time, pursuant to the terms of the Company's 1999 Employee Stock Purchase Plan (the "ESPP"), each outstanding purchase right under the ESPP shall be exercised for the purchase of Company Common Stock at the price per share set forth in the ESPP. The Company Common Stock purchased under the ESPP shall be considered issued and outstanding immediately prior to the Effective Time and shall be converted pursuant to Section 1.6 hereof. In addition, prior to the Effective Time, the Company shall amend the ESPP to provide for (i) its continuation from and after the Effective Time and (ii) a new offering period to commence from and after the Effective Time and to terminate immediately prior to the start of the next succeeding offering period under the PRIMEDIA Employee Stock Purchase Plan for which participants in the ESPP are eligible to particpate.

(c) The Company shall ensure that following the Effective Time no holder of a Company Stock Right or any participant in any Stock Plans shall have any right thereunder to acquire capital stock of the Company, Sub, or the Surviving Corporation. The Company will take all reasonable steps to ensure that, immediately following the Effective Time, none of Sub, the Company, the Surviving Corporation or any of their respective subsidiaries is or will be bound by any Company Stock Rights, other options, warrants, rights or agreements which would entitle any person, other than Sub or its affiliates, to own any capital stock of the Company, Sub, the Surviving Corporation or any of their respective subsidiaries or to receive any payment in respect thereof.

(d) In connection with the issuance of New Stock Rights and the assumption of the ESPP, Parent shall (i) reserve for issuance the aggregate number of shares of Parent Common Stock that will become subject to New Stock Rights and the ESPP pursuant to this Section 1.7 from and after the Effective Time, upon exercise of New Stock Rights and the purchase rights under the ESPP, (ii) make available for issuance all shares of Parent Common Stock covered thereby, subject to the

D-3

terms and conditions applicable thereto, and (iii) if necessary, as soon as reasonably practicable following the Effective Time, file a registration statement on Form S-8 covering the shares to be issued upon exercise of the New Stock Rights and the purchase rights under the ESPP.

Section 1.8. FRACTIONAL INTERESTS. No certificates or scrip representing fractional shares of Parent Common Stock shall be issued in connection with the Merger, and such fractional interests will not entitle the owner thereof to any rights of a stockholder of Parent. In lieu of any such fractional interests, each holder of shares of Company Common Stock exchanged pursuant to Section 1.6(a) who would otherwise have been entitled to receive a fraction of a share of Parent Common Stock (after taking into account all shares of Company Common Stock then held of record by such holder) shall receive cash (without interest) in an amount equal to the product of such fractional part of a share of Parent Common Stock multiplied by the closing price of a share of Parent Common Stock on the NYSE as reported by The Wall Street Journal (or if not reported thereby, any other authoritative source) on the Closing Date (as defined in Section 1.12), rounded down to the nearest cent.

Section 1.9. SURRENDER OF SHARES OF COMPANY COMMON STOCK; STOCK TRANSFER BOOKS. (a) Prior to the Closing Date, Sub shall designate a bank or trust company to act as agent for the holders of shares of Company Common Stock in connection with the Merger (the "EXCHANGE AGENT") to receive the shares of Parent Common Stock (and any cash payable in lieu of any fractional shares of Parent Common Stock) to which holders of shares of Company Common Stock shall become entitled pursuant to Sections 1.6(a) and 1.8. When and as needed, Parent or Sub will make available to the Exchange Agent sufficient shares of Parent Common Stock and cash to make all exchanges pursuant to Section 1.9(b).

(b) Promptly after the Effective Time, the Surviving Corporation shall cause to be mailed to each record holder, as of the Effective Time, of an outstanding certificate or certificates which immediately prior to the Effective Time represented shares of Company Common Stock (the "CERTIFICATES"), a form of letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of Parent Common Stock therefor and for cash payable in lieu of any fractional shares of Parent Common Stock. Upon surrender to the Exchange Agent of a Certificate, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Certificate shall be entitled to receive in exchange therefor, (i) a certificate representing that number of whole shares of Parent Common Stock which such holder has the right to receive pursuant to the provisions of
Section 1.6(a) and (ii) cash in lieu of any fractional shares of Parent Common Stock to which such holder is entitled pursuant to Section 1.8, after giving effect to any required tax withholdings, and the Certificate so surrendered shall forthwith be cancelled. If the exchange of certificates representing shares of Parent Common Stock is to be made to a person other than the person in whose name the surrendered Certificate is registered, it shall be a condition of exchange that the Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the person requesting such exchange shall have paid any transfer and other taxes required by reason of the exchange of certificates representing shares of Parent Common Stock to a person other than the registered holder of the Certificate surrendered or shall have established to the satisfaction of the Surviving Corporation that such tax either has been paid or is not applicable.

(c) At any time following six months after the Effective Time, the Surviving Corporation shall be entitled to require the Exchange Agent to deliver to it any shares of Parent Common Stock (and any cash payable in lieu of any fractional shares of Parent Common Stock) which had been made available to the Exchange Agent and which have not been disbursed to holders of Certificates, and thereafter such holders shall be entitled to look to the Surviving Corporation

D-4

(subject to abandoned property, escheat or other similar laws) only as general creditors thereof with respect to the shares of Parent Common Stock (and any cash payable in lieu of any fractional shares of Parent Common Stock) payable upon due surrender of their Certificates. Notwithstanding the foregoing, none of the Surviving Corporation, Parent or the Exchange Agent shall be liable to any holder of a Certificate for shares of Parent Common Stock (and any cash payable in lieu of any fractional shares of Parent Common Stock) delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

(d) At the Effective Time, the stock transfer books of the Company shall be closed and thereafter there shall be no further registration of transfers of shares of Company Common Stock on the records of the Company. From and after the Effective Time, the holders of Certificates evidencing ownership of shares of Company Common Stock outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such shares of Company Common Stock except as otherwise provided for herein or by applicable law.

(e) No dividends or other distributions declared or made after the Effective Time with respect to shares of Parent Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the whole shares of Parent Common Stock it is entitled to receive and no cash payment in lieu of fractional interests shall be paid pursuant to Section 1.8 until the holder of such Certificate shall surrender such Certificate in accordance with the provisions of this Agreement. Upon such surrender, there shall be paid to the person in whose name the certificates representing such whole shares of Parent Common Stock shall be issued, any dividends or distributions with respect to such shares of Parent Common Stock which have a record date after the Effective Time and shall have become payable between the Effective Time and the time of such surrender. In no event shall the person entitled to receive such dividends or distributions be entitled to receive interest thereon.

(f) If, at any time after the Effective Time, the Surviving Corporation shall consider or be advised that any deeds, bills of sale, assignments, assurances or any other actions or things are necessary or desirable to vest, perfect or confirm of record or otherwise in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of either Sub or the Company acquired or to be acquired by the Surviving Corporation as a result of, or in connection with, the Merger or otherwise to carry out this Agreement, the officers of the Surviving Corporation shall be authorized to execute and deliver, in the name and on behalf of each of Sub and the Company or otherwise, all such deeds, bills of sale, assignments and assurances and to take and do, in such names and on such behalves or otherwise, all such other actions and things as may be necessary or desirable to vest, perfect or confirm any and all right, title and interest in, to and under such rights, properties or assets in the Surviving Corporation or otherwise to carry out the purposes of this Agreement.

Section 1.10. LOST CERTIFICATES. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the holder claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such holder of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed Certificate the applicable Merger Consideration with respect to the shares of Company Common Stock formerly represented thereby, any cash in lieu of fractional shares of Parent Common Stock and unpaid dividends and distributions on shares of Parent Common Stock deliverable in respect thereof pursuant to this Agreement.

Section 1.11. WITHHOLDING RIGHTS. Each of the Surviving Corporation and Parent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as it is required to deduct and withhold

D-5

with respect to the making of such payment under the Code and the rules and regulations promulgated thereunder, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by the Surviving Corporation or Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by the Surviving Corporation or Parent, as the case may be.

Section 1.12. CLOSING AND CLOSING DATE. Unless this Agreement shall have been terminated and the transactions herein contemplated shall have been abandoned pursuant to the provisions of Section 7.1, the closing (the "CLOSING") of this Agreement shall take place (a) at 10:00 a.m. (New York time) on the second business day after all of the conditions to the respective obligations of the parties set forth in Article VI hereof shall have been satisfied or waived or (b) at such other time and date as Parent and the Company shall agree (such date and time on and at which the Closing occurs being referred to herein as the "CLOSING DATE"). The Closing shall take place at such location as Parent and the Company shall agree.

ARTICLE II

REPRESENTATIONS AND WARRANTIES OF THE COMPANY

The Company hereby represents and warrants to Parent and Sub that, except as set forth in the corresponding sections or subsections of the Disclosure Schedule delivered by the Company to Parent and Sub prior to the execution of this Agreement (the "COMPANY DISCLOSURE SCHEDULE") or in any other section or subsection of the Company Disclosure Schedule if it is reasonably apparent that such disclosure applies:

Section 2.1. ORGANIZATION AND QUALIFICATION. Each of the Company and each of its subsidiaries is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has the requisite corporate power and authority and any necessary governmental approvals to own, lease and operate its properties and to carry on its business as it is now being conducted, except where the failure to have such power, authority and governmental approvals could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect (as defined below). Each of the Company and each of its subsidiaries is duly qualified or licensed as a foreign corporation to do business, and is in good standing, in each jurisdiction where the character of its properties owned, leased or operated by it or the nature of its activities makes such qualification or licensing necessary, except for such failures to be so duly qualified or licensed or in good standing which could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. When used in this Article II or otherwise in connection with the Company or any of its subsidiaries, the term "MATERIAL ADVERSE EFFECT" means any change or effect that would be materially adverse to the business, properties, assets, condition (financial or otherwise) or results of operations of the Company and its subsidiaries taken as a whole or that would materially impair the ability of the Company to perform its obligations hereunder; PROVIDED that none of the following shall be taken into account in determining whether there has been or could be a Material Adverse Effect: (w) any employee attrition after the date hereof; (x) any change arising from the public announcement of the Merger and the other transactions contemplated by this Agreement; (y) any change in the market price or trading volume of the Company Common Stock after the date hereof; or (z) any adverse effect on the Company attributable solely to conditions affecting the business to consumer Internet industry, the United States economy as a whole or foreign economies in any locations where the Company or any of its subsidiaries has material operations or sales (and not having a materially disproportionate effect on the Company).

Section 2.2. CERTIFICATE OF INCORPORATION AND BY-LAWS. The Company has heretofore furnished or made available to Parent a complete and correct copy of the Certificate of Incorporation and the By-

D-6

No shares of preferred stock of the Company are outstanding or held in the treasury of the Company. Except as set forth above or in Section 2.3(a) of the Company Disclosure Schedule, there are outstanding (A) no shares of capital stock or other voting securities (including indebtedness having the right to vote) of the Company, (B) no securities of the Company convertible into or exchangeable for shares of capital stock or voting securities (including indebtedness having the right to vote) of the Company, (C) no options, warrants or other rights to acquire from the Company, and no obligation of the Company to issue, any capital stock, voting securities (including indebtedness having the right to vote) or securities convertible into or exchangeable for capital stock or voting securities (including indebtedness having the right to vote) of the Company and (D) no equity equivalents, interests in the ownership or earnings of the Company or other similar rights (collectively, "COMPANY SECURITIES"). Except pursuant to the Stock Plans and the Company Securities issued thereunder, there are no outstanding obligations of the Company or any of its subsidiaries to repurchase, redeem or otherwise acquire any Company Securities and there is no voting trust or other agreement or understanding to which the Company or any of its subsidiaries is a party or is bound with respect to the voting of the capital stock of the Company of any of its subsidiaries.

D-28

account all legal, financial, regulatory and other aspects of the proposal and the person making the proposal (including any break-up fees, expense reimbursement provisions and conditions to consummation), (i) would, if consummated, result in a transaction that is more favorable to all of the Company's stockholders (in their capacities as stockholders), from a financial point of view, than the transactions contemplated by this Agreement and (ii) is reasonably capable of being completed (PROVIDED that for purposes of this definition of "Superior Proposal," the term Acquisition Proposal shall have the meaning assigned to such term in this Section 5.4, except that the reference to "15%" in the definition of "Acquisition Proposal" shall be deemed to be a reference to "51%" and "Acquisition Proposal" shall only be deemed to refer to a transaction involving the Company, and the reference to "assets" (including the shares of any subsidiary of the Company) shall refer to the assets of the Company and its subsidiaries, taken as a whole, and not the assets of any of the subsidiaries alone).

Section 5.5. EMPLOYEE BENEFITS MATTERS.

(b) Parent shall, for the period ending on December 31, 2001, maintain (or cause the Surviving Corporation to maintain) employee benefit plans (other than with respect to equity-based compensation, except as contemplated by Section 1.7(b)) for the benefit of each employee of the Company or its subsidiaries who continues employment with the Surviving Corporation as of the Effective Time that are no less favorable in the aggregate to the Plans in effect immediately prior to the Effective Time with respect to each such employee; provided, that nothing herein shall require Parent and/or the Surviving Corporation to continue to maintain any Plan or grant any such employee any equity-based compensation in the Surviving Corporation or Parent. For purposes of determining eligibility to participate, eligibility for benefit forms and subsidies and the vesting of benefits under such plans (without duplication of benefits as a result thereof), the Surviving Corporation shall give effect to years of service with the Company and its subsidiaries in respect of years of service for which credit was given by the Company and its subsidiaries. No employee electing coverage under the medical insurance plans of the Surviving Corporation shall be excluded from coverage thereunder (for such employee and any person covered by virtue of such employee's employment) on the basis of a pre-existing condition that was not also excluded under the Company's medical insurance plan.

Section 5.6. DIRECTORS' AND OFFICERS' INDEMNIFICATION; INSURANCE.

D-29

been heretofore delivered to Parent), so long as the annual premium therefor would not be in excess of 150% of the last annual premium paid prior to the date of this Agreement (the "COMPANY'S CURRENT PREMIUM"). If such premiums for such insurance would at any time exceed 150% of the Company's Current Premium, then the Surviving Corporation shall cause to be maintained policies of insurance that in the Surviving Corporation's good faith determination, provide the maximum coverage available at an annual premium equal to 150% of the Company's Current Premium.

Section 5.7. NOTIFICATION OF CERTAIN MATTERS. The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, of

In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and directors of each party to this Agreement shall use their reasonable best efforts to take all such necessary action. In the event that a suit or objection is instituted by any person or governmental authority challenging this Agreement and the transactions contemplated hereby as violative of applicable competition and antitrust laws, each of Parent and the Company shall use their reasonable best efforts to resist or resolve such suit or objection. Notwithstanding the foregoing, in connection with any such objection or suit instituted by such person or governmental authority (including, but not limited to, the Federal Trade Commission or the Antitrust Division of the Department of Justice), neither Parent nor Sub shall be required to provide any undertakings or agree to any condition that could reasonably be expected to result in a substantial detriment to Parent's or the Company's business or results of operations (a "SUBSTANTIAL DETRIMENT").

WHEREAS, each Shareholder beneficially owns the number of shares of common stock, par value $0.001 per share, of the Company set forth below such Shareholder's name on the signature page hereof (all such shares, together with any other shares of capital stock of the Company such Shareholder acquires after the date hereof, including, without limitation, as a result of a stock dividend, stock split, recapitalization, combination, reclassification, exchange, or change of such shares, or upon exercise or conversion of any securities, the "SHARES");

WHEREAS, simultaneously with the execution and delivery hereof, Parent, Merger Sub and the Company have entered into an Agreement and Plan of Merger (the "MERGER AGREEMENT"; capitalized terms used herein and not defined shall have the meanings set forth in the Merger Agreement), dated as of the date hereof, which Merger Agreement has been approved by the Board of Directors of the Company, and has been approved by the Boards of Directors of Parent and Merger Sub. The directors of the Company unanimously voted in favor of the adoption of the Merger Agreement and the recommendation that shareholders of the Company approve the merger of Merger Sub with and into the Company (the "MERGER") as contemplated by the Merger Agreement; and

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the parties hereby agree as follows

Section 1. REPRESENTATIONS AND WARRANTIES OF THE SHAREHOLDERS. Each Shareholder severally represents and warrants to Parent and Merger Sub as follows:

(b) This Agreement has been duly and validly executed and delivered by such Shareholder and, assuming this Agreement constitutes a valid and binding obligation of Parent and Merger Sub, constitutes a legal, valid and binding obligation of such Shareholder enforceable against such Shareholder in accordance with its terms (except insofar as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' rights generally or by principles governing the availability of equitable remedies).

(c) The execution, delivery and performance by such Shareholder of this Agreement and the consummation of the transactions contemplated hereby do not and will not (i) contravene or conflict with its organizational documents; (ii) contravene or conflict with or constitute a violation of any provision of any law, regulation, judgment, injunction, order or decree binding upon or applicable to such Shareholder or any of its properties; or
(iii) conflict with, or result in the breach or termination of or constitute a default (with or without the giving of notice or the lapse of time or both) under, or give rise to any right of termination, cancellation, or loss of any benefit to which such Shareholder is entitled under any provision of any agreement, contract, license or other instrument binding upon such Shareholder or any of its properties, or allow the acceleration of the performance of any obligation of such Shareholder under any indenture, mortgage deed of trust,


lease, license, contract, instrument or other agreement to which such Shareholder is a party or by which such Shareholder, its assets or properties is subject or bound, other than such contraventions, conflicts, violations, breaches, defaults or other occurrences that would not reasonably be expected to prevent, delay or impair such Shareholder's ability to consummate the transactions contemplated by this Agreement.

(e) As of the date hereof, there is no action, suit, claim, investigation or proceeding pending or, to the knowledge of such Shareholder, threatened against such Shareholder or its properties before any court or arbitrator or any governmental authority which challenges or seeks to prevent, enjoin, alter or delay the Merger or any of the other transactions contemplated hereby or by the Merger Agreement. As of the date hereof, such Shareholder is not, and none of its properties is, subject to any order, writ, judgment, injunction, decree, determination or award which would prevent, delay or impair the consummation of the transactions contemplated hereby.

Section 2. AGREEMENT TO VOTE; PROXY.

(a) Each Shareholder agrees with, and covenants to, Parent and Merger Sub as follows:

(i) At any meeting of shareholders of the Company called to vote upon the Merger, the Merger Agreement or the other transactions contemplated by the Merger Agreement or at which a vote, consent or other approval with respect to the Merger, the Merger Agreement or the other transactions contemplated by the Merger Agreement is sought, such Shareholder shall vote (or cause to be voted) or shall consent, execute a consent or cause to be executed a consent in respect of the Shares held by such Shareholder in favor of the Merger, the execution and delivery by the Company of the Merger Agreement and the approval of the terms thereof and each of the other transactions contemplated by the Merger Agreement.

(ii) At any meeting of shareholders of the Company or at any adjournment thereof or in any other circumstances upon which their vote, consent or other approval is sought, such Shareholder shall vote (or cause to be voted) the Shares held by such Shareholder against (A) any Acquisition Proposal or (B) any amendment of the Company's Certificate of

E-2

Incorporation or By-laws which amendment would in any manner prevent or materially impede, interfere with or delay the Merger, the Merger Agreement or any of the other transactions contemplated by the Merger Agreement.

(b) Each Shareholder hereby grants to, and appoints, Beverly Chell and Charles McCurdy and any other individual who is designated by Parent, until the termination of this Agreement pursuant to Section 12, an irrevocable proxy, coupled with an interest, and attorney-in-fact (with full power of substitution), for and in the name, place and stead of such Shareholder, with respect to the Shares held by such Shareholder, to vote the Shares held by such Shareholder, or grant or execute a consent or approval, in complete discretion of Parent or Merger Sub, a the case may be, at any meeting of shareholders of the Company or at any adjournment thereof or in any other circumstances upon which their vote, consent or other approval is sought in accordance with paragraph (a) of this Section 2.

Each Shareholder hereby irrevocably waives any rights of appraisal or rights to dissent from the Merger that such Shareholder may have. Each Shareholder agrees, and shall use reasonable efforts to cause its affiliates to agree, to exercise any rights that such Shareholder or any of such affiliates may have to cause any shareholders of the Company, to vote any shares held by such shareholder in favor of the Merger and to waive any rights of appraisal or rights of dissent from the Merger that such shareholder may have. Any purported transfer in violation of the foregoing shall be null and void.

Section 4. NO SOLICITATIONS. Subject to Section 16 below, each Shareholder and its affiliates (other than the Company and its subsidiaries) will immediately cease any existing discussions or negotiations with any third parties conducted on or prior to the date hereof with respect to any Acquisition Proposal.

(ii) Parent and Merger Sub and their successors and permitted assigns. Each Shareholder agrees that this Agreement and the obligations of such Shareholder hereunder shall attach to such Shareholder's Shares and shall be binding upon any person or entity to which legal or beneficial ownership of such Shares shall pass, by the laws of inheritance.

Section 9. SEVERABILITY. The provisions of this Agreement shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity and enforceability of the other provisions hereof.

Section 17. NO WAIVER. No failure or delay by Parent or Merger Sub to assert any of its rights under this Agreement or otherwise shall constitute a waiver of such rights. No single or partial exercise of any right, remedy, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege. Any waiver shall be effective only in the specific instance and for the specific purpose for which given and shall not constitute a waiver to any subsequent or other exercise of any right, remedy, power or privilege hereunder.

Reference is made to Section 102(b)(7) of the Delaware General Corporation Law (the "DGCL"), which enables a corporation in its original certificate of incorporation or an amendment thereto to eliminate or limit the personal liability of a director for violations of the director's fiduciary duty, except (i) for any breach of the director's duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (ii) pursuant to Section 174 of the DGCL (providing for liability of directors for unlawful payment of dividends or unlawful stock purchase or redemptions) or (iv) for any transaction from which a director derived an improper personal benefit.

Reference also is made to Section 145 of the DGCL, which provides that a corporation may indemnify any persons, including officers and directors, who are, or are threatened to be made, parties to any threatened, pending or completed legal action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person was an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorney's fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such officer, director, employee or agent acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation's best interest and, for criminal proceedings, had no reasonable cause to believe that his conduct was unlawful. A Delaware corporation may indemnify officers and directors in an action by or in the right of the corporation under the same conditions, except that no indemnification is permitted without judicial approval if the officer or director is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses that such officer or director actually and reasonably incurred.

Article 8 of the Certification of Incorporation of PRIMEDIA provides that except as provided under the Delaware General Corporation Law, directors of PRIMEDIA shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duties as a director. Article 4 of the by-laws of PRIMEDIA provides for indemnification of the officers and directors of PRIMEDIA to the fullest extent permitted by applicable law and provides for the advancement of expenses.

ITEM 22. UNDERTAKINGS.

The undersigned Registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment or prospectus supplement to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with

II-3


or furnished to the Commission by the Registrant pursuant to Section 13 or
Section 15(d) of the Securities Exchange Act that are incorporated by reference in the registration statement;

(2) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering;

(4) that, for purposes of determining any liability under the Securities Act, each filing of Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof;

(5) to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request;

(6) to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective;

(7) that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form; and

(8) that every prospectus (i) that is filed pursuant to paragraph (7) immediately preceding, or (ii) that purports to meet the requirements of
Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

II-4


SIGNATURES

Pursuant to the requirements of the Securities Act, the Registrant has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of New York, State of New York, on the 17th of January, 2001.

Re: Agreement and Plan of Merger among PRIMEDIA Inc., Abracadabra Acquisition Corporation and About.com, Inc., dated as of October 29, 2000, as amended January 2, 2001

Ladies and Gentlemen:

We have acted as special counsel to PRIMEDIA Inc. ("Parent"), a Delaware corporation, in connection with the proposed merger (the "Merger") of Abracadabra Acquisition Corporation ("Merger Sub"), a Delaware corporation and a direct wholly-owned subsidiary of Parent, with and into About.com, Inc. ("Company"), a Delaware corporation, with the separate corporate existence of Merger Sub ceasing and Company continuing as the surviving corporation. The Merger will be consummated pursuant to the Agreement and Plan of Merger dated as of October 29, 2000, as amended or supplemented through the date hereof, by and among Parent, Merger Sub and Company (the "Merger Agreement"). For purposes of this opinion, capitalized terms used and not otherwise defined herein shall have the meaning ascribed thereto in the Merger Agreement. This opinion is being delivered in connection with Parent's Registration Statement on Form S-4 relating to the proposed Merger pursuant to the Merger Agreement (the "Registration Statement") to which this opinion appears as an exhibit. In acting as counsel to Parent in connection with the Merger, we have, in preparing our opinion, as hereinafter set forth, participated in the preparation of the Merger Agreement and the preparation and filing of the Registration Statement.

You have requested that we render the opinion set forth below. In rendering such opinion, we have assumed with your consent that (i) the Merger will be effected in accordance with the Merger Agreement, (ii) the statements concerning the Merger set forth in the Merger Agreement and the Registration Statement are true, complete and correct and will remain true, complete and correct at all times up to and including the Effective Time, (iii) the representations made by Parent, Merger Sub and Company in their respective letters delivered to us for purposes of this opinion (the "Representation Letters") are true, complete and correct and will remain true, complete and correct at all times up to and including the Effective Time, and (iv) any representations made in the Representation Letters "to the best knowledge of" or similarly qualified are true, correct and complete without such qualification. We have also assumed that the parties have complied with and, if applicable, will continue to comply with, the covenants contained in the Merger Agreement. We have examined the documents referred to above and the originals, or duplicates or certified or conformed copies, of such records, documents, certificates or other instruments and made such other inquiries as in our judgment are necessary or appropriate to enable us to render the opinion set forth below. We have not, however, undertaken any independent investigation of any factual matter set forth in any of the foregoing.

If the Merger is effected on a factual basis different from that contemplated in the Merger Agreement and the Registration Statement the opinion expressed herein may be inapplicable. Our opinion is based on the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations, administrative interpretations, and judicial precedents as of the date hereof. If there is any subsequent change in the applicable law or regulations, or if there are subsequently any new applicable administrative or judicial interpretations of the law or regulations, the opinion expressed herein may become inapplicable.


Based on and subject to the foregoing, the discussion contained in the Registration Statement under the caption "THE MERGER--Material United States Federal Income Tax Consequences of the Merger," constitutes, in all material respects, an accurate summary of the United States federal income tax matters described therein.

We express our opinion herein only as to those matters specifically set forth above and no opinion should be inferred as to the tax consequences of the Merger under any state, local or foreign law, or with respect to other areas of United States federal taxation. We are members of the Bar of the State of New York, and we do not express any opinion herein concerning any law other than the federal law of the United States.

We hereby consent to the filing of this opinion as Exhibit 8.1 to the Registration Statement and to the references to our firm name therein.

January 17, 2001

About.com, Inc.
1440 Broadway, 19th Floor
New York, New York 10018

Ladies and Gentlemen:

This opinion is being delivered to you in connection with (i) the Agreement and Plan of Merger (the "Agreement") dated as of October 29, 2000 between PRIMEDIA Inc., a Delaware corporation ("Parent"), Abracadabra Acquisition Corporation, a Delaware corporation and a wholly owned subsidiary of Parent ("Merger Sub"), and About.com, Inc., a Delaware corporation ("Target"), and
(ii) the preparation and filing with the Securities and Exchange Commission of a Form S-4 Registration Statement relating to the Merger (the "Registration Statement"). Pursuant to the Agreement, Merger Sub will merge with and into Target (the "Merger"), and Target will become a wholly owned subsidiary of Parent.

Except as otherwise provided, capitalized terms referred to herein have the meanings set forth in the Agreement. All section references, unless otherwise indicated, are to the Internal Revenue Code of 1986, as amended (the "Code").

We have acted as legal counsel to Target in connection with the Merger. As such, and for the purpose of rendering this opinion, we have examined and are relying upon (without any independent investigation or review thereof) the truth and accuracy, at all relevant times, of the statements, covenants, representations and warranties contained in the following documents (including all schedules and exhibits thereto):

1. The Agreement;

2. The Registration Statement; and

3. Such other instruments and documents related to Parent, Target, Merger Sub and the Merger as we have deemed necessary or appropriate.

In connection with rendering this opinion, we have assumed or obtained representations (and are relying thereon, without any independent investigation or review thereof) that:

A. Original documents submitted to us (including signatures) are authentic, documents submitted to us as copies conform to the original documents, and there has been (or will be by the Effective Time) due execution and delivery of all documents where due execution and delivery are prerequisites to the effectiveness thereof; and

B. The Merger will be consummated in accordance with the Agreement without any waiver or breach of any material provision thereof, and the Merger will be effective under applicable state law.

Based on our examination of the foregoing items and subject to the assumptions, exceptions, limitations and qualifications set forth herein, we are of the opinion that the statements regarding United States federal income tax consequences set forth in the Registration Statement under the heading "Material United States Federal Income Tax Consequences of the Merger," insofar as they constitute statements of law or legal conclusions, are correct in all material respects. We express no opinion as to any federal, state or local, foreign or other tax consequences, other than as set forth in the Registration Statement under the heading "Material United States Federal Income Tax Consequences of the Merger."


In addition to the assumptions and representations described above, this opinion is subject to the exceptions, limitations and qualifications set forth below.

(1) This opinion represents and is based upon our best judgment regarding the application of federal income tax laws arising under the Code, existing judicial decisions, administrative regulations and published rulings and procedures. Our opinion is not binding upon the Internal Revenue Service or the courts, and there is no assurance that the Internal Revenue Service will not successfully assert a contrary position. Furthermore, no assurance can be given that future legislative, judicial or administrative changes, on either a prospective or retroactive basis, will not adversely affect the accuracy of the conclusions stated herein. Nevertheless, we undertake no responsibility to advise you of any new developments in the application or interpretation of the federal income tax laws.

(2) No opinion is expressed as to any transaction other than the Merger (whether or not undertaken in connection with the Merger) or as to any transaction whatsoever, including the Merger, if all the transactions described in the Agreement are not consummated in accordance with the terms of such Agreement and without waiver or breach of any material provision thereof or if all of the statements, representations, warranties and assumptions upon which we relied are not true and accurate at all relevant times. In the event any one of the statements, representations, warranties or assumptions upon which we have relied to issue this opinion is incorrect, our opinion might be adversely affected and may not be relied upon.

This opinion is rendered to you solely in connection with the filing of the Registration Statement. We hereby consent to the filing of this opinion as an exhibit to the Registration Statement. We also consent to the references to our firm name wherever appearing in the Registration Statement with respect to the discussion of the federal income tax consequences of the Merger, including any amendments to the Registration Statement. This opinion may not be relied upon for any other purpose, and may not be made available to any other person, without our prior written consent.

Very truly yours,

The Committee may adopt its own rules of procedure, and the action of a majority of the Committee, taken at a meeting or taken without a meeting by a writing signed by such majority, shall constitute action by the Committee. The Committee shall have the power and authority to administer, construe and interpret the Plan, to make rules for carrying it out and to make changes in such rules. Any such interpretations, rules, and administration shall be consistent with the basic purposes of the Plan.

(b) The Committee may delegate to the Chief Executive Officer and to other senior officers of the Corporation its duties under the Plan subject to such conditions and limitations as the Committee shall prescribe except that only the Committee may designate and make Grants to Participants who are subject to Section 16 of the Exchange Act or Section 162(m) of the Code.

(c) The Committee may employ attorneys, consultants, accountants, appraisers, brokers or other persons. The Committee, the Corporation, and the officers and directors of the Corporation shall be entitled to rely upon the advice, opinions or valuations of any such persons. No member of the Committee shall be personally liable for any action, determination or interpretation made in good faith with respect to the Plan or the Grants, and all members of the Committee shall be fully protected by the Corporation with respect to any such action, determination or interpretation.

(d) The Committee may construe and interpret the Plan and the Grants awarded thereunder and establish, amend and revoke rules and regulations for the administration of the Plan, including, but not limited to, correcting any defect or supplying any omission, or reconciling any inconsistency in the Plan or in any Grant Agreement, in the manner and to the extent it shall deem necessary or advisable to make the Plan fully effective.

(e) The Committee may determine the duration and purposes for leaves of absence which may be granted to a Participant on an individual basis without constituting a termination of employment or service for purposes of the Plan.

(g) All decisions and determinations by the Committee in the exercise of the powers conferred upon it under the Plan shall be final, binding and conclusive upon the Company, the Subsidiaries, Participants and all other persons having any interest therein.

4. ELIGIBILITY

The Committee may from time to time make Grants under the Plan to such Employees, or other persons having a relationship with the Corporation or any of its Subsidiaries, and in such form and having such terms, conditions and limitations as the Committee may determine. No Grants may be made under this Plan to non-employee directors of the Corporation or any of its Subsidiaries. Grants may be granted singly, in combination or in tandem. The terms, conditions and limitations of each Grant under the Plan shall be set forth in a Grant Agreement, in a form approved by the Committee, consistent, however, with the terms of the Plan; provided, however, such Grant Agreement shall contain provisions dealing with the treatment of Grants in the event of the termination, death or disability of a Participant, and may also include provisions concerning the treatment of Grants in the event of a change of control of the Corporation.

5. GRANTS

From time to time, the Committee will determine the forms and amounts of Grants to Participants. Grants shall be subject to such terms and conditions, including without limitation, vesting and exercisability periods or restrictions, and the effect on a Grant of a termination or change in employment status of a Participant (including a termination or change by reason of a sale of a subsidiary or division of the Corporation), as the Committee may in its discretion determine. Such Grants may take the following forms in the Committee's sole discretion:

(a) INCENTIVE STOCK OPTIONS - These are stock options within the meaning of Section 422 of the Code, to purchase Common Stock. In addition to other restrictions contained in the Plan, an option granted under this Paragraph 5(a),
(i) may not be exercised more than 10 years after the date it is granted, (ii) may not have an option price less than the Fair Market Value of Common Stock on the date the option is granted, (iii) must otherwise comply with Code Section 422, and (iv) must be designated as an "Incentive Stock Option" by the Committee. The maximum aggregate Fair Market Value of Common Stock (determined at the time of each Grant) with respect to which any Participant may first exercise Incentive Stock Options under this Plan and any Incentive Stock Options granted to the Participant for such year under any plans of the Corporation or any Subsidiary in any calendar year is $100,000. Payment of the option price shall be made in cash or in shares of Common Stock, or a combination thereof, in accordance with the terms of the Plan, the Grant Agreement, and of any applicable guidelines of the Committee in effect at the time.

4

(b) OTHER STOCK OPTIONS - These are options to purchase Common Stock which are not designated by the Committee as "Incentive Stock Options". At the time of the Grant the Committee shall determine, and shall have contained in the Grant Agreement or other Plan rules, the option exercise period, the option price, and such other conditions or restrictions on the grant or exercise of the option as the Committee deems appropriate, which may include the requirement that the grant of options is predicated on the acquisition by the optionholder of Purchase Stock under Paragraph 5(e) by the Optionee. In addition to other restrictions contained in the Plan, an option granted under this Paragraph 5(b),
(i) may not be exercised more than 10 years after the date it is granted and
(ii) may not have an option exercise price less than 30% of the Fair Market Value of Common Stock on the date it is granted.

(c) STOCK APPRECIATION RIGHTS - These are rights that on exercise entitle the holder to receive the excess of (i) the Fair Market Value of a share of Common Stock on the date of exercise over (ii) the Fair Market Value on the date of Grant (the "base value") multiplied by (iii) the number of rights exercised as determined by the Committee. Stock Appreciation Rights granted under the Plan may, but need not be, granted in conjunction with an Option under Paragraph 5(a) or 5(b). The Committee, in the Grant Agreement or by other Plan rules, may impose such conditions or restrictions on the exercise of Stock Appreciation Rights as it deems appropriate, and may terminate, amend, or suspend such Stock Appreciation Rights at any time. No Stock Appreciation Right granted under this Plan may be exercised more than 10 years after the date it is granted.

(d) RESTRICTED STOCK - Restricted Stock is Common Stock delivered to a Participant with restrictions or conditions on the Participant's right to transfer or sell such stock; provided that the price of any share of Restricted Stock delivered for consideration other than services and not as bonus stock may not be less than 30% of the Fair Market Value of a share of Common Stock on the date such Restricted Stock is granted or the price of such Restricted Stock may be the par value of a share of Common Stock. The number of shares of Restricted Stock and the restrictions on such shares shall be as the Committee determines, in the Grant Agreement or by other Plan rules, and the certificate for the Restricted Stock shall bear evidence of the restrictions or conditions.

(e) PURCHASE STOCK - Purchase Stock are shares of Common Stock offered to a Participant at such price as determined by the Committee; provided, however, that the price per share of such Purchase Stock may not be less than 30% of the Fair Market Value of the Common Stock on the date such shares of Purchase Stock are offered.

(f) DIVIDEND EQUIVALENT RIGHTS - These are rights to receive cash payments from the Corporation at the same time and in the same amount as any cash dividends paid on an equal number of shares of Common Stock to shareholders of record during the period such rights are effective. The Committee, in the Grant Agreement or by other Plan rules, may impose such restrictions and conditions on the Dividend Equivalent Rights, including the date such rights will terminate, as it deems appropriate, and may terminate, amend, or suspend such Dividend Equivalent Rights at any time.

(g) PERFORMANCE UNITS - These are rights to receive at a specified future date, payment in cash of an amount equal to all or a portion of the value of a unit granted by the Committee. At

5

the time of the Grant, in the Grant Agreement or by other Plan rules, the Committee must determine the base value of the unit, the performance factors applicable to the determination of the ultimate payment value of the unit and the period over which Corporation performance will be measured. These factors must include a minimum performance standard for the Corporation below which no payment will be made and a maximum performance level above which no increased payment will be made. The term over which Corporation performance will be measured shall be not less than six months.

(h) PERFORMANCE SHARES - These are rights to receive at a specified future date, payment in cash or Common Stock, as determined by the Committee, of an amount equal to all or a portion of the (i) average of the Fair Market Value of a share of Common Stock on each trading day during the last forty-five (45) days of such period, multiplied by (ii) a specified number of shares of Common Stock. At the time of the Grant, the Committee, in the Grant Agreement or by Plan rules, will determine the factors which will govern the portion of the rights so payable and the period over which performance will be measured. The factors will be based on Corporation performance and must include a minimum performance standard for the Corporation below which no payment will be made and a maximum performance level above which no increased payment will be made. The term over which Corporation performance will be measured shall be not less than six months. Performance Shares will be granted for no consideration other than services.

(i) OTHER STOCK-BASED GRANTS - The Committee may make other Grants under the Plan pursuant to which shares of Common Stock (which may, but need not, be shares of Restricted Stock pursuant to Paragraph 5(d)), are or may in the future be acquired, or Grants denominated in stock units, including Grants valued using measures other than market value. Other Stock-Based Grants may be granted with or without consideration; provided, however, that the price of any such Grant made for consideration other than services that provides for the acquisition of shares of Common Stock or other equity securities of the Corporation may not be less than 30% of the Fair Market Value of a share of the Common Stock or such other equity securities on the date of grant of such Grant. Such Other Stock-Based Grants may be made alone, in addition to or in tandem with any Grant of any type made under the Plan and must be consistent with the purposes of the Plan.

(j) MANNER OF EXERCISE AND PAYMENT OF STOCK OPTIONS - A Stock Option, or portion thereof, shall be exercised for whole shares of Common Stock by delivery of a written notice of exercise to the Corporation and payment of the full exercise price of the shares being purchased. A Participant may exercise a Stock Option with respect to less than the full number of shares for which the Stock Option may then be exercised. The price of Common Stock purchased pursuant to an Option, or portion thereof, may be paid:

(1) in United States dollars in cash or by check, bank draft or money order payable to the order of the Corporation,

(2) through the delivery of shares of Common Stock (which the Participant has held for at least six months prior to delivery of such shares or where the Participant has purchased on the open market and for which the Participant holds title free and clear of all liens

6

and encumbrances) with an aggregate Fair Market Value on the date of exercise equal to the exercise price,

(3) by delivery of an irrevocable notice of exercise to a financial institution acceptable to the Corporation to deliver promptly to the Corporation the portion of sale or loan proceeds sufficient to pay the exercise price,

(4) through the written election of the Participant to have shares of Common Stock withheld by the Corporation from the shares otherwise to be received, with such withheld shares having an aggregate Fair Market Value on the date of exercise equal to the exercise price or Federal, state and local tax withholding obligations in connection with such exercise or

(5) by any combination of the above methods of payment.

The Committee shall have sole discretion to disapprove of an election for delivering or withholding Common Stock upon exercise of a Stock Option in accordance with clauses (2)-(5) above and may impose such limitations and prohibitions on the use of Common Stock to exercise a Stock Option as it deems appropriate, including, without limitation, any limitation or prohibition designed to avoid certain accounting consequences which may result from the use of Common Stock as payment upon exercise of a Stock Option or tax withholding obligation. If the method of payment in clause (3) is elected, the Stock Option will be deemed to be exercised simultaneously with the sale of the shares by the financial institution. If the shares to be acquired on such exercise cannot be sold for a price equal to or greater than the full Exercise Price, then there will be no exercise of the Stock Option.

(k) NONTRANSFERABILITY OF DERIVATIVE SECURITIES: No Stock Option or Stock-Based Grant which constitutes a Derivative Security shall be transferable otherwise than by will, the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Corporation or be subject to attachment, execution or other similar process. In the event of any attempt by the Participant to alienate, assign, pledge, hypothecate or otherwise dispose of a Stock Option or any such Stock-Based Grant or of any right hereunder, except as provided for herein, or in the event of any levy or any attachment, execution or similar process upon the rights or interest hereby conferred, the Corporation may terminate the Stock Option or such Stock-Based Grant by notice to the Participant and the Stock Option or such Stock-Based Grant shall thereupon become null and void. Notwithstanding the foregoing, the Committee may provide, either at the time of grant or otherwise, that a Stock Option or Stock-Based Grant constituting a Derivative Security is transferrable to the extent that such transferability is permissible under BOTH Rule 16b-3 under the Exchange Act and the form of Registration Statement under which securities issued under the Plan are registered under the Securities Act of 1933.

6. LIMITATIONS AND CONDITIONS

(a) Subject to Paragraph 4, the number of shares available for Grants under this Plan shall be 6,437,750 shares of Common Stock reduced by the sum of the aggregate amount of shares issued upon a Grant or become subject to an outstanding Grant. The number of shares subject to Grants under this Plan to any one Participant during any calendar year shall not be more than 4,816,400 shares of Common Stock. To the extent that shares related to outstanding

7

Grants are not issued by reason of Grants being forfeited, terminated, cancelled, expire unexercised or delivered or withheld to pay the exercise price or satisfy withholding obligations, then such shares shall again immediately become available for Grants.

(b) No Grants shall be made under the Plan beyond ten years after the effective date of the amendment and restatement of the Plan, but the terms of Grants made on or before the expiration thereof may extend beyond such expiration. At the time a Grant is made or amended or the terms or conditions of a Grant are changed, the Committee may provide for limitations or conditions on such Grant.

(c) Nothing contained herein shall affect the right of the Corporation to terminate any Participant's employment at any time or for any reason.

(d) Deferrals of Grant payouts may be provided for, at the sole discretion of the Committee, in the Grant Agreements.

(e) Except as otherwise prescribed by the Committee, the amounts of the Grants for any employee of a Subsidiary, along with interest, dividend, and other expenses accrued on deferred Grants shall be charged to the Participant's employer during the period for which the Grant is made. If the Participant is employed by more than one Subsidiary or by both the Corporation and a Subsidiary during the period for which the Grant is made, the Participant's Grant and related expenses will be allocated between the companies employing the Participant in a manner prescribed by the Committee.

(f) Participants shall not be, and shall not have any of the rights or privileges of, stockholders of the Corporation in respect of any Shares subject to any Grant unless and until certificates representing any such Shares have been issued by the Corporation to such Participants.

(g) No election as to benefits or exercise of any Grant may be made during a Participant's lifetime by anyone other than the Participant except by a legal representative appointed for or by the Participant.

(h) Any Grant shall not be deemed compensation for purposes of computing benefits or contributions under any retirement plan of the Corporation or its Subsidiaries and shall not affect any benefits under any other benefit plan of any kind or subsequently in effect under which the availability or amount of benefits is related to level of compensation. This Plan is not a "Retirement Plan" or "Welfare Plan" under the Employee Retirement Income Security Act of 1974, as amended.

(i) Unless the Committee determines otherwise, no benefit or promise under the Plan shall be secured by any specific assets of the Corporation or any of its Subsidiaries, nor shall any assets of the Corporation or any of its Subsidiaries be designated as attributable or allocated to the satisfaction of the Corporation's obligations under the Plan.

7. TRANSFERS AND LEAVES OF ABSENCE

8

For purposes of the Plan a transfer of a Participant's employment without an intervening period of separation among the Corporation and any Subsidiary shall not be deemed a termination of employment.

8. ADJUSTMENTS

In the event of a stock split, spin-off, stock dividend, stock combination or reclassification, recapitalization or merger, change of control, or similar event, the Committee may adjust appropriately the number or kind of Shares subject to the Plan and available for or covered by Grants and Share prices related to outstanding Grants and make such other revisions to outstanding Grants as it deems are equitably required.

9. CHANGE IN CONTROL

Except as otherwise provided in a Grant Agreement, in the event of a Change in Control, the Committee in its sole discretion and without liability to any person may take such actions, if any, as it deems necessary or desirable with respect to any award granted under the Plan (including, without limitation,
(i) the acceleration of vesting or exercisability of an award, (ii) the expiration of an award following a Change in Control, (iii) the payment of a cash amount in exchange for the cancellation of an award which, in the case of Stock Options may equal the excess, if any, of the fair market value per share of Common Stock over the option price, and/or (iv) the requiring of the issuance of substitute awards that will substantially preserve the value, rights and benefits of any affected awards previously granted hereunder) effective as of the date of the consummation of the Change in Control.

10. AMENDMENT AND TERMINATION

The Committee shall have the authority to make such amendments to any terms and conditions applicable to outstanding Grants as are consistent with this Plan provided that, except for adjustments under Paragraph 8 or 9 hereof, no such action shall modify such Grant in a manner adverse to the Participant without the Participant's consent except as such modification is provided for or contemplated in the terms of the Grant. The Committee's authority hereunder shall include, without limitation, amendments to accelerate or waive vesting periods and to extend the exercisability (including to extend or provide for post-termination exercisability) of Stock Options or Stock-Based Grants, provided that such exercisability shall not extend past 10 years from the date of grant of such Stock Options, Stock-Based Grants or Other Stock-Based Grants.

The Board of Directors may amend, suspend or terminate the Plan except that no such action, other than an action under Paragraph 8 or 9 hereof, may be taken which would, without shareholder approval, increase the aggregate number of Shares available for Grants under the Plan, decrease the price of outstanding Options or Stock Appreciation Rights, change the requirements relating to the Committee or extend the term of the Plan.

11. FOREIGN OPTIONS AND RIGHTS

9

The Committee may make Grants to Employees who are subject to the laws of nations other than the United States, which Grants may have terms and conditions that differ from the terms thereof as provided elsewhere in the Plan for the purpose of complying with foreign laws.

12. WITHHOLDING TAXES

WHEREAS, the Company has adopted the PRIMEDIA 2001 Stock Incentive Plan (the "Plan"), which Plan as it may be amended from time to time is incorporated herein by reference and made a part of this Agreement;

WHEREAS, the Compensation Committee of the Board of Directors has determined that it would be in the best interests of the Company and its stockholders to grant the restricted stock award provided for herein (the "Restricted Stock Award") to the Participant pursuant to the Plan and the terms set forth herein;

WHEREAS, the Company and the Participant have entered into an employment agreement dated October 29, 2000 (the "Employment Agreement"); and

WHEREAS, the Employment Agreement provides for the grant of restricted stock to the Participant;

NOW THEREFORE, in consideration of the mutual covenants hereinafter set forth, the parties hereto agree as follows:

1. GRANT OF THE RESTRICTED SHARES. Subject to the terms and conditions of the Plan, and the additional terms and conditions set forth in this Agreement, the Company hereby grants to the Participant a Restricted Stock Award consisting of [ ] shares of Common Stock (the "Restricted Shares"), in consideration of the Participant's payment of the par value of $.01 per share of Common Stock, for a total payment of $[ ].

Notwithstanding the foregoing, in the event the above vesting schedule results in the vesting of any fractional Shares, such fractional Shares shall not be deemed vested hereunder but shall vest and become nonforfeitable when such fractional Shares aggregate whole Shares.

(b) If the Participant's employment with the Company is terminated for any reason, the Restricted Shares shall, to the extent not then vested, be forfeited by the Participant without consideration; PROVIDED, HOWEVER, that if the Participant is terminated (i) by the Company without Cause (as defined in the Employment Agreement), (ii) by the Participant with Good Reason (as defined in the Employment Agreement) or (iii) due to the Participant's death or Disability (as defined in the Employment Agreement), all Restricted Shares, to the extent not then vested, shall become immediately vested and nonforfeitable; PROVIDED, FURTHER, that if the Participant resigns due to a Diminution (as defined in the Employment Agreement), fifty percent of the Restricted Shares that were not vested as of the date of termination shall become immediately vested and nonforfeitable.

(c) Notwithstanding any other provision of this Agreement to the contrary, in the event of a Change of Control, the Restricted Shares shall, to the extent not then vested and not previously forfeited, immediately become fully vested and nonforfeitable.

3. CERTIFICATES. Certificates evidencing the Restricted Shares shall be issued by the Company and shall be registered in the Participant's name on the stock transfer books of the Company promptly after the date hereof, but shall remain in the physical custody of the Company or its designee at all times prior to the vesting of such Restricted Shares pursuant to Section 2. The Participant hereby acknowledges and agrees that the Company shall retain custody of such certificate or certificates until the restrictions imposed by Section 2 on the Common Stock granted hereunder lapse. As a condition to the receipt of this Restricted Stock Award, the Participant shall deliver to the Company a stock power or powers, duly endorsed in blank, relating to the Restricted Shares.

The Participant is hereby advised to seek his own tax counsel regarding the taxation of the grant of Restricted Shares made hereunder.
