The Washington Post Company, a Delaware corporation ("TWP"), hereby amends and supplements in its Statement on Schedule 13D (the "Original 13D") relating to the common stock, par value $0.10 per share (the "Common Stock"), of ACTV, Inc., a Delaware corporation (the "Issuer") with its principal executive offices at 1270 Avenue of the Americas, New York, NY 10020, as such Original 13D was filed with the Securities and Exchange Commission (the "Commission") by TWP on March 26, 1992 and subsequently amended. The Original 13D, as amended by amendment no. 1, amendment no. 2, amendment no. 3 and amendment no. 4 is hereinafter referred to as "Schedule 13D". All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in Schedule 13D. Item 4. Purpose of Transaction. The text of Item 4 is followed by the following: On March 4, 1999, TWP withdrew 1,600,000 shares of Common Stock from the Voting Trust described above. Between March 9, 1999 and March 26, 1999, TWP sold 705,000 shares of Common Stock at prices between $7.07374 and $7.6225 per share for a total of $5,211,545.57 (equal to $7.39226 per share) on NASDAQ through Salomon Smith Barney. From time to time, TWP may withdraw additional shares from the Voting Trust and sell such shares. Item 5. Interest in Securities of the Issuer. Item 5 of the Schedule 13D is hereby deleted in its entirety and substituted by the following: On March 4, 1999, TWP withdrew 1,600,000 shares of Common Stock from the Voting Trust described in Item 4 above. Between March 9, 1999 and March 26, 1999, TWP sold 705,000 shares of Common Stock at prices between $7.07374 and $7.6225 per share for a total of $5,211,545,57 (equal to $7.39226 per share) on NASDAQ through Salomon Smith Barney. TWP is deemed to beneficially own, in the aggregate, shares of Common Stock, or 4.926% of the outstanding Common Stock. Such percentage of shares is calculated on the basis that the 33,217,184 shares of Common Stock which the Issuer has disclosed were issued and outstanding on March 19, 1999, and continue to be the only shares of Common Stock outstanding.
