                                                                    EXHIBIT 7(a)

                 ACTV SIGNS LETTER AGREEMENT WITH LIBERTY MEDIA

         NEW YORK, May 8 /PRNewswire-FirstCall/ -- ACTV, Inc. (Nasdaq: IATV)
reported today that it has signed a letter agreement with Liberty Media
Corporation (NYSE: L) regarding a possible acquisition of all outstanding shares
of ACTV common stock.

         Under the terms of the letter agreement, Liberty, which currently owns
approximately 16% of ACTV's outstanding shares, would purchase all remaining
shares at a price of $2.00 per share. Such purchase price would be payable in
either cash, shares of Liberty Series A common stock, or the publicly traded
common stock of a Liberty subsidiary or affiliate. ACTV has entered into a
65-day exclusive negotiating period with Liberty with respect to the possible
transaction, during which Liberty will conduct due diligence and negotiate
definitive terms with ACTV. Should the exclusive period end without either a
signed definitive agreement between the parties, or a decision by either party
not to proceed with the possible transaction, Liberty may elect, for a period of
one day following the end of the exclusive period, to acquire the remaining
outstanding shares of ACTV at a price of $2.00 per share.

         Neither Liberty nor ACTV can provide any assurances that a definitive
agreement will be reached, or that a transaction ultimately will be consummated.
Any potential transaction calling for the acquisition of all outstanding shares
of ACTV common stock would require board approval of Liberty Media and ACTV as
well as ACTV shareholder approval.

         ACTV is being advised in this matter by Friedman, Billings, Ramsey &
Co., Inc.
