                                                                EXHIBIT (A)(11)
 
           VIACOM ANNOUNCES FINAL EXCHANGE RATIO FOR CABLE SPLIT-OFF
 
  New York, New York, July 30, 1996--Viacom Inc. (AMEX: VIA and VIAB)
announced today that, upon completion of its previously announced cable split-
off exchange offer, it will accept for exchange 15,356,960 shares of its
common stock, including 5,417,211 shares of Class A Common Stock and 9,939,749
shares of Class B Common Stock, at a final exchange ratio of .4075 for each
share of Viacom common stock accepted after proration. The final proration
factor is approximately 65.52%. The exchange offer and related transactions
are expected to be completed on July 31.
 
  The exchange offer, which expired at midnight (EDT) on July 22, 1996,
provided Viacom shareholders with the opportunity to exchange shares of Viacom
Class A and Class B Common Stock for 6,257,961 common shares of Viacom's
split-off cable operation, to be renamed TCI Pacific Communications, Inc. (TCI
Pacific). The common shares of TCI Pacific will convert immediately after the
exchange into shares of preferred stock of TCI Pacific on a one-for-one basis.
 
  The Company said certificates for shares of preferred stock of TCI Pacific
and checks for cash payable in lieu of fractional shares will be mailed
promptly. All shares tendered and not exchanged will be returned to
stockholders. Estimated final results of the exchange offer, based on a
preliminary count by the exchange agent, were announced on July 23, 1996.
 
  The transaction allows Viacom to reduce its debt by $1.7 billion and reduce
the total number of outstanding common shares of Viacom by approximately 4.1%.
 
  Viacom Cable includes systems in five geographic regions, including the San
Francisco and Northern California area: Salem, Oregon; the Seattle, Washington
and greater Puget Sound area; Nashville, Tennessee and Dayton, Ohio. The
