Exhibit 99.1    Press Release issued by the Registrant, dated October 6, 2004.




                                                                Exhibit 99.1

                      VIACOM ANNOUNCES PRELIMINARY RESULTS
               OF SUCCESSFUL BLOCKBUSTER SPLIT-OFF EXCHANGE OFFER

                        Exchange Offer is Oversubscribed;
             Final Results to be Announced on or before October 13th

NEW YORK, October 6, 2004 - Viacom Inc. (NYSE: VIA and VIA.B) today announced
that, based on preliminary results, its exchange offer for the split-off of
Blockbuster Inc. (NYSE: BBI and BBI.B) was oversubscribed. The successful offer
to Viacom stockholders for the exchange, on a tax-free basis, of some or all of
their Viacom shares for shares of Blockbuster common stock held by Viacom
expired at 12:00 midnight, New York City time, on October 5, 2004.

Based on a preliminary count by the exchange agent, The Bank of New York,
294,926,641 shares of Viacom common stock, consisting of 4,648,793 shares of
Viacom class A common stock and 290,277,848 shares of Viacom class B common
stock, were tendered for exchange. Of these shares, 150,315,329 shares of Viacom
common stock, consisting of 1,287,577 shares of Viacom class A common stock and
149,027,752 shares of Viacom class B common stock, were tendered by notice of
guaranteed delivery. Viacom will accept for exchange 27,961,165 shares of Viacom
common stock in exchange for the 72 million shares of Blockbuster class A common
stock and 72 million shares of Blockbuster class B common stock Viacom owns.
Because the exchange offer is oversubscribed, Viacom will accept only a portion
of the number of shares of each class of Viacom common stock that were tendered,
on a pro-rata basis in proportion to the number of shares tendered. Based on the
preliminary results, and assuming all shares tendered by notice of guaranteed
delivery are delivered under the terms of the exchange offer, Viacom will accept
approximately 9.5% of the tendered shares of each class of Viacom common stock.
Viacom expects to announce the final results of the exchange offer, including
the final proration factor, on or before Wednesday, October 13, 2004.

Stockholders that have tendered less than 100 shares, or an odd-lot, will not be
subject to proration, except that stockholders that have tendered odd-lots as a
participant in a Viacom or Blockbuster employee benefit plan are not entitled to
this preference.

Viacom commenced the exchange offer on September 8, 2004 and offered to exchange
5.15 shares of Blockbuster stock, consisting of 2.575 shares of Blockbuster
Class A common stock and 2.575 shares of Blockbuster Class B common stock, for
each share of Viacom common stock validly tendered and not properly withdrawn,
up to an aggregate of 27,961,165 shares of Viacom class A or class B common
stock.

Shares of Blockbuster common stock will be credited to accounts of tendering
stockholders by the exchange agent promptly after the final results of the
exchange offer are announced. In addition, checks in lieu of fractional
Blockbuster shares and shares of Viacom class A and class B common stock
tendered but not accepted for exchange are expected to be delivered or mailed on
or before October 22, 2004.
