EXHIBIT INDEX ------------- Exhibit No. Description - -------- -------------- 99.1 Press release issued by Viacom Inc. on August 15, 2000


                  VIACOM OFFERS TO PURCHASE FULL OWNERSHIP OF
                       INFINITY BROADCASTING CORPORATION

New York, NY, August 15, 2000 - Viacom Inc. (NYSE: VIA, VIA.B) announced today
that it has offered to purchase the remaining shares of Infinity Broadcasting
Corporation (NYSE: INF) that it does not currently own for 0.564 of a share of
Viacom Class B Common Stock per share in a merger transaction.

Based on the Viacom Class B Common Stock closing price of $71.00 on August 14,
2000, the per share consideration equals $ 40.04 per share of Infinity Class A
Common Stock, representing a 13.6% premium over the Infinity Class A Common
Stock closing price of $35.25 per share on that date. Viacom currently holds
100% of Infinity's Class B Common Stock, which represents approximately
64.3% of the equity of Infinity and approximately 90.0% of the combined voting
power of Infinity's Class A and Class B Common Stock. Viacom does not
currently hold any of Infinity's Class A Common Stock.

Sumner M. Redstone, Chairman and Chief Executive Officer of Viacom, said, "With
both Viacom's and Infinity's core businesses performing at record levels, it is
the perfect time to bring them more closely together. Under Mel Karmazin's
leadership, Infinity has become the most successful radio and outdoor
advertising company in the world. Combining Infinity with Viacom will now create
a company that is financially even stronger and strategically even better
positioned to generate superior returns to shareholders."

Mel Karmazin, President and Chief Operating Officer of Viacom, said, "While the
Infinity IPO has been extraordinarily successful, we believe that Infinity
stockholders can realize even greater value through Viacom's offer. Not only
does the offer provide a significant premium on a tax-free basis, it also
enables Infinity shareholders to participate in the extraordinary opportunity
created by Infinity's full integration with Viacom's unique and powerful
businesses."

The merger proposal is subject to approval of Infinity's independent directors.
