         Viacom Is Exploring The Division Of Its Business Into Separate
                            Publicly-Traded Companies

NEW YORK, N.Y., March 16, 2005 -- Sumner M. Redstone, Chairman and Chief
Executive Officer of Viacom Inc., (NYSE: VIA and VIAB) announced today that he
has been exploring with the Company's Board of Directors the possible division
of its businesses into separate publicly-traded companies. Mr. Redstone said
that Viacom's Board authorized the Company to explore the separation as a means
to achieve important corporate objectives and to better deliver value to
shareholders in a tax-efficient manner. The Company expects to announce further
details regarding the possible separation in the second quarter of 2005.

Mr. Redstone said, "Viacom has an outstanding stable of assets with leadership
positions and excellent future prospects and I have for several months been
considering various alternatives to maximize our business opportunities in a way
that would best serve our shareholders. It is clear that, despite our success in
operating our businesses for maximum return, Viacom's businesses have inherently
different growth characteristics and investment attributes that appeal to
different types of investors. Furthermore, it has also become clear that this
important distinction is likely to continue to limit Viacom's ability to receive
full value for its assets and its prospects in the investment community.

"We believe that a separation of our businesses into distinct and strong
operating entities would allow us to optimize our capital structure and create
unique investments that are more appealing to investors with different
objectives," Mr. Redstone added. "Separately, these new publicly-traded entities
could each pursue strategic paths that would maximize their long-term potential.
The separation could highlight high-growth businesses, such as our MTV Networks,
which would be operated by Tom Freston, and could give us added flexibility to
pursue internal growth and to enhance these operations through the creation of
an attractive high-multiple currency that could be used for accretive
acquisitions. Additionally, we believe the separation is likely to allow us to
deliver greater value to our shareholders through a company operated by Les
Moonves that would combine our leading CBS broadcast television businesses with
our growing outdoor business and our high free cash flow operations, such as
radio. This group of assets would also have the potential to participate in a
program of stock buybacks and increased dividends.

"The transaction would further the logical and orderly succession process that
we put in place and would allow Viacom and its shareholders to take full
advantage of the skills and experience of our deep management. The transaction
should also enable us to retain the best people for each business and would
provide incentives for the creation of shareholder value that are more closely
tied to the businesses they run."

and cable television, radio, outdoor advertising, and online. With programming
