DATE:    June 14, 2005

We have some very exciting and important news to share with you. Today, the
Viacom Board of Directors approved the creation of two separate publicly traded
companies from Viacom's businesses through a spin-off to Viacom shareholders.
Even for a company with a history of industry-leading milestones and significant
successes, this is a landmark announcement.

This decision was the result of careful and thorough deliberation by the Viacom
Board of Directors, who, working with me and with the Viacom management team,
considered a number of strategic options that we felt could maximize the future
growth of our businesses and unlock the value of our assets. Viacom's businesses
are vibrant and we believe that the creation of two separate companies will not
only enhance our strength, but also improve our strategic, operational and
financial flexibility.

In many ways, today's decision is a natural extension of the path we laid out in
creating Viacom. We are retaining the significant advantages we captured in the
Paramount and CBS mergers and, at the same time, recognizing the need to adapt
to a changing competitive environment. We are proud of what we have created here
at Viacom, and want to ensure we can efficiently capitalize on our skills and
our innovative ideas, as well as all the business opportunities that arise --
while recognizing the significant untapped business and investment potential of
our brands.

Details regarding the two new companies will be worked out over the coming
months, and we will share with you the decisions and progress we make along the
way. What we do know is that the new company created through the tax-free
spin-off will keep the Viacom Inc. name and will be led by Tom Freston. The new
Viacom will be comprised of MTV Networks (including MTV, VH1, Nickelodeon, Nick
at Nite, Comedy Central, CMT: Country Music Television, Spike TV and TV Land),
BET, Paramount Pictures, Paramount Home Entertainment and Famous Music. The
other company, to be called CBS Corporation, will be led by Leslie Moonves and
will combine the CBS and UPN broadcast networks, Viacom Television Stations
Group, Infinity Broadcasting, Viacom Outdoor, the CBS, Paramount and King World
television production operations, as well as Showtime, Simon & Schuster and
Paramount Parks.

Following the spin-off, which is expected to be completed in the first quarter
of 2006, I will continue to be Chairman and controlling shareholder of the new
Viacom and CBS, and both companies will be headquartered in New York.

While much of the talk in the coming weeks and months will be about businesses
and assets, we know that our employees are our greatest assets. And we are
committed to ensuring the restructuring proceeds in a thoughtful manner that
reflects the respect and appreciation we have for all employees. We expect to
announce the senior management teams of both companies shortly and thereafter
quickly determine the appropriate corporate staffs for each organization. This
will obviously bring a great deal of change over the next few months given that
we are creating two organizations from 



one. Any Viacom employees whose jobs are impacted will have access to job
opportunities within the new organizations, as well as a full range of
assistance. As always, please feel free to contact your HR representative with
any questions you might have as we move forward.

It's an exciting new day for us all. Together we have grown and prospered, and
as two separate companies we will create new opportunities for our brands and
talents to shine. I thank you for all your past contributions and look forward
to working with all of you as we start another great chapter in the Viacom
story.

                   VIACOM BOARD OF DIRECTORS APPROVES CREATION
               OF TWO PUBLICLY TRADED COMPANIES FOLLOWING SPIN-OFF

         Tax-Free Spin-Off to Maximize Long-Term Potential of Businesses
               and Highlight Value of Leading Entertainment Brands


NEW YORK, June 14, 2005 -- Sumner M. Redstone, Chairman and Chief Executive
Officer of Viacom Inc. (NYSE: VIA and VIA.B), announced today that the Company's
Board of Directors has unanimously approved the creation of two separate
publicly traded companies from the Company's leading entertainment brands
through a spin-off to Viacom stockholders.

The transaction will result in stockholders holding shares in both companies,
and is expected to be tax-free to shareholders. Following the spin-off, which is
expected to be completed in the first quarter of 2006, Sumner Redstone will
serve as Chairman and will be the controlling shareholder of the companies,
which will both be headquartered in New York.

Viacom also announced that the Board of Directors has named Shari Redstone to
the newly created position of Non-Executive Vice Chairman of the Board. Ms.
Redstone, President of National Amusements Inc., has been a member of the Viacom
Board since 1994. Additionally, in line with its ongoing corporate governance
initiatives, the Company announced that Frederic V. Salerno, a member of the
Viacom Board since 1994 and former Vice Chairman and Chief Financial Officer of
Verizon Communications Inc., has been appointed to the newly created position of
Lead Independent Director. The appointment reflects Mr. Salerno's role as Chair
of the Board's Nominating and Governance Committee.

Mr. Redstone said, "Today we celebrate our past successes by stepping forward to
embrace the future. This transaction is the logical extension of the strategic
vision that created Viacom and recognizes the inherent diversity of our assets
as well as the changing business environment. We believe that this transaction
will enable Viacom 




shareholders to fully benefit from the important gains we realized in building
this Company by fully unlocking our significant untapped potential and creating
new opportunities to build on our leadership positions, maximize earnings growth
and fully exploit our considerable strengths."

"I want to commend the Viacom Board of Directors and the Viacom management team
for the careful and thorough strategic analysis that led to this important
decision," Mr. Redstone added. "The decision to create two new companies was the
result of intense study by the Board, which worked closely with the Company's
management and carefully analyzed all strategic options before reaching its
conclusion. The Board believes the transaction will result in two strong,
focused and nimble companies, and will better enable management to directly
impact and maximize the strengths of their respective businesses. Additionally,
the Board believes that the transaction will provide current and potential
stockholders with attractive investment options that are more closely aligned
with their various investment objectives."

Mr. Redstone added that the Board has formed a Special Committee, which he will
chair, that will assist and monitor the process of creating the two companies.
Also serving on the Committee will be Viacom Board members Shari Redstone,
Frederic Salerno and Philippe Dauman. Ms. Redstone will serve as Vice Chairman
of the Committee.

The new company created through the tax-free spin-off will retain the Viacom
Inc. name and will be led by Mr. Freston. The new Viacom will be comprised of
MTV Networks (including MTV, VH1, Nickelodeon, Nick at Nite, Comedy Central,
CMT: Country Music Television, Spike TV, TV Land and many other networks around
the world), BET, Paramount Pictures, Paramount Home Entertainment and Famous
Music. The other company, to be called CBS Corporation, will be led by Mr.
Moonves and will combine the CBS and UPN broadcast networks, Viacom Television
Stations Group, Infinity Broadcasting, Viacom Outdoor, the CBS, Paramount and
King World television production operations, as well as Showtime, Simon &
Schuster and Paramount Parks. Additional announcements regarding specific
details on the two new companies, including financial structures, management
teams and a more detailed timetable for the process, will be made over the next
several weeks.




"The new Viacom and CBS will have highly complementary business portfolios,
leadership positions in their industries and superior management teams that have
direct incentives to create greater shareholder value. In addition, each company
will have distinct capital structures designed to generate higher returns. Under
the leadership of Tom Freston and Leslie Moonves, shareholders of each company
will benefit from more focused long-term and individualized approaches that will
amplify the significant strengths of the respective businesses.

"The new Viacom will focus on organic expansion through the creation of
cutting-edge content, unrivaled brands, specialized and highly desirable
demographics and the continuing expansion of delivery platforms," Mr. Redstone
added. "We anticipate that this company's stock will attract a higher trading
multiple that can in turn be used for targeted acquisitions in promising areas.
With the increased importance of wireless, online and video gaming businesses,
the ability of the new Viacom to be opportunistic will be a distinct and
powerful advantage. Additionally, we believe that the new Viacom's significant
cash flow generation will provide the opportunity for significant share
repurchases."

"The new CBS will be a strong generator of free cash flow with industry-leading
positions across television and radio broadcasting, television production and
out-of-home advertising. With industry leading positions in content creation and
delivery, CBS will be extraordinarily well-positioned to maximize existing
opportunities and execute on new areas designed to create value. Importantly,
this company will also have the financial capability to return significant
capital to stockholders through dividend payments and stock repurchases."

Viacom is a leading global media company, with preeminent positions in broadcast
and cable television, radio, outdoor advertising, and online. With programming
that appeals to audiences in every demographic category across virtually all
media, the company is a leader in the creation, promotion, and distribution of
entertainment, news, sports, music, and comedy. Viacom's well-known brands
include CBS, MTV, Nickelodeon, Nick at Nite, VH1, BET, Paramount Pictures,
Infinity Broadcasting, Viacom Outdoor, UPN, TV Land, Comedy Central, CMT:
Country Music Television, King World, Spike TV, Showtime, Paramount Parks, and
Simon & Schuster. More information about Viacom and its businesses is available
