NEW YORK-- Sept. 5, 2006--Viacom Inc. (NYSE: VIA - News and VIA.B - News) announced today that its Board of Directors has appointed Philippe P. Dauman, 52, President and Chief Executive Officer. The Board also named Thomas E. Dooley, 49, to the newly created position of Senior Executive Vice President and Chief Administrative Officer. Mr. Dauman succeeds Tom Freston, 60, who has resigned his positions with the Company.

Messrs.

Mr. Dauman will report to Sumner M. Redstone, Viacom's Executive Chairman and Founder, and to the Board of Directors of Viacom. Mr. Dooley will report to Mr. Dauman.

Messrs. Dauman and Dooley have worked closely with Mr. Redstone and with each other for more than 20 years. Since 2000, they have been Co-Chairmen and Chief Executive Officers of DND Capital Partners, L.L.C., a private equity firm specializing in media and telecommunication investments. Mr. Dauman, who has been a Director of Viacom since 1987, served from 1994 to 2000 as a member of Viacom's Executive Committee and as Executive Vice President in charge of strategic transactions, legal and government affairs, human resources and administration, with supervisory responsibility for Paramount Entertainment, Showtime Networks and Simon & Schuster. From 1993 to 1998, he also was General Counsel of Viacom.

Mr. Dooley held various corporate positions at Viacom from 1980 to 2000, including member of the Executive Committee and Executive Vice President, Finance, Corporate Development and Communications. He served as a member of the Viacom Board from 1996 to 2000 and rejoined the Board in 2006.

Sumner M. Redstone stated: "Viacom has tremendous potential to grow aggressively, both domestically and internationally. We have extremely strong and unique entertainment brands that resonate with audiences through all distribution platforms and a significant presence in worldwide motion picture production and distribution through our Paramount studio. I have worked closely with Philippe Dauman for many years, and I have a comfort level with him and high regard for his leadership abilities, strong financial and operational skills, and superb judgment. The entire Viacom Board and I are confident he has the strategic and creative vision to take the Company forward and the drive and energy to execute relentlessly on our strategy.

"I am also very pleased that Tom Dooley, who has worked very closely with Philippe and me over the years, has agreed to join us and bring his broad experience and considerable skills to bear in our efforts to accelerate Viacom's profitable growth in a rapidly evolving media environment. I could not be more pleased to be teaming up again with Philippe and Tom, who are two of the most extraordinary executives I have ever known and with whom I shared the most productive and successful period in Viacom's history."

Mr. Redstone continued, "I have great respect for Tom Freston and want to personally thank him for his tremendous contributions to Viacom over the past 20 years. Tom successfully built MTV Networks into an unmatched force in the entertainment industry and assembled a best-in-class operational team to build on that foundation. Tom has been a friend and a colleague for many years and we wish him well as he moves on to the next stage of his career."

Philippe Dauman stated: "I have been deeply involved with Viacom for most of my professional life and, like Sumner, I have a great passion for this company. Viacom, its exceptional people and its great brands have an intimate connection with the audience that is defining the digital revolution, which gives the Company enormous advantages and further potential. I intend to provide leadership, energy, and a focus on both creative and operational excellence as we work to execute on our strategy to drive Viacom's transformation into the digital media company of the future. I am also delighted that Tom Dooley, whom I have worked with for so long, has agreed to partner with me. He has strong financial, business, and people skills, and an association with Viacom that spans more than 25 years. I see this as the next chapter in a long-running and successful partnership at Viacom."

Tom Freston stated: "I've spent over 26 years at Viacom, 18 of them with Sumner. With my exceptional colleagues, we built a worldwide powerhouse of brands and businesses, literally from scratch. I leave many good friends knowing that they have an unmatched track record, a great plan going forward and incredible abilities to execute on it in this digital age. I have worked closely with Philippe Dauman and Tom Dooley over the years and have the highest respect for their abilities. I have every confidence that Viacom is well positioned to prosper under Philippe's leadership. I will do all I can to insure a smooth transition. I particularly want to thank my colleagues from all over the company who have been inspiring to work with and have been so instrumental in the great success we've had."
