Viacom chairman Sumner Redstone made his second decisive move intwo weeks as chief executive officer Tom Freston was ousted from the company yesterdayafter more than 25 years of service.

Philippe P Dauman, the 52-year-old former deputy chairman,replaces Freston as the new president and chief executive officer, and Thomas EDooley has been appointed to the newly created position of senior executive vicepresident and chief administrative officer.

Speaking in a conference call with reporters early on TuesdayRedstone stressed Freston's departure was not related to Tom Cruise. Two weeks agoRedstone went over the heads of Freston and Paramount chairman Brad Grey whenhe said the studio would not renew its contract with the star, and citedCruise's eccentric public behaviour and its effect on box office as the keyreasons.

Redstone wants to reclaim greater control over the company at atime when its stock price has been falling and communication with Wall Streethas deteriorated.

He is also clearly anxious that Viacom becomes more aggressive inthe online arena, and expressed annoyance during the conference call over losingout to Rupert Murdock's News Corp in the bidding for the online

Tom has been a friend and a colleague formany years and we wish him well as he moves on to the next stage of hiscareer."

"I've spent over 26 years at Viacom, 18 of them withSumner," Freston said. "With my exceptional colleagues, we built aworldwide powerhouse of brands and businesses, literally from scratch. I leavemany good friends knowing that they have an unmatched track record, a greatplan going forward and incredible abilities to execute on it in this digitalage. I have worked closely with Philippe Dauman and Tom Dooley over the yearsand have the highest respect for their abilities.

I will do all I can to insure a smooth transition.I particularly want to thank my colleagues from all over the company who havebeen inspiring to work with and have been so instrumental in the great successwe've had."
