Philippe Dauman replaces Sumner Redstone as Viacom chairman
Viacom chief executive Philippe Dauman has adopted the role of chairman as he replaces Sumner Redstone who has stood down from the position.

The company announced on Thursday that Dauman will fill in for the 92 year-old who now moves up to the new position of chairman emeritus, reports Reuters.
The move came amid legal challenges made against the mental competency of Redstone.
Dauman is one of seven trustees and will hold almost 80 per cent of voting power at CBS and Viacom in the event of Redstone’s death.
Redstone earlier this week stepped down from the position of chairman at CBS.
Under Dauman’s control at Viacom will be brands including MTV, Nickelodeon, Comedy Central and Paramount Pictures film studios.
