The Viacom and CBS Corp executive chairman made the donation via his Sumner M. Redstone Charitable Foundation as the museum celebrates its 25th anniversary. The Museum of the Moving Image in New York will rename its main theater the Sumner M. Redstone Theater beginning in May 2013. Redstone has been busy on the charity front this year, giving $10M to USC in January and last month the university christened a building in its Cinematic Arts complex the Sumner M. Redstone Production Building.
