Bloomberg: Shari Redstone, the daughter of 92-year-old Sumner Redstone and heir to his media empire, doesn’t hobnob in Hollywood. She’s never been to the Oscars or the Vanity Fair after-party. Yet she is poised to become the most powerful woman in entertainment, with a big say in what happens at CBS, the most-watched TV network, and Viacom, owner of Paramount Pictures. Her father, who is in poor health, made Shari, 61, and her 29-year-old son, Tyler Korff, the sole family representatives among seven trustees who will control $5.4 billion of stock in CBS and Viacom after he dies. “She very much believes the media landscape is evolving rapidly and she wants to be on top of the changes.”
