Sumner Redstone

A cinema chain controlling media giants. Redstone used his family's cinema company, National Amusements, to buy voting control of Viacom in 1987 and later CBS, holding most of the votes through special shares with a small share of the equity. In his old age the structure turned succession into a public legal battle. His daughter Shari eventually sold National Amusements, and with it control of Paramount, to Skydance in 2025. He died in 2020.
