From a Wall Street Journal review by Edward Kosner of the book by James B. Stewart and Rachel Abrams titled “Unscripted” The Epic Battle for a Media Empire and the Redstone Family Legacy”:

Sumner Redstone, who died in 2020 at the age of 97, was one of the killer whales thriving in the swirling currents of the modern media. A hulking old man with dyed red hair and a maimed right hand, he was a mega-billionaire with a ravenous appetite for power, riches—and sex. At his peak at the turn of the century, he controlled Viacom; Paramount Pictures; the National Amusements movie-theater chain; the CBS network, MTV, Comedy Central and Nickelodeon; and the Simon & Schuster publishing house. Then the end came in a crescendo of recrimination, litigation and family turmoil.
