For 50 years, television was a man’s business. It was an industry about dominance—winners took all. Big egos, brilliant gamesmanship, great wealth characterized the men who shaped the business. They all played the role: Bill Paley, David Sarnoff, Leonard Goldenson, Roone Arledge, Michael Eisner, Barry Diller, Tom Murphy, Dan Burke, Larry Tisch, Bob Wright, Dick Ebersol, Mel Karmazin, Sumner Redstone, Jeff Zucker, and Les Moonves—perhaps the last real TV guy standing. Showmen and sharks.
