New York Magazine: When Les Moonves arrived at CBS 20 years ago this summer, the Eye network was pretty much in shambles. CBS’s owners decided to take a chance on Moonves, the well-respected head of Warner Bros. TV who’d led the studio to glory with “Friends” and “ER.” And it paid off, big-time. To mark the occasion of his 20th anniversary at CBS, Moonves has agreed to talk at length — and on the record — on a broad range of topics: the rapid evolution of the TV business, the rise of Netflix, the flux in late night, the FCC’s regulation of sex and language, and even the disappointing casting of this year’s edition of “Big Brother.”
