What started as a small chain of movie theaters in the Boston suburbs is now a multimillion dollar media empire that includes CBS and Viacom. The man behind it, Sumner Redstone, got his start in 1967 after taking over the family business, which he turned into a media powerhouse over the next 40 years. But building this star-studded empire wasn’t without its costs, including a father-daughter estrangement that made its way into a court battle featuring two former live-in girlfriends accused of exploiting the aging media mogul for money.

Jim Braude was joined by Wall Street Journal reporter Keach Hagey, who chronicled the family soap opera in her new book, "The King of Content: Sumner Redstone's Battle for Viacom, CBS, and Everlasting Control of His Media Empire."
