From Facebook Investor to Vocal Critic: Roger McNamee on Getting 'Zucked'

Venture capitalist Roger McNamee has not always been an outspoken critic of Facebook. He was an early investor in the company and a mentor to founder Mark Zuckerberg. In his new book, “Zucked: Waking Up to the Facebook Catastrophe,” McNamee tells the story of his growing disillusionment with the company. In particular, he looks at how Facebook’s advertising tools, the key to their business model, have been easily manipulated by political interests and private companies. McNamee joins us in the studio to talk about Facebook, his relationship with Zuckerberg and the rise of companies that sell users’ data for profit.
