Variety: On the media front, Marissa Mayer has simply been out of her depth, insiders say. She came to Yahoo boasting Silicon Valley chops, but she has never had a real understanding of the media business. “She believes she can figure it out on her own,” said a former top Yahoo exec. “Her attitude is, ‘I watch TV shows, so I know TV shows.’” According to another media exec: “She got enamored with content — but she had zero expertise. And she hired people with even less experience.”
