Oprah Winfrey

Age: 58
Occupation: Media mogul

Winfrey's talk show ended last year, and the Oprah Winfrey Network's struggling ratings have made headlines. But Winfrey is no stranger to shaking things up, and she was quick to change management and shuffle the network's lineup after devoting her full attention to OWN last summer. The queen of all media still commands some of the most talked-about interviews on television, guaranteeing that wherever she goes, she'll have viewers clamoring to see who is sitting on her couch.
