American cultural icon and television personality, Oprah Winfrey is one of the wealthiest entertainers in the world.
The Oprah stamp of approval is perhaps the most commercially valuable endorsement in contemporary American society. She has backed Bernhard Schlink, Dr. Phil, Barack Obama, Rachel Ray, and–in an amusing contretemps–the ennervating fabulist James Frey. She publishes an extremely popular monthly magazine called O, for which she is the exclusive cover girl.
