FRONTLINE continues its monthly magazine format with the lead story "Money and March Madness," an inside look at the multi-billion dollar business of the NCAA and its brand of amateur college sports. In this investigation, correspondent Lowell Bergman gains access to Sonny Vaccaro, a former marketing executive at Nike, Adidas and Reebok, who helped bring about the rapid commercialization of college basketball. Vaccaro's success made coaches, administrators and companies rich. But the players remain at the mercy of the NCAA, which, despite a new $10.8 billion contract for its basketball tournament, has continued to insist that the athletes don't get paid. Now, Vaccaro has left the business world and he is spearheading a class-action lawsuit that aims to ensure that players get a piece of the action. Also in this hour: a portrait of a man who's sometimes called China's Andy Warhol -- Ai Weiwei. He's a global art star who's now using his international renown, along with a video camera and a growing underground Twitter following, to push the boundaries of freedom in today's China. Later in the hour, as the fallout from WikiLeaks continues, an exclusive interview with Private Bradley Manning's father, who speaks out for the first time about his son's upbringing and troubled youth, Manning's time in the Army and why he still believes his son did not hand over the largest cache ever of classified documents to the whistle-blowing site.
