In 13 years and 14 seasons, American Idol has seen just a handful of success stories that live up to its name. Contestants like Kelly Clarkson, Carrie Underwood, Jennifer Hudson, and Daughtry have become legitimate superstars, leaving an impact on popular culture that extends beyond the Fox show’s shadow. But most of the other contestants, even the winners and runners-up, seem to have fizzled as soon as the house lights of the Kodak Theatre went down. Fame is always fleeting, but it moves at a speedier pace for Idol winners.
