While it may be called Britain's Got Talent, the UK reality show has become a worldwide phenomenon. The show has captured the imagination of the world, thanks in large part to stars like Susan Boyle and Paul Potts. Alas, Boyle didn't win the 2009 competition (that honor went to the dance-troupe Diversity). Still, the real winners are Simon Cowell and the team of Britain's Got Talent producers, who seem to have hit upon a formula for success that could last for years.
