What show will claim the reality crown?

Is the appetite for reality television shows endless? Simon Cowell appears to think so. His newest show, "The X Factor," looms large over the reality field this fall, and, in typical Cowell style, he has bragged that "The X Factor" will claim the No. 1 crown from FOX's "American Idol." In his favor: sweet, loopy Paula Abdul; himself; and $5 million in prize money. But unlike when "Idol" first aired, there's a whole lotta reality competition out there. Johnny-come-lately shows like "The Voice" have proved that with the right celebrity mix (Team Blake Shelton!), a new gimmick (swivel chairs!) and just enough talent to make the show watchable, it is possible to have a hit even when merely handing out a record deal. We examine the shows that have hit the reality-show sweet spot.
