America's Got Talent - What2Watch

Season 14 opened with a partial changing of the guard, as host Tyra Banks and longtime judges Heidi Klum and Mel B moved on to other projects, with the latter two replaced by actresses Gabrielle Union and Julianne Hough, and Terry Crews taking over as the show's permanent host. Veteran judges Simon Cowell and Howie Mandel continued as hordes of talented hopefuls either saw their dreams dashed or confirmed over the summer. Tonight's two-hour finale will see this season's winner crowned, preceded by many guest performances.
