Season seven of America 's Got Talent, a reality television series, premiered on May 14, 2012. Sharon Osbourne and Howie Mandel returned as judges. Judge Piers Morgan left the show after season six and was replaced by radio personality Howard Stern, as announced on his Sirius XM radio show on December 15, 2011. Because of Stern 's commitments to his radio program, the live (post-Las Vegas) episodes moved from Los Angeles to the New Jersey Performing Arts Center in Newark, New Jersey. The season ended on September 13, 2012, with Olate Dogs announced as the winners of the season. This was Sharon Osbourne 's final season.
