http://www.nma.tv Radio host Howard Stern announced through the Howard Stern Show show's Twitter account Thursday that he will be a judge on the NBC competition show America's Got Talent. Stern will join co-critics Howie Mandel and Sharon Osbourne when he takes over for Piers Morgan, who is leaving to concentrate on his CNN show, Piers Morgan Tonight. Stern will begin taping episodes in February, but they won't be shot in Los Angeles, where America's Got Talent has been produced for all of its six seasons. Instead, production will move to New York so that Stern can continue his Sirius XM Radio program. He is one year into a new five-year deal with the satellite radio carrier. Analysts estimate Stern's Sirius deal is worth $400 million. NBC representative Paul Telegdy praised Stern in a statement about the deal, saying the broadcaster's "larger-than-life personality will bring a thrilling new dynamic to America's Got Talent starting this summer." Joining an NBC show will be a strange homecoming of sorts for Stern. His 1985 firing from NBC's now-defunct New York City radio station was the stuff of legend, brought to life on the big screen in the 1997 film adaptation of Stern's semi-autobiographical book, Private Parts. Stern spent the better part of his terrestrial radio career at odds with the FCC, living up to his reputation as a crude "shock jock." The reigns of censorship loosened when Stern signed with subscriber-based Sirius, but he will once again find himself under scrutiny now that he is on a network television show. Stern seems serious about his role as a judge on America's Got Talent, telling his radio audience, "I take judging very seriously ... in order to up my credibility, I will wear a suit."
