> Howard Stern's 'America's Got Talent' hiring is desperate, says Parents Television Council
Stern was announced as an America's Got Talent judge late last year, joining Sharon Osbourne and Howie Mandel on the panel. He has promised to find "real talent... someone who can become a major superstar" on the show.
"I can assure you and the rest of America - what I'm looking at here is to be a very good judge," the shock jock told predecessor Piers Morgan in an interview last December.
Morgan stepped down from the America's Got Talent panel in November 2011, in order to spend more time working on his CNN show Piers Morgan Tonight ahead of the 2012 presidential elections.
America's Got Talent returns this summer on NBC.
