NBC brass’ blessing was key in Piers Morgan landing his talk show host gig on CNN because he was under contract at the broadcast network as a judge on America’s Got Talent. Now Morgan is leaving NBC, which allowed him to fulfill his dream of succeeding Larry King, and the reality series that established him in the US to focus on his struggling primetime show on CNN. Morgan made the announcement on the CNN program, Piers Morgan Tonight. “I’m leaving America’s Got Talent,” he said. (video below) “I’ve been there since the show began 6 years ago and have loved every second of it but discovered that juggling is a bit more difficult than I thought.” NBC recently renewed the veteran talent competition for next summer.
