Piers Morgan announced on his CNN show tonight that he is leaving America's Got Talent after six years. Morgan noted that juggling between two shows was harder than it looked and that he was "going to focus on what will be a huge year at CNN."
So far 'Piers Morgan Tonight' hasn't exactly lit up the ratings for CNN since taking over Larry King's timeslot, routinely finishing third behind Fox News Channel's "Hannity' and MSNBC's 'Rachel Maddow Show.'
