Early in the show, Howard welcomed 'AGT' producer Jason Raff to the studio--and asked him why Nick Cannon, 'AGT's' host, never promoted the show to his 17 million Twitter followers. Jason said there was little he could do: "We'd love to see him tweet some more. He does have a lot of followers. And Sharon, I don't think, is allowed to tweet by herself." Howard said he'd noticed as much: "Sometimes, when I'm sitting next to her, there's a woman tweeting by her side."
