Maybe he realized that the show was dead in the water and subs were falling off a cliff - and did AGT to attract new subs? Not that he gives two shits about the show in reality - but he wanted to cover his ass and protect the marbles that he had coming from it. AGT probably has a very family oriented audience that can digest his boring ass radio show. Some will even pay for it because they like AGT talk. Just saying the shoe fits.
