Well, he's been talking about it for the longest time on his show. I see the reaction to this being one of two camps: those, like me, who think he'll be a better judge than most think because he'll take it seriously and those who think he'll smut it up and try of get him off the air ASAP. If nothing else, 'America's Got Talent' will garner plenty of interest and headlines. I just don't know if it will get ratings: there are a lot of these talent reality shows (Idol, the Voice, X Factor) that I don't see a new host making that big a difference in the long run.
If nothing else, it gives us the hilarious subplot of Nick Cannon and his dumb ass, egoistical self having to deal with Stern calling him out on his BS on his own show now. I wonder how long he'll last once he gets the likes of Richard and Sal sicced on him.
If I recall correctly, it was a midseason replacement show...and the first season was short..13 episodes. I think the show could continue w/o Michael Scott...not sure how, but I think the cast is good enough to make it happen.
