Who is Wade Robson?

And why does he have his own show on MTV here? It clearly is an American show, but I've never heard of it until now. For those of you who are with me on being clueless about this guy, the point of the show is for Wade to pick a dancer for one of his music videos. They start out with 4 dancers who all think they're really hot. They have to "freestyle" dance to random music, and learn a dance routine from Wade, and eventually 3 are eliminated. Can someone fill me in on this guy?
