Well he was a fairly big star a few years back, he had a late evening tv show that was quite funny at the time, but since then I think it would be fair to say his star is in decline. The jokes started to get a bit repetitive and too mainstream, and I think he began to grate on people's nerves after a while.
He is still on tv, but is not really the man-of-the-moment he once was. Comedians like that tend to have a fairly limited shelf-life imo
