I don't think any TV station would have him on any of their shows that had comedians on. He's way more offensive than anyone you see on TV. His 'jokes' are way too brutal to be accepted by any channel. He wouldn't stand a chance in getting a slot with the BBC.
He doesn't need television. He's a millionaire. His tours are usually a sell out, his DVD's sell well. He's not for me, but like it or not there's an audience for him.
