Simon Cowell
Success rating Stateside: Americans really love him!
Simon Cowell is one of the most recognised figures on American TV today. Best known as the acerbic judge on talent show 'American Idol' with his signature phrase: "I don't mean to be rude, but..."
The show has been a ratings winner since it debuted in 2002 and the yanks can't get enough of him. Cowell has even signed on for another five years so it looks like his popularity isn't going to fade! The music mogul recons he's liked so much because he brings the US "probably the most realistic reality show" on American TV.
