We're talking past each other because we very clearly have different definitions of what a Rushmore means. It's why it's not really worth debating this: we can't come to an agreement.
A show like Seinfeld is both popular and influential. It's an easy Rushmore for all involved. Arrested Development was wildly unpopular, but it's influence is shot through all contemporary good comedy. Big Bang Theory is derivative butt. (Scrubs is excellent, but not particularly influential, so though better than BBT isn't Rushmore material.)
The Wire is universally considered one of the best shows ever. I agree, and think it's the best show. It was not particularly popular, and even now the average tv viewer hasn't seen it. But for me the average tv viewer doesn't make the Rushmore.
That's the same thing with music. I just don't care enough about music to tell you who would take Bon Jovi's place. I can say with confidence, though, that Bon Jovi's mediocre music didn't bring anything new to the pop music scene, and has had no particularly interesting influence on what's come later. And that's not because their essentially a pop band--plenty of pop bands have done something interesting.
