I'm sure Colbert's CBS or whatever network's top choice, but I don't buy this rumor for a second (remember how Stewart was supposedly one of CBS's top choices to replace Dan Rather 
). But I hope you guys realize he'd just become another hyper-censored, humorless has-been TV hack who only makes safe jokes for old people like Leno, Fallon, Letterman, etc. CBS/ABC/NBC wouldn't offer even a sliver of the creative freedom Comedy Central offers. If Stewart or Colbert ever move to one of those networks, anyone who hates them should uncork the champaign, because whichever one of them went to CBS/ABC/NBC will have lost all influence and come to be seen as sell-outs by most of their audience in a year or two (at most). Stewart and Colbert have their niche on comedy central and would never be allowed to anything remotely like it on one of these creative wasteland networks. The best person who fits in the Leno/Letterman old-people niche is Craig Ferguson (who is decent enough at what he does), but no program on CBS/ABC/NBC will even be allowed to swear, let alone do anything even remotely edgy.
Fallon is younger skewing believe it or not. Also Ferguson is younger skewing as well despite his age. I think "older people" now don't matter to TV because advertisers now just want Gen Yers, and Letterman has been the older generation's last late night holdout. So any new late night host has to appeal to today's teens, 20-somethings, and 30-somethings.
