I can't speak for anyone other than myself, but I don't watch anything other than Fallon these days, maybe a little of Fallon, because my local ABC airs it at 11:05 after a sickly 5 minute newscast. (Eastern Washington smaller market, sigh).
When it was Leno/Letterman I found myself going back and forth. Not so much today. I do like Conan, but I can catch him "on-demand".
He may well be replaced. I don't know how long his contract was for, but I'm not sure that's a consideration for CBS if they think they can improve the ratings with Corden.
Another alternative not mentioned: Conan. NBC never gave him a chance.
Colbert simply isn't very good outside of the persona he crafted on Comedy Central.
He may well be replaced. I don't know how long his contract was for, but I'm not sure that's a consideration for CBS if they think they can improve the ratings with Corden. Colbert would obviously be paid for the balance of his contract, but has nowhere to really go from there. Returning to Comedy Central would be a big step back and he'd be unlikely to land a show anywhere else.
Why wouldn't he return to Comedy Central? Keith Olbermann has returned to his sports roots a couple of times now after his outsized outrage got to be too much for his bosses at an entertainment division to handle, right? I always wondered why Craig Kilborn -- whom I found really funny at ESPN -- didn't return to ESPN or pop up at another sports operation after his venture into late night entertainment flopped.
The main problems with Colbert is that there is a bunch of things going on at the same time.
1. His type of comedy is too political and worked better with the "Colbert" character then the real Stephen Colbert and he is missing something but it might be the Character or "Cobert Report" exclusive bits that might be intellectual property of Comedy Central/Viacom.
2. It's rated TV-PG, which is not edgy enough for a late night show, while the rest of the shows are TV-14.
3. Oversaturation of the late night TV, one too many late nights shows on at th same time, Colbert is up against The Tonight Show on NBC, Jimmy Kimmel Live on ABC, The Nightly Show with Larry Wilmore on Comedy Central, and the second half of Conan O'Brien on TBS as well as other competition from west coast Sports events, reruns and syndication shows like Dish Nation and TMZ, ESPN SportsCenter, and of course, Adult Swim reruns of Family Guy.
4. The cord cutters who watch anything on-demand via internet, and it's possible Colbert is getting more views online then on the CBS at the 11:35 PM ET airing.
5. There are other political based late nights shows, some with Former Jon Stewart era Daily Show regulars hosting then. Last Week Tonight seems to be the best in this concept of late night show right now, cause John Oliver was truly the heir the Daily Show throne, but he left before Jon Stewart's retirement from the Daily Show and Trevor Noah became Stewart successor instead. Trevor has done ok, but he's no Jon Stewart or John Oliver.
And this the main problems with Colbert's run as the host of "The Late Show".
Also Colbert on CBS has to play within the playbook that Letterman has left off?
