A lot of people have claimed “I’m With Coco,” and if that’s true than TBS has struck gold: Conan O’Brien (who just launched his 30-city tour last night) will be taking his late-night show to TBS, starting at 11 on weeknights and leading into “Lopez Tonight,” which will shift to midnight. Jay Leno and David Letterman will continue to come on at 11:30 on NBC and CBS — setting up a competition for viewership of sorts between all three shows — and will likely continue to stomp Conan O’Brien in ratings, as well as be horrendously unfunny. But that’s how America likes it.
