TBS, as noted above, is not a great station. It was a local station in Atlanta until recently and besides braves baseball and Seinfeld reruns there just wasn't much going on.
But here is one exciting aspect. TBS is closely connected to Cartoon Network and thus Adult Swim. In fact, I think Adult Swim is in the old TBS building here in Atlanta. I'd love to see Conan dip into that think tank. They will all be in the same family.
Where's COCO gonna do his show? LA or NY?
