It's a profitable show for the network and relatively cheap to product. It's an easy way for the entertainment industry to shill their upcoming movies/TV shows/musical acts. Like sports and reality TV it's one of the few products that still lends itself to the network TV model in a world where DVDs and downloads are the place to go for quality fictional programs. You'll see NBC bring back Supertrain before they cancel the Tonight Show.
True, but there's really no reason to keep the old desk/couch/skyline picture format. A comedy/interview show could be completely different.
