Interesting that The Tonight Show is listed, simply because that show is still on the air. The only thing that has changed over the years has been the host, the "series" hasn't really ended.
Actually there have been different names for shows under the Tonight Show franchise. There was Tonight!, Tonight Starring Steve Allen, Tonight! America After Dark, Tonight Starring Jack Paar, Jack Paar Tonight, The Tonight Show Starring Johnny Carson, The Tonight Show with Jay Leno, The Tonight Show With Conan O'Brien, and The Tonight Show Starring Jimmy Fallon. There was also a brief Johnny Carson Show on CBS. This would make a good quiz all on its own.
