From The TV IV

Late Night is a long-running late night talk show franchise that follows The Tonight Show on NBC. The brand has been applied to three shows since it was established in 1982, which most notably launched the careers of David Letterman and Conan O'Brien in late night television. In 2009, O'Brien will leave his Late Night show for The Tonight Show and his place will be filled by Saturday Night Live alumni Jimmy Fallon.
