Dethroned king of comedy.

The article discusses late night talk show host David Letterman and how he shaped late night television (TV) comedies. Topics include how the TV program "Late Night With David Letterman," which aired in 1982 on the National Broadcasting Company (NBC) network, deconstructed the late night show format, how he left NBC for CBS so that "Late Show With David Letterman" could compete with "The Tonight Show," and how his show influenced comedians such as Jon Stewart, Conan O'Brien, and Jimmy Kimmel.
