Late Night is an American late-night talk and variety show airing on NBC since 1982. Four men have hosted Late Night: David Letterman (1982–1993), Conan O'Brien (1993–2009), Jimmy Fallon (2009–2014), and Seth Meyers (2014–present). Each iteration of the show was built around its host, and maintained distinct identities aside from the title, timeslot, and network. The longest-serving host to date was O'Brien, who hosted Late Night with Conan O'Brien for almost 16 years, from September 1993 to February 2009.
