The Tonight Show is an American late-night talk show that has aired on NBC since 1954. Currently recorded in New York City, it is the longest currently running, regularly scheduled entertainment program in the United States and the third-longest-running show on NBC after Meet the Press and Today. It is the longest-running talk show in television history, surpassing Ireland's The Late Late Show by eight years. The show has undergone some minor title changes, having aired as Tonight for several of its early years, before settling on The Tonight Show in 1962. Aside from minor format changes, and a brief move to a more news-style format in 1957 before reverting back that same year, it has remained a talk show through-out its run.
The Tonight Show was hosted by Steve Allen (1954–57), Jack Paar (1957–62), Johnny Carson (1962–92), Jay Leno (1992–2009, 2010–14), Conan O'Brien (2009–10), and Jimmy Fallon (2014–present). Several guest hosts also appeared, particularly during the Paar and Carson eras. The current host is former Late Night host and Saturday Night Live cast member Jimmy Fallon.
