What was the name of NBC’s late-night program hosted by Jimmy Fallon that premiered in 2009?

NBC’s late-night program hosted by Jimmy Fallon that premiered in 2009 was Late Night with Jimmy Fallon.

The series premiered on March 2, 2009, with Fallon taking over the time slot previously occupied by Late Night with Conan O’Brien. It used the established Late Night structure: an opening monologue, celebrity interviews, comedy sketches, and musical guests.

Fallon brought elements of his Saturday Night Live background to the program, including impressions, musical comedy, and games involving guests. The show also became known for segments that spread widely online, helping NBC’s late-night brand reach audiences beyond conventional television viewing.

Fallon hosted Late Night until February 2014. He then moved to The Tonight Show, while Seth Meyers succeeded him as host of Late Night. The two titles are related but distinct: Late Night follows The Tonight Show in NBC’s schedule.
