30 Rock is an American satirical sitcom television series created by Tina Fey that originally aired on NBC from October 11, 2006, to January 31, 2013. The series, based on Fey's experiences as head writer for Saturday Night Live, takes place behind the scenes of a fictional live sketch comedy show depicted as airing on NBC. The series's name refers to 30 Rockefeller Plaza in New York City, where the NBC Studios are located and where Saturday Night Live is written, produced, and performed. The series was produced by Lorne Michaels's Broadway Video and Fey's Little Stranger, in association with NBCUniversal.

Saturday Night Live (SNL) is an American late-night live sketch comedy variety show created by Lorne Michaels and developed by Michaels and Dick Ebersol that airs on NBC and streams on Peacock. Michaels currently serves as the program's showrunner. The show's premiere was hosted by George Carlin on NBC on October 11, 1975, under the original title NBC's Saturday Night. The show's comedy sketches, which often parody contemporary American culture and politics, are performed by a large and varying cast of repertory and newer cast members. Each episode is hosted by a celebrity guest, who usually delivers the opening monologue and performs in sketches with the cast, with featured performances by a musical guest. An episode normally begins with a cold open sketch that was usually based on political events and ends with someone breaking character and proclaiming, "Live from New York, it's Saturday Night!", properly beginning the show.
