30 Rock is an American television comedy series that ran on NBC from October 11, 2006 to January 31, 2013 and was created by Tina Fey. The series, which is loosely based on Fey's experiences as head writer for Saturday Night Live, takes place behind the scenes of a fictional live sketch comedy series depicted as airing on NBC. The series' name refers to 30 Rockefeller Plaza in New York City, the address of the GE Building, in which the NBC Studios are located. This series is produced by Broadway Video and Little Stranger, Inc., in association with NBCUniversal.
30 Rock episodes are produced in a single camera setup (with the exception of the two live episodes that were taped in the multi-camera format), and are filmed in New York. The pilot episode premiered on October 11, 2006, and seven full seasons have aired since. The series' supporting cast includes Alec Baldwin, Tracy Morgan, Jane Krakowski, Jack McBrayer, Scott Adsit, Judah Friedlander, Katrina Bowden, Keith Powell, Lonny Ross, John Lutz, Kevin Brown, Grizz Chapman and Maulik Pancholy.
