30 Rock ran for seven seasons. The American sitcom aired on NBC from October 11, 2006, through January 31, 2013, completing a seven-season run centered on Liz Lemon and the fictional sketch show TGS with Tracy Jordan.
The series was created by Tina Fey and produced with Broadway Video, Little Stranger, and NBCUniversal. Across its run, it combined workplace comedy, celebrity satire, absurdist humor, and stories about television production. Its ensemble included Tracy Morgan, Alec Baldwin, Jane Krakowski, Jack McBrayer, and Katrina Bowden.
The seventh season was the final season and consisted of 13 episodes. It concluded with a one-hour series finale that wrapped up the professional and personal storylines of the TGS team. In total, the series produced 138 episodes.
Some viewers remember discussion of a possible eighth season, particularly because Alec Baldwin publicly supported extending the show. However, that possibility never became part of the broadcast series: seven seasons is the canonical total.
