Tina Fey created the NBC comedy series 30 Rock.

• Overview: 30 Rock is a sitcom inspired by Fey’s experiences as head writer on Saturday Night Live, with the show’s name drawn from the address of NBC Studios at 30 Rockefeller Plaza. This concept and Fey’s involvement shaped the creation, development, and ongoing production of the series.

• Key people: Tina Fey created and frequently wrote for the show; executive producers included Fey along with Lorne Michaels and others. The cast centers on Fey, Alec Baldwin, and Tracy Morgan, among others.

• Origin notes: Fey pitched the project to NBC after leaving SNL, initially framing it around a cable-news setting before retooling it to resemble an SNL-type behind-the-scenes show. The project was greenlit with an initial 13-episode order and began development in the early 2000s.
