Dealing with life in a studio at NBC's 30 Rockefeller Plaza (the title is a shortening of that), 30 Rock centers around Liz Lemon, played by Saturday Night Live's Tina Fey, who's the head writer of The Girlie Show. When her old boss dies and a new boss comes in (Alec Baldwin as Jack Donaghy), demanding the addition of a volatile former movie star (and re-branding the show TGS with Tracy Jordan in the process), Liz must figure out how to keep things running smoothly without losing her mind. 30 ROCK is one of the most popular comedies in the US these days which has won many nods in writing and acting from Emmy Awards and Peoples’ Choice Awards.
