The show's title comes from a nickname for 30 Rockefeller Plaza, also known as the GE Building, home of NBC's New York City headquarters and studios. 30 Rock is a workplace comedy set in that building and it follows the cast and crew of a fictional sketch comedy show called TGS with Tracy Jordan.
the story:
Typically, the main story arc in each episode centers on Liz and her attempts to steer the show through one crisis or another while she struggles with her social life. 30 Rock typically features Liz Lemon, the head writer of TGS and the show's protagonist, and TGS's producer Pete Hornberger as the "straight" or "sane" ones who must deal with the show's cast of eccentric characters.
The first few episodes of season one mainly involved Liz trying to keep Jack Donaghy, her oily boss, from meddling with her show, though as the season progressed, the character of Jack became less villainous as the show became more focused on its characters' personal lives. The origin of this shift can be traced to "Jack Meets Dennis" in which Jack decides to "mentor" Liz and she reluctantly agrees when she finds she has no better alternative. By this point, Jack seems to have gained some respect for Liz's writing abilities and has apparently ceased trying to alter TGS. Nevertheless, 30 Rock continues to satirize the commercialism of the television industry.
There have also been a handful of episodes in which Liz instead deals mainly with her own weaknesses and insecurities. Liz's love life is particularly unsuccessful and suitable romantic interests have so far proven to be short-lived. The show's self-awareness of this and other sitcom cliches (alternately avoiding and embracing them) has been one of 30 Rock's hallmarks.
the main cast:
you'll like it even if you're not from the states: The show is loosely based on Tina Fey's experiences on the popular NBC sketch comedy, Saturday Night Live and we know that country-specific humor doesn't always translate well. Even more so than Monty Python, however, Saturday Night Live has launched the careers of a large number of comedians and Tina Fey is one of the best writers the show ever had. The show-within-the-show device makes for funny satire about the television industry that surpasses national borders.
Also, in its 2006 year-end issue, Entertainment Weekly listed 30 Rock as fourth on a list of ten best "Series of the Year". In its 2007 year-end issue it was named the #1 show in all of (U.S.) television. In 2007 it won an Emmy for Outstanding Comedy Series.
