NBC's 30 Rock may not appear to be a show that pushes any so social limitations or is groundbreaking, but in some ways it is. Tina Fey's character, Liz Lemon, is one that gives a new and refreshing look into what a female character can be in a modern and mass produced sitcom. She may have some antics that are somewhat predictable in a female character on this type of a show, but at the same time she is powerful, in control, and (for the most part) thinks rationally.
For theses who are unfamiliar with the show, Liz is the head writer on a mediocre sketch comedy show for NBC. In each episode a problem eventually arises due to the other writers, the actors, or her boss, Jack (played by Alec Baldwin). Liz is almost always the one who is left to resolve these problems, and even though it sometimes takes a great deal of effort, she almost always is the key to the resolution. That is one way in which this show brings new life into the idea of the female comedic character. She is the strong point of the show. The show is based around her life and career. Not her as a woman, but rather as the head writer of a major network television show. For the majority of the show, the fact that she is a woman is almost an afterthought. It is something that is nearly irrelevant, except for in minor instances.
Jack is another interesting character when discussing gender roles in mass media, specifically the relationship between him and Liz. Despite the fact that he is technically in a higher position then her, Jack is frequently the irrational one and the one to come to outrageous conclusions, while Liz is the one that seems more "normal" and has thoughts that are more collected. Jack is portrayed as someone who worked his way up, but also had a large amount handed to him. Liz, on the other hand, did not have things handed to her. She had to work even harder to get to the place that she it at now. This is not to say that Liz is always reasonable, but no one on the show is.
To truly understand the gender roles in this show one must look at it in the given context. The show is not really based in reality. All of the characters are exaggerated, and at times irrational, but that's why people watch it. Obviously Liz's character does not realistically portray a well adjusted woman, but no character in the show is realistic or well adjusted. Taking into account the exaggerated world that the show takes place in, Liz is a relatively strong female character. She is independent and a substantial positive contributor to the show. She is constantly surrounded by incompetent men, but somehow manages to keep calm, and also fix the majority of the problems that arise on a daily basis.
