30 Rock just pulled off a big upset by winning the Emmy for best sitcom. No matter what you think of the result, this represents a stunning improvement over the show's initial start. Let's see why.

I wrote my previous breakdown of 30 Rock after watching their first episode, a big mistake for them and for me. In the first episode, show runner Liz ran all over the city looking for movie comedy star Tracy so he could head the cast of her Saturday Night Live-like show. Sitcoms require a large number of comic oppositions, which play off each other in rapid succession and which can generate comedy for at least 100 episodes. By taking the story out of the studio arena, the 30 Rock writers not only reduced the show to one (fairly weak) comic opposition, they gave the audience the wrong impression of what a typical 30 Rock experience would entail.

Subsequent episodes became much more focused in the studio, and that allowed the writers to generate different comic oppositions between regular characters at a much faster pace. That move alone was worth plenty. But the biggest improvement came from a season-long effort to sharpen the comic differences between characters. The opposition between Liz (played by Tina Fey) and Jack (played by Alec Baldwin) continued to be the primary one, but it improved dramatically. The Jack character is terrific, and Baldwin plays it brilliantly. But if he has no one to work off of, this character is wasted. So the writers sharpened Liz, making her more of a "machine" comic, undercutting the over-the-top "crazies" on the show. Fey also stepped up her game noticeably as a comic actor.

Keeping the stories more within the studio arena also allowed the writers to heighten the secondary comic oppositions. For example, "child" comic Kenneth - the innocent, idealistic and totally naïve page - became a perfect foil for both Tracy and Jack. This was tremendously valuable. Those of you who wish to create sitcoms or simply write a good one, notice that every time you create a new valid comic opposition like this, you get a magnified benefit: the primary opposition doesn't have to carry the whole load, you have more available story turns and the comic density of the show increases.

Another comic opposition that improved over the course of the season was the one between Liz and Jenna (played by Jane Krakowski). The episode that featured Jenna getting in trouble talking about the war in Iraq was one of the funniest of the season and showed that she still has a lot of potential in her oppositions, especially with Jack.

Now that the writers have found their groove, look for the show to focus even more on the in-studio oppositions. 30 Rock may not be the best comedy on television - in my opinion, The Office is a notch above it - but it's one of the funniest in a long time and it's getting better.
