In 1989 the NBC sitcom Seinfeld aired its pilot episode, then under the title The Seinfeld Chronicles, in a dump slot during the middle of the summer. The ratings were low and the show seemed to go almost unnoticed to all, except for a single executive at NBC who believed in the series enough to convince the network to produce four more episodes to round out what would be an unusually short first season. Nine years later its series finale would air, reaching the staggering number of 79 million viewers. In the course of a nine-season run Seinfeld became one of the most influential sitcoms and a true cultural phenomenon, continuing its comedy dominance even over the ten years since it ended. With the obsession of the minutiae, an increased focus on story structure, and love of meta, self-referential humor Seinfeld changed the notion of what Americans knew to be a sitcom and helped pave the way for the single camera comedies of today.
