Nothing in contemporary America matches the impact of a megahit television program as it works its way into the habits and vocabulary of the audience. The impact is not simply demographic or economic, but truly cultural, as a program influences the vocabulary and style of its fans. Such a phenomena was Seinfeld, which ran on NBC from 1989 to 1998 and introduced America to the situation comedy of four friends just trying to get by-usually unsuccessfully-in modern-day Manhattan. Playing the deadpan ringmaster of Elaine, George, and Kramer's misguided antics was Jerry Seinfeld, a stand-up comedian whose observational humor about the absurdities of modern behavior was perfect for Seinfeld's satire of yuppie Americans. Sharp and acerbically written, the show contained catch-phrases ("Yadda, yadda, yadda," "master of your domain") that soon became commonplace. In various polls, Seinfeld is considered one of the greatest television programs of all time.
