[EX Q]: Seinfeld is an American sitcom that ran for nine seasons on NBC, from 1989 to 1998. It was created by Larry David and Jerry Seinfeld, the latter starring as a fictionalized version of himself. Set predominantly in an apartment building in Manhattan's Upper West Side in New York City, the show features a handful of Jerry's friends and acquaintances, particularly best friend George Costanza (Jason Alexander), former girlfriend Elaine Benes (Julia Louis-Dreyfus), and neighbor across the hall Cosmo Kramer (Michael Richards).
