Seinfeld is an American television sitcom that originally aired on NBC from July 5, 1989, to May 14, 1998. It lasted nine seasons, and is now in syndication. It was created by Larry David and Jerry Seinfeld, the latter starring as a fictionalized version of himself. Set predominantly in an apartment block in Manhattan's Upper West Side in New York City, the show features a host of Jerry's friends and acquaintances, in particular best friend George Costanza (Jason Alexander), former girlfriend Elaine Benes (Julia Louis-Dreyfus), and neighbor across the hall Cosmo Kramer (Michael Richards).
Seinfeld was produced by Castle Rock Entertainment in association with Columbia Pictures Television. In syndication the series was distributed by Columbia Pictures Television and Columbia TriStar Television, but Sony Pictures Television has distributed the series since 2002. It was largely co-written by David and Seinfeld with input from numerous script writers, including Larry Charles, Peter Mehlman, Gregg Kavet, Andy Robin, Carol Leifer, David Mandel, Jeff Schaffer, Steve Koren, Jennifer Crittenden, Tom Gammill, Max Pross, Charlie Rubin, Marjorie Gross, Alec Berg, Elaine Pope, and Spike Feresten.
A critical favorite, commercial blockbuster and cultural phenomenon, the show led the Nielsen ratings in its sixth and ninth seasons and finished among the top two (along with the NBC's ER) every year from 1994 to 1998. In 2002, TV Guide named Seinfeld the greatest television program of all time. In 1997, the episodes "The Boyfriend" and "The Parking Garage" were respectively ranked #4 and #33 on TV Guide's 100 Greatest Episodes of All Time. And in 2009, "The Contest" was ranked #1 on the same magazine's list of "TV's Top 100 Episodes of All Time". E! named it the "number 1 reason the '90s ruled."
