Jerome "Jerry" Seinfeld is the main protagonist on the United States television sitcom Seinfeld (1989–1998). The straight man of the group, this semi-fictionalized version of comedian Jerry Seinfeld was named after, co-created by, based on, and played by Seinfeld himself. The series revolves around Jerry's misadventures with his best friend George Costanza, neighbor Cosmo Kramer, and ex-girlfriend Elaine Benes.
He is usually the voice of reason amidst his friends' antics and the focal point of the foursome's relationship. An eternal optimist, he rarely runs into major personal problems. Jerry is the only main character on the show to maintain the same career (a stand-up comedian, like the real Seinfeld) throughout the series.
He is the most observational character, sarcastically commenting on his friends' quirky habits. Much of the show's action takes place in Jerry's apartment located at 129 West 81st Street, apartment 5A. He and his friends also frequent Monk's Cafe.
Jerry appeared in all 180 episodes of Seinfeld (including several 2-part episodes), holding the distinction of being the only character in the show to appear in every episode.
saw him on one of the superbowl commercials and he looked so old....watching Seinfeld and he looks so young - I prefer to remember them the way I see them on TV - jmo
