Seinfeld was an American sitcom that aired on NBC from 1989 to 1998, built around the everyday lives of Jerry Seinfeld and his friends in New York. Its distinctive bass-led transitions, created for the show by composer Jonathan Wolff, were used to bridge scenes without a traditional theme song. Online, editors later lifted those short riffs for memes, reaction videos and parodies, where the sound instantly signals a Seinfeld-style cut. That instant recognition keeps it popular for short-form comedy today.
