Seinfeld ran on NBC from 1989 to 1998, created by Larry David and Jerry Seinfeld, and its music was composed by Jonathan Wolff. Wolff built the show's signature sound around a sampled slap bass, creating different short riffs to bridge stand up segments and scenes. Those transitions became one of the series' most recognisable trademarks. Online, creators reuse the riff as shorthand for a sitcom style jump in time or place, and it remains popular because audiences instantly understand the joke without any explanation.
