Seinfeld premiered on NBC in 1989 and ran until 1998, with composer Jonathan Wolff creating its distinctive musical language around sampled slap bass. Instead of a traditional theme with lyrics, the show used short bass interludes tailored to Jerry Seinfeld's stand up openings to move between scenes. Those transitions became one of the most recognisable sounds in television comedy. Online, the riff was isolated, shared on soundboards and in edits, and reused as shorthand for a witty cutaway, a time skip, or a joke that needs no explanation.
