Seinfeld ran on NBC from 1989 to 1998 and used short slap bass cues to move between scenes, making the sound inseparable from the show's rhythm and humour. The riff, with its improvised, funky feel, became instantly recognisable even to people who had never watched a full episode. As short-form video and meme editing grew, creators began lifting the cue to signal a joke, a scene change or an awkward pause. It remains popular because it instantly sets a light, sitcom-like tone without needing any dialogue.
