Seinfeld ran on NBC from 1989 to 1998, and its scene transitions were marked by short bursts of slap bass composed by Jonathan Wolff, a sound that became as recognisable as the show itself. Because the riff was used dozens of times per episode, viewers learned to associate it with a sudden change of location or a comic beat. As clips circulated on YouTube and later TikTok, editors lifted the transition for their own videos, using it to imitate the sitcom format. It remains popular because it instantly signals a sitcom cut without needing any dialogue.
