Seinfeld ran as a popular American sitcom in the 1990s, built around Jerry Seinfeld and his friends in New York, and its audience laughter became closely linked with the show's deadpan, observational humor. Online, clips labelled as the Seinfeld laugh have circulated on soundboards, meme pages and short-form video apps, where creators use them as a quick signal that something is meant to be funny. The sound endures because it instantly evokes classic television comedy, even for viewers who never watched the original episodes regularly.
