Laugh tracks became a familiar part of radio and television comedy long before internet memes, where prerecorded audience laughter was added to guide the joke. Online, short laugh track clips spread because they are instantly understood even without context. Editors use them across reaction videos, fail compilations, and ironic posts to create a fake sitcom feel in just a few seconds. The sound remains popular because it can either support a genuinely funny moment or make an uncomfortable scene funnier through contrast.
