Hanna-Barbera was the American animation studio behind classic television cartoons such as The Flintstones, The Jetsons and Scooby-Doo, and its name became shorthand for a whole style of bright, exaggerated cartoon sound. Short laughs like this one were a staple of that era, used to punctuate jokes and silly character reactions in Saturday morning programming. As those shows were shared and remixed online, the laugh survived as a standalone soundboard clip alongside other classic cartoon laughs, valued today because it instantly evokes vintage cartoons without needing any dialogue or context.
