The sound is best known from The Price Is Right, the long-running American television game show where contestants guess prices and play for prizes. Online, the ding spread far beyond TV clips because it communicates instant correctness in under two seconds. Editors use it as the upbeat opposite of a buzzer, especially in memes, trivia videos and scorekeeping edits. Its staying power comes from how quickly audiences understand the joke: one bright note means somebody nailed it.
