The ding comes from The Price Is Right, the long-running American television game show built around contestants guessing the prices of prizes. On the show, a bright bell confirms a correct bid, a won prize and other successful moments, making it one of the most recognisable sounds in game show history. As clips and edits spread on YouTube, TikTok and social media, the single ding was lifted out of context and became a shorthand for being right. It remains popular because listeners recognise it instantly, even without seeing the show.
