This kind of ding sound does not point to one single famous source and is widely used as a general-purpose audio cue online. Short bell and chime effects have long appeared in games, user interfaces, quiz shows and editing packs, which helped make the ding sound effect instantly recognizable. It remains popular because it is brief, readable and versatile: editors can use it for jokes, score updates, pop-up captions and small wins without distracting from dialogue or the main action.
