The sound first appeared in The Legend of Zelda for the Nintendo Entertainment System in 1986, where it played after Link uncovered secret caves, passages and stairways. Nintendo kept the same distinctive chime in later entries, from A Link to the Past to Breath of the Wild, so generations of players learned to link it with discovery. Online, editors and streamers lifted it as a universal reward cue, using it whenever a real life search, unboxing or puzzle ends with something hidden finally being found.
