The coin sound first appeared in Super Mario Bros., released by Nintendo for the Nintendo Entertainment System in 1985, where it played every time Mario collected a coin. As Mario became one of the most recognisable characters in gaming, the short chime travelled with him into later games, cartoons, merchandise and online culture. It later spread through gameplay videos, reaction clips, memes and livestreams, where creators adopted it as shorthand for earning, winning or getting paid. Its simplicity and instant recognition keep it useful decades later.
