Microsoft introduced achievements and Gamerscore with the Xbox 360 in 2005, giving players a persistent reward for completing specific in-game challenges and making the accompanying chime a familiar part of gaming culture. As gameplay videos, streams and reaction clips spread on YouTube and Twitch, creators began lifting the sound outside its original context to mark any kind of success. It endures because the cue is instantly understood, even by people who have never owned a console, as shorthand for progress, completion and a job well done.
