The sound comes from The Elder Scrolls V: Skyrim, the open-world role-playing game released by Bethesda in 2011. Inside the game it accompanies changes to the player's journal, so millions of players heard it repeatedly while exploring quests across Skyrim's world. As gameplay clips, streams and memes spread online, the chime became shorthand for any small achievement or update, even outside gaming. Its continued popularity comes from that shared recognition: one short tone can tell an audience that progress has been made without any explanation.
