The sound comes from World of Warcraft, Blizzard Entertainment's long-running online role-playing game, where it plays at the end of a player-versus-player battleground when the Alliance faction wins. Players have heard it for years after matches in battlegrounds such as Warsong Gulch and Alterac Valley, and its association with a hard-earned team victory made it familiar well beyond the game itself. Clips of the fanfare are now widely reused in gameplay montages, streams and reaction videos, where it instantly signals an Alliance win to other players.
