World of Warcraft, Blizzard Entertainment's long-running online role-playing game first released in 2004, gives its mage class teleport and portal spells that move players instantly between major cities. Those short spell sounds became familiar to millions of players through years of dungeon runs, raids and city travel, and later spread beyond the game as creators clipped them for edits, streams and memes. The teleport effect remains popular because it is instantly recognisable to gamers and communicates fast travel in less than a second, without any dialogue or explanation.
