It is the fourth released game set in the fantasy Warcraft universe, which was first introduced by Warcraft: Orcs & Humans in 1994.

Blizzard Entertainment announced World of Warcraft on the 2nd of September 2001. The game was released on the 23rd of November 2004, which was intended to be the 10th anniversary of the Warcraft franchise, even though Warcraft: Orcs & Humans was actually released on the 15th of November 1994.

The first expansion set of the game, The Burning Crusade, was released on the 16th of January 2007. The second expansion set, Wrath of the Lich King, was released on the 13th of November 2008. The third expansion set, Cataclysm, was announced at BlizzCon 2009.
