World of Warcraft

World of Warcraft is a massively multiplayer online role-playing game developed and published by Blizzard Entertainment, released in 2004 as a continuation of the Warcraft real-time strategy series in a persistent, explorable online world. The game combined broad accessibility, including reduced penalties for character death and structured quest-based progression, with a large, continuously updated online world, features that helped it become by a wide margin the most popular game of its genre, reaching a peak of roughly 12 million active subscriptions around 2010. World of Warcraft has generated more than 9 billion dollars in lifetime revenue and has received sustained developer support and successive expansion packs for more than two decades, an unusually long commercial lifespan that is itself frequently cited as part of the game's historical significance.
