The company developed the sandbox massively multiplayer online role-playing game "Wurm Online" and its standalone version, "Wurm Unlimited". Code Club AB was founded as Mojang Specifications AB by Rolf Jansson and Markus Persson in 2007, as the game started to turn a profit. Later in 2007, Markus Persson stepped out of the project and left the company, however, he wished to retain the "Mojang" name for himself, because of which Jansson renamed the company Onetoofree AB.
Markus Persson was released on 18 November 2011. Persson left his job as a game developer to work on "Minecraft" full-time until completion. In early 2011, Mojang AB sold the one millionth copy of the game, several months later their second, and several more their third. Mojang hired several new staff members for the "Minecraft" team, while Persson passed the lead developer role to Jens Bergensten. A version for Android and iOS, the "Pocket Edition", has also been released. An Xbox 360 edition of "Minecraft" was released on 9 May 2012. The Xbox edition features updates including a tutorial and skin packs.
