Minecraft of the alpha version of the game expanded. Persson continued to update the game with releases distributed to users automatically. These updates included new items, new blocks, new mobs, survival mode, and changes to the game's behavior (e.g. how water flows). To back the development of "Minecraft", Persson set up a video game company, Mojang, with the money earned from the game. On 11 December 2010, Persson announced that "Minecraft" was entering its beta testing phase on 20 December 2010. He further stated that bug fixes and all updates leading up to and including the release would still be free.
Mojang initiative started in October 2011, "Mina Kvarter" (My Block), which gave young people in Swedish communities a tool to visualize how they wanted to change their part of town. According to Manneh, the project was a helpful way to visualize urban planning ideas without necessarily having a training in architecture. By 2016, 300 of the areas UN-Habitat plans to remodel will be recreated in "Minecraft". ZeniMax Media, the parent company of Bethesda Softworks, filed a lawsuit against Mojang on 27 September 2011, claiming that Mojang's planned trademark of the title, "Scrolls", infringed upon Bethesda's trademark of "The Elder Scrolls" series.
