Minecraft was developed by Markus "Notch" Persson in May 2009 and led to the establishment of Mojang Studios a month later. The official version was released for Mac and PC in November 2011. By September 2014, it had sold 54 million copies and had 100 million registered users, prompting Microsoft's acquisition of Minecraft and Mojang Studios. Under Microsoft's ownership, the game has continued to grow, with the latest version, Minecraft 26.1, released in March, featuring new blocks, mechanics, mobs, and challenges.
