Markus "Notch" Persson (born June 1, 1979) is a Swedish video game programmer and designer. He was the owner of Mojang AB, but he sold Mojang to Microsoft on September 16, 2014 for 2.5 billion dollars. He said that he didn't want to own it anymore because it was getting too big on a blog post. His main venture for founding Mojang was Minecraft, a first-person sandbox indie game that has gained popularity and support since its demo in 2009. Notch retained his position as the lead designer of Minecraft until the game's official launch in 2011. He then transferred his position as lead designer on Minecraft to "Jeb" so he could work on his own project, 0x10c. However, this project has since been abandoned.
