ABOUT THE AUTHOR

Minecraft is a sandbox video game developed by Mojang Studios. The game was created by Markus "Notch" Persson in the Java programming language. Following several early private testing versions, it was first made public in May 2009 before fully releasing in November 2011, with Notch stepping down and Jens "Jeb" Bergensten taking over development.
