In July 2012, Palmer Luckey, Brendan Iribe, Michael Antonov, and Nate Mitchell founded Oculus VR in Irvine, California. In April 2012, Luckey announced the Rift, a virtual reality headset designed for video gaming, and launched a Kickstarter campaign in August to make virtual reality headsets available to developers. The campaign proved successful and raised $2.4 million, ten times the original goal of $250,000. Two pre-production models were released to developers.
