When Facebook purchased Oculus VR for $2 billion, both companies stayed fairly tight-lipped about their goals. The money would help Oculus build virtual reality headsets cheaper and better, while Facebook would have a chance to lead the next big computing platform. However, Oculus CEO Brendan Iribe just told an audience at TechCrunch Disrupt about one lofty possibility for the pair: building a massively multiplayer experience for one billion simultaneous users. This is going to be an MMO where we want to put a billion people in VR, he told attendees. While Iribe admits that a billion-person MMO is going to take a bigger network than exists in the world today, he says Facebooks network makes a great place to start, and suggested it could be a Metaverse that joins disparate virtual worlds.
