Facebook Inc. spent $2 billion to buy Oculus VR, a maker of virtual reality wearables, in March 2014. Over a year later, CEO Mark Zuckerberg is still trying to justify the deal. With the Oculus Rift headset, which has yet to hit the consumer market, Facebook wants to "give people the power to experience anything," Zuckerberg said during a public Q&A held on his Facebook page Tuesday.

"Even if you don't have the ability to travel somewhere or to be with someone in person, or even if something is physically impossible to build in our analog world, the goal is to help build a medium that will give you the ability to do all of these things you might not otherwise be able to do," Zuckerberg wrote.

This vision is in line with Zuckerberg's push for 3D video, which Facebook's News Feed and Oculus will soon be able to support. The VR headset, among other things, is meant to serve as a communication tool, expanding on the current media options of photos and videos.

Facebook has yet to announce a launch plan for the Oculus Rift, to the dismay of the attendees at its developers conference in March.

But Zuckerberg left little doubt that he has big plans for virtual reality. "Just like we capture photos and videos today and then share them on the Internet to let others experience them too, we’ll be able to capture whole 3D scenes and create new environments and then share those with people as well. It will be pretty wild."
