Facebook is buying virtual-reality company Oculus VR for $2 billion — and the Internet has exploded in response.
Originally introduced on Kickstarter in 2012, Oculus VR's gaming headset Oculus Rift is the biggest development in the virtual-reality space since it was just a dystopian dream. Since Oculus development kits went on sale in March 2013, 75,000 units have been sold — even though the product is not yet available in retail stores.
