Virtual reality (VR) has become a really, really big thing, and Google has the numbers to prove it.
The company recently reported it shipped five million units of its Cardboard virtual-reality platform in two years. That includes devices that were sold by third-party retailers along with ones given away by Google.
The Google numbers also show that Cardboard has been installed through the Google Play Store more than 25 million times and users have watched more than 350,000 hours of YouTube videos through the app. On the education front, more than 500,000 students have taken VR field trips using the device, according to a report in VentureBeat.
While Google has competition for the VR space, Oculus Rift is still several weeks away from shipping and the HTC Vive is still not available for preorder. And Apple has only just begun to explore the potential of VR, which puts it way behind in the market.
