Despite a handful of devices and years of sales, Facebook has never shared unit sales of any of their VR headsets.

Today, Oculus released a new sales figure as the company reaches the 1 year anniversary of the release of the Quest headset. We didn’t get unit sales but the company did share that they’ve sold $100 million worth of Quest content in the device’s first year — a number that indicates that while the platform is still nascent, a handful of developers are definitely making it work for them.
