Today, at Oculus’ Connect conference, Facebook CEO Mark Zuckerberg announced his company’s ambitious goal for VR growth: 1 billion users.

“We’re setting a goal: we want to get a billion people in virtual reality.” - Zuckerberg, #OC4 — Adi Robertson (@thedextriarchy) October 11, 2017

To say that 1 billion people is a big ask is a serious understatement. Analysts estimate that only a few million VR headsets have been sold across the entire industry, to say nothing of Facebook’s own Oculus Rift hardware, which analysts say may have only sold about a million units as of this summer.

New hardware — like Oculus’ $200 standalone headset — could certainly help with that, but there’s going to be a lot of work ahead before Oculus comes close to hitting that number.
