Sony's Playstation VR has sold nearly 1 million units

"The PlayStation VR was a risky prospect for Sony. As a relatively pricey (£350) add-on for the PS4, centred on technology that's still a niche to the mainstream, it could have been an expensive blunder for the gaming company. Instead, it's been a bigger success than Sony hoped.
Speaking to the New York Times, Sony Interactive Entertainment chief executive Andrew House revealed sales for the VR headset hit 915,000 on February 19.
That figure exceeds what already looked to be a warm reception for the PS4 peripheral. Earlier this month, analytics firm SuperData estimated the PSVR had shipped 750,000 units since launch.
In fact, the PSVR has been so popular, it even caught Sony off guard."
