History

Development

The Valve Index is Valve's first virtual reality headset developed and manufactured in house, and is planned to be the launch console for Valve's upcoming virtual reality games. Development on a completely first party headset started some time around 2015 according to interviews with staff, before the release of their Vive headset with HTC. In February 2021, Valve registered patents for a new VR headset, describing the improvements over the previous model.

Release

It sold an estimated 149,000 sets in 2019, 103,000 of which were in the fourth quarter due to the announcement of '' Half-Life: Alyx'', which buyers received for free. The sudden demand caused the unit to be sold out in all 31 countries except Japan in January 2020. As of December 2019, 6.67% of the VR units connected to Steam are Valve Index sets. While Valve had anticipated supply for many of those that had ordered the Index in time for the March 2020 release of ''Half-Life: Alyx'', the
