Back in 2016, Valve partnered with HTC to create the Vive, a SteamVR headset to compete with the now-Facebook-owned Oculus Rift. A year later, they released the Vive Pro, an updated headset with better specs. Today, Valve is announcing its own headset, the Valve Index, that aims to push the boundaries even further than its previous offerings with HTC.
