The International Data Corporation (IDC) conducted a study into 2018's decline in the number of VR headsets sold. First they found that many of the screenless viewers that were bundled with phones have been discontinued and they accounted for a large portion of the market. Tethered headsets like the Oculus and Sony units haven't received discounts in 2018 to boost their sales like they did in 2017. This led to a 37.3% decline in the tethered market but HTC still managed to sell 111,000 units because of their subscription plan and Pro headset release. The VR market is expected to rebound as standalone devices are just getting their legs and more commercial headset sales occur that allow consumers to test VR for the first time. Standalone VR headsets grew 417.7% during the quarter, largely due to the global availability of the Oculus Go/Xiaomi Mi VR, which managed to ship 212,000 headsets. While the consumer side of the VR headset market remains the focus of attention, the commercial side has seen pilots and large- scale deployments gaining traction. In 2Q18, roughly 20% of VR headsets were destined for the commercial sector, up from 14% in 2Q17. Along with the increase in share, average selling prices (ASPs) have also increased from $333 to $442 during the same period.
