Virtual reality (VR) has not grown as fast as perhaps some people thought it would, but don't worry, it's not going anywhere, Market research firm IDC says that despite "some unrealistic growth expectations in 2017," VR is still growing and will continue to do so. Meanwhile, the augmented reality (AR) segment is quickly gaining ground.

IDC's forecast calls for the combined AR and VR headset market to reach 13.7 million units by the end of the year, and 81.2 million by 2021 with a compound growth rate of 56.1 percent. The majority of the market will belong to VR, which will account for nine out of 10 headsets until 2019, but AR will pick up steam and claim a quarter of the market by 2021, according to IDC. They will also account for tens of billions of dollars.
