Google's last surviving VR product is dead. Today the company stopped selling the Google Cardboard VR viewer on the Google Store, the last move in a long wind-down of Google's once-ambitious VR efforts. The message on the Google Store, which was first spotted by Android Police, reads, "We are no longer selling Google Cardboard on the Google Store."
Google Cardboard was a surprise hit at Google I/O 2014 and moved the entry point for VR lower than anyone had imagined previously. The device was a literal piece of cardboard, shaped like a VR headset, with special plastic lenses. Google built a Cardboard app for Android and iOS, which would let any suitably high-end phone power the headset. The landscape display split into left and right views for your eyes, the phone hardware rendered a VR game, and the accelerometers did 3-DoF (degrees of freedom) head tracking. There was even a cardboard action button on the handset that would boop the touchscreen with a capacitive pad, so you could aim with your head and select options in a VR environment. Since the product was just cardboard and plastic lenses with no electronics whatsoever, Google sold the headset for just $20.
After cardboard, Google started to scale up its VR ambitions. In 2016, Google also launched an upscaled version of Google Cardboard, the Google Daydream VR headset. This was a plastic and cloth version of a phone-powered VR headset, with the key improvements of a head strap and a small controller, for $80.
Next, Google started to pile on software support. VR support also was built into Android 7 Nougat in 2016, allowing Google to make latency-reducing graphics pipeline improvements in the core OS. Google started certifying devices for enhanced "Daydream" support, laying out best hardware and software practices for VR. Android got a VR home screen and added a special notification style so apps could still alert you in the 3D VR interface. A VR version of the Play Store let users download the latest VR experiences in 3D. VR support came to YouTube and Google Street View, and together with Mozilla, the Chrome team launched WebVR. Google's best app was Tilt Brush, a killer piece of VR painting software.
In 2018, Google even roped OEMs into making standalone Daydream VR hardware, so instead of being powered by a phone, Android and all the usual phone bits were integrated into a standalone VR headset. The first one announced was the Lenovo Mirage Solo.
