Virtual reality was the overwhelming trend to watch in consumer tech this year at South by Southwest in Austin, Texas. 

The technology is fairly new, and some of the most anticipated devices, like the Rift from Facebook's (META 0.90%) Oculus, aren't even in consumers' hands yet, but that hasn't prevented the space from exploding in the past year. 

In this video, The Motley Fool's Dylan Lewis and Rex Moore discuss:

  • How some companies are building out immersive VR hardware.
  • How content providers like Discovery (DISC.A) are thinking about VR content.
  • Why so many booths at SXSW were giving away the Cardboard VR sets made by Alphabet (GOOG 1.31%) (GOOGL 1.25%).
