Those of us who like to stay up to date on the latest technology news are probably abundantly familiar with virtual reality headsets like Google Cardboard and the Oculus Rift, but most Americans aren’t so knowledgeable. On Monday, Horizon Media posted the results of a recent study it conducted, which found that a mere 33% of Americans are aware of the three major virtual reality headsets: Google Cardboard, Oculus Rift, and Samsung Gear VR. This probably has more to do with a lack of advertising than a lack of consumer interest, and that lack of advertising is due to the fact that virtual reality is still very much in its infancy, and it’ll be a while before more consumer-friendly headsets get released.
