Philadelphia-based Virtual Reality for Rent, is staying afloat by filling the growing demand for entertainment beyond Netflix. He’s now mailing out about 60 VR Oculus headsets (made by Facebook Inc.) a week to individuals, a seven-fold jump from before the outbreak. The technology allows kids to visit carnivals, while twenty-somethings can dance at a club with strangers from around the world.

“Kids don’t go to arcades anymore, but they can go to VR arcades,” said Dunning, who is now offering rentals as low as $35 a day.

Alex Gerasimov, owner of the VR Zone DC, is seeing a new wave of interest, too. His company is now working on a new offering for Birthday Parties in which VR headsets are sent to as many as 10 homes. Attendees then create avatars and compete in multi-player games, like bowling and dodgeball. The event could end with singing “Happy Birthday” and some virtual cake.

This is why you can't find headsets right now.
