3. Oculus

Oculus VR began in a garage in Irvine, California, in June 2012. Then-19-year-old Palmer Luckey launched the company on Kickstarter, raising nearly $2.5 million for his virtual reality headset. After raising an additional $16 million in funding, Luckey sold Oculus to Facebook in 2014 for $2 billion.

Now, Luckey has left Oculus, but the VR company lives on at Facebook. Oculus currently offers three headsets: the Rift S, Quest, and Go.
