Oculus owes a lot of its success to a successful Kickstarter campaign.
Back in 2012, the startup raised more than $2.4 million from 9,522 backers.
As with other Kickstarter campaigns, there were several tiers of "rewards" one could receive for backing the early Oculus headset, like T-shirts and posters.
If you put in $300 or more, you got the very first version of the headset sent to developers interested in making virtual reality games.
Some people put in hundreds more — even thousands.
