Google ? I don't know, they have so many products that they acquire and then shut down. Also, they have so many products that... it wouldn't have been such a big deal to acquire Oculus

Microsoft ? They already have a gaming branch so why not, but for the same reason as Google, people wouldn't have noticed it much.

But Facebook ? Everybody around me is going to talk about it, even non-gamers. You have no idea how huge this is for VR.
