I can't imagine VR as a whole made anything other than chump change until 2018+, but it was indeed there and chugging along quietly.
The graph specifically calls out the Oculus Rift as the start of what it considers the VR segment.
I would consider things like the Virtual Boy as VR to some extent as well, but I do see the logic as to why they only started the line with the Oculus. Before that it probably wouldn't even show up as the money there was a drop in the bucket of a tenth of a percent of anything else, but it's also widely considered that the Oculus and the Vive were the first really viable commercial VR headsets that started the VR game niche/genre. Before that, VR could probably be considered as niche as eye and head tracking hardware for sim games, and I don't think that I've ever heard somebody mention those when talking about money in the games industry. Or even mentioned them in general outside of conversations like this. I don't think most people even know that that kind of stuff even exists.


I mean, they were at one point urging their admins to "take over other instances and kick out all the non-communists," so...
Plus, there's a reason that Blahaj defederated them. Toxic people will be toxic.
