It's a bit of a repeat of the early nineties and various companies trying to own the internet. None of it worked until people rallied around a bit of technology that worked based on open standards. Neal Stephenson published Snow Crash around the same time Tim Berners Lee worked on Mosaic, the first proper web browser. One of those things worked. In the years after we had crap like Compuserve, AOL, and others trying to sell off their walled gardens as the Internet. But about ten years later it became clear that the internet really just meant tcp/ip, email, browsers, and all the rest. The lowest common denominator that worked across the thing became ultimately the only thing people wanted.
Of course there have been attempts at open standards for VR. Things like VRML existed 20 years ago and there have been more recent efforts. You can buy VR goggles from a range of vendors and there are lots of games and other things you can use with them. But it's all disconnected stuff and little walled gardens. So, none of that adds up to a coherent web like experience where you can move from one thing to another without leaving your browser just by clicking links.
You can of course run a browser and project it onto your goggles but that seems a bit pointless as the content is almost exclusively 2D. But why is that? Movie producers have been producing 3D movies for ages. Why don't Netflix or Amazon or anyone serve any of that? Reason: standards are missing and there's a huge chicken egg problem of no audience and therefore no content. What little content there is is rotting away in archives owned by companies interested only in walled gardens that don't actually exist. So most of that content is basically unused after it leaves the theaters where people can enjoy it in 3D. And that's just movies.
As long as companies insist on walled gardens, this chicken egg problem is theirs to solve. No content means no users show up and the only people that buy VR goggles are gamers interested in checking out some of the walled gardens.
I hear Apple is about to join this party. They love walled gardens. I don't have high hopes for theirs.
