Do not confuse the existence of a technology with its viability as a consumer product.
VR may have been invented in the 90s, but it likely wasn't until a few years ago that we could do it well enough and cheaply enough to make it worthwhile for consumer-level gamers.
VR in the 90s was incredibly low resolution and and had low framerates, not to mention thousands of dollars and with shitty latency. It was ugly and nauseating.
To make VR useable for consumers, it had to be semi-affordable and attractive. It wasn't until the last 10 years as small high-DPI LCD screens dropped in price and PCs could render at the 90+ fps needed to keep latency low (And really, since it's 90+ fps PER EYE, it's really rendering at 180 fps) that VR became viable.
