AV1 has been around for a decade (well, it was released 7 years ago but the Alliance for Open Media was formed a decade ago).

It's fine that you haven't heard of it before (you're one of today's lucky 10,000!) but it really isn't that niche. YouTube and Netflix (from TFA) also started switching to AV1 several years ago, so I would expect it to have similar name recognition to VP9 or WebM at this point. My only interaction with video codecs is having to futz around with ffmpeg to get stuff to play on my TV, and I heard about AV1 a year or two before it was published.
