My youtube channel gets lots of views a month at the moment (almost at the 60 million total views). I am noticing when uploading my videos there is a distinct push of Oculus Quest adverts. I assume this is part of a massive marketing campaign leading up to the holiday season. The ad is pretty neat and showcases the basics. Oh on the flip-side, I have seen zero Rift S ads on Youtube, but some through Google but that doesn't count because that's probably based on my web usage.
