Login to your YouTube account and go to your studio and in the navigation "videos" has now been replaced with "content." The reason? Expect YouTube and Facebook to allow the uploading of more 3D media (Matterport like material) than they do now by the end of the 1st quarter of 2021. How will this affect the market? YouTube will dominate the media world even more but the analytics they will get, retargeting and ad revenue will be tremendous don't you think? Possibly uploading Matterports?

Facebook now allows you to upload media content directly to private groups which tells me they upgraded their storage and will be heading in the same direction
