It is being used in China and India for Streaming. Brazil chose it with LCEVC for their TV 3.0. Broadcasting industry is also preparing for VVC. So it is not popular as in Web and Internet is usage, but it is certainly not dead.
Right, I know some studios have used it for high quality/resolution/framerate exports too, so it is definitely not dead. But still a dead end, from everything I've seen. No one seems to want to bother with it unless it is already within the entire pipeline. Every project I've seen that worked with it that went to consumers or editors ended up running into issues of some sort that they ended up using something else entirely and any VVC support basically abandoned or deprecated. It's a shame because VVC really is pretty awesome, but the only people using it seem to be those that adopted it earlier assuming broader support that never materialized.
I am eagerly awaiting for AV2 test results.
