Yes, all media have had to change due to the pandemic, but movie theaters becoming redundant has been happening for a while. COVID just caused the process to skip a few steps forward.
As to production, the traditional method has and will continue to suffer. One thing, though, I'd expect to see is a lot more animation of both traditional and CGI origins. I'd think the biggest area for this to explode is in CGI. Any CGI artist worth their salt has a pretty kick-ass machine at home. And, then, there are services that offer cloud computing for off-line 3D rendering.
All media run on new content.
I expect to see a huge crop of new CGI-based programming in the next few months. That will make that genre more popular and, hopefully, add a lot more adult-oriented content. We don't need more kids shows. The industry has yet to make any truly great, 100% 3D rendered movies and TV shows. The manga stuff is fun, but not great.
But, then, there is another option in the interim: there is a ton of great content on BritBox and Acorn from the UK and Australia that Americans have never seen. You get some of it on Netflix and Prime, but the motherlode is elsewhere.
I've been illegally downloading current content from those countries for several years, but, unless a DVD or Blu-ray is released, older shows aren't really available as usable torrents. If the torrent is older than a month or so, it most likely won't be useable.
So, yes, I've dropped the hammer on both BritBox and Acorn and have a ton of Anglo murder mysteries, crime shows and comedies to watch from the last 30 years.
All of that is new to me.
