Disney gets the new landscape. They give early access to tons of youtubers and you can't move on yourtube without bumping into the latest breakdowns, rections etc about an episode of moon knight or a teaser trailer, shows are released globally within hours, and they have a massive back catalogue.
Amazon bought MGM, bringing in things like Stargate and Bond, but it's dabbling, if their video service stops, it doesn't really cause the company to fail. Apple doesn't seem to know where it wants to go, it's not really in the game, but it's not their core competency either.
Netflix had an opportunity to secure their catalogues a couple of years ago, but just threw money at trying to create original content but not really knowing how (and certainly not knowing how to do it efficently)
