I don't use Twitch, but you've made an interesting point. Microsoft bought Beam, then killed it when it didn't work out.
What about all of the other companies mentioned?
Well lets look
Let's just remind ourselves of the main competitors listed by the CMA, it was: Amazon, Apple, EA, Epic, Facebook, Google Netflix, Nintendo, Nvidia, Sony, Twitch, Ubisoft, Utomik and Valve.
This is quoted from your post that I originally replied to
Amazon has Luna its cloud streaming , it has aws , it has amazon music / video / audible . It has its amazon game studios , it has its own engine that it liscenses out to third parties. It also has a pc program where you can buy games
Apple has the app store , apple music , apple tv , I believe its own audio books / book store. It has apple arcade which is I believe around a 100m users which is more than Xcloud and psn combined.
EA has origin / ea launcher and have EA access as a sub service that you also get a free tier of if you pay for game pass ultimate.
Epic has the most popular engine used by 3rd parties and first parties , it has its epic store on windows pc which pays for exclusives and gives them away for free.
Facebook has its own game video streaming called facebook.com/gaming you can also stream games to play but i think its jsut phone type games. Facebook also owns oculus now and is called meta and is pushing its way into VR with its own gaming platform there
Google has youtube and the now defunct stadia. It has its google cloud service that competes with azure and aws
Nintendo of course has its extremely popular Switch platform which is both a handheld and dedicated console. I believe it has now moved past ps4 in terms of install base doing it in way less time too. They have their nintendo online subscription which includes game streaming of n64 games I believe
Sony has well the second most popular or the most popular console depending on what you consider the switch. They have thier own online sub and their own online game streaming sub which they got from buying gakki and onlive.
Twitch is part of amazon.
Ubbisoft as far as I know just has the Ubisoft launcher on pc.
Utomik seems to have a large selection of cell phone games and pc games to play. it's not really streaming per say , from wht I understand of it you need a computer and what it does is downloads a bit of the game , lets you start to play and downloads the rest as you play. So if you wanted to play a high end pc game you need a high end pc
Valve of course has steam which is the most popular pc gaming platform I think it just broke the record of concurrent users at 27.9m users and there are a a 120m monthly active users which puts its install base above the ps4 and just under the switch I believe . They also allow you to stream yourself playing video games on the platform
They forgot geforce now which uses Nvidia's high end gpus to give you cutting edge pc performance through a stream
If they want to account for twitch , sure its big but look at all these sites like it
