Hmmm, with the professional media organisations it all boils down to providing a medium for selling advertising. The big media companies pump the big bucks into production values (sets, cameras, writers, actors, sound, editing, graphics, etc) and expect to realise a profit from advertising for these serious efforts. Usually the set designers, camera operators, writers, musicians, editors, and even actors are at the top of their game.
Youtube/Insta-whatever are for rank amateur wannabies, and the companies behind those products know that very well and are only concerned about their cut and couldn't care less what crap you post, they may even offer you a token stipend for your efforts. There are enough narcissist/wannabies out there in the world to keep this business model afloat making decent money for these companies with minimal outlay.
A real job will better in the long run.
