So you're imagining something like idol culture taking over? I could see that happening. Hololive is the current major successful one. I the old "new media groups" all failed because they still relied on some element of these individuals as major organisers and the organisational structure to self-perpetuate and bring up new icons was never constructed, once they aged up they got bored because they didn't need more money and never adapted to changing trends because they were comfortable just playing games.

I could see that happening but I have not yet seen a western company with the organisational capacity to not fizzle out. Eastern companies oriented around idol culture do much better with this.
