The death of 6-11 action cartoons really was the canary in the coal mine, wasn't it?When they made the purge of action cartoons in the early 2010's, that was when they lost the 6 to 11 demographic. That's when Minecraft/Youtube took their place.
There really is something to be said about just how poorly animation did in theaters this year. Like there were two mega-hits and both of those were based on decades-old IP. It's pretty disheartening. There are some nice suggestions here about diversifying the medium and increased advertising, but there's no guarantee any of that will work.
