Any sort of channel I could run would never get the funding necessary to survive past the first month or so due to shitty execs not be willing to run adds on it.
But, provided somehow I just came into vast enough wealth for that to never be a problem, I'd do some shit.
I'd show pilots new and old, and let the audience vote in on which shows get to continue airing in a timeslot, mostly modern shows, in addition to some older cartoons from back in the day that could air either a little earlier or a little later in the day.
I'd also like to reserve some time for an interview show where we bring on animators and show runners, both independent and not so independent, and shoot the shit about the current state of the industry and whatnot.
My channel would be something akin to AMC, in terms of what's allowed to be shown, for western animated entertainment. I'd like to make a push to age up what's acceptable to show in animation, allowing for more adult oriented shows that don't have to be Macfarlan tier unfunny garbage.
I'd also like to sign on Zone and a team of his choosing to make official pornography for the channel, and kickstart the western Hentai business.
