As for a robust animation market, what are you thinking of in particular? If it's on premium cable, then subscriptions would be generating income in addition to advertising, yes? (Though, to be honest, I have no real idea how that breaks down.)
Yeah, me neither. I have in mind shows like Avatar: The Last Airbender
and its spin-off (kid-friendly, but as I know from trying to find toys based on them for my niece, they definitely weren't running on toy sales), or in a different register, shows like Archer
or The Venture Bros.
