Let's face it, kids don't read comic books any more, except for Japanese comics.
So I was wondering, do you think cartoons provide a better gateway for kids into the Marvel Universe, then comics? A cartoon doesn't have some of the problems a comic would, that prevent kids from reading it, ex: content parents may find unsuitable, 40 years of continuity, etc.
Plus a cartoon when done well can improve upon concepts found in a comic, like what BTAS did with Mr. Freeze.
I don't know, but if I hadn't come across season two of the 90s FF cartoon, I probably never would've been exposed to that team.
