Enzeru, you make sense, but Avengers: Earth's Mightiest Heroes had 847,000 total viewers while Avengers Assemble had 699,000 total viewers. Ultimate Spider-Man hasn't even topped EMH's ratings, yet. They don't want to broaden their audience. They just want to sell toys to boys and that's what their new cartoons are doing.
I don't understand how this will help Marvel when they are serving dumb downed products. These kids will grow up in a few years and think these shows are lame. It's bad enough you can't learn anything from the Marvel Universe like I did from EMH. These shows don't make me want to buy a comic. They make me want to turn off the tv.
Ratings aren't as important as it seems. The show can suck as long as kids buy the toys. Which is why Young Justice gets cancelled even though it's clearly superior to most, if not all of Marvel's animated creations.
