With the exception of Daria, some internet series, and a few anime, teenagers are often a really underserved market in animation. Teen dramas and sitcoms are everywhere on TV, but hardly anyone has the balls to make a cartoon sincerely aimed at teens. It's a shame too, because if all the manga drawing and stick figure doodles in high school will tell you, it's that teenagers love cartoons just as much as young children and adults do. I think TV executives still think that teenagers just aren't interested in cartoons and animation, or think they're too old for that. That's not true as SpongeBob, Adventure Time, Regular Show, My Little Pony: FiM, Family Guy, American Dad, South Park, Avatar, Ninja Turtles, and most Adult Swim content all have a huge following amoung teenagers. I'm a teenager, and I'm a huge fan of Cartoons and animation. If people can make plenty of cartoons aimed at adults, then they should be able to do the same with adolescents.
