I think it needs to market towards every demographic. And I mean EVERY demographic. That means boys, girls, little kids, preteens, teens, college students and adults. Why is Nickelodeon so successful? Because it has Nick Jr. - for the little kids, regular Nickelodeon - for kids, preteens and teens, and Nick @ Nite - for adults.
It doesn't need live action or reality shows, it needs more shows in general to market toward different audiences. Right now CN is marketing toward young and tween boys, and that's about it. If they get some shows in for young and tween girls and teens, they'll have it made, since they got Adult Swim for the college crowd and adults.
I know they're supposed to have Boomerang for this but I really think they should air old stuff again, even if its 80s shows. Rerun some Jem and Holograms or My Little Pony for the girls, dammit!
Also what's wrong with rerunning the 90s shows? There's gonna be more kids who've never seen it and older people who saw it as kids and still love watching it for the nostalgia. Bring back Powerpuff Girls and some of those shows!
Woo... that kinda turned into a rant. Oh well!
