I think these things are a disaster and I hope they fail. It is a pretty cruel thing to say, but it's what I want.
I know they think with these shows they can get more younger viewers, but I think that is all they are going to get. I mean, you can get teens and adults to watch shows like Chowder or Flap Jack, but you won't find them ever liking Hanna Montana. Those kind of shows are hyper focused on the pre-teen and under demographic that they will get a lot in that group, but that will be all they get.
Personally, I find targeting for certain demographics as the highest priority as a horrible idea. It can grow audiences, but in turn it alienates your other audience at the same time. It also can have a wall effect, suddenly kids in High School dislike Hana Montana who once liked it, or they grow out of it, etc. That is a big red flag in my book.
They've also seem to have given up completely on teens. Sure there is adult swim, but Teens should not be watching Adult Swim (because that can lead to the censorship of Adult Swim programming) Plus having the reality tv shows (I believe they are all reality TV shows) is the worse possible situation for fans that want quality programming and cartoons. Reality Shows are cheap and easy to make and don't require many fans to be a hit.
This is kind of just some wild rant, but I really, really, really hate what Cartoon Network has become, and I notice that I only watch 10% of what I normally would watch 10 years ago (and that has nothing to do with changing taste or time). I know they've been having trouble with ratings, so maybe that is a reflection of what they should be worrying about.
