I think Saturday mornings have been dead, pretty much since broadcast networks didn't care anymore. I think it's been dead for years. It really started, when Pokemon was dying down in the early 2000's and by about 2005, it was obvious the networks weren't putting much effort into Saturday mornings anymore. ABC Kids, Qubo, and Fox seem to care the least, due to them airing very few, if any, new shows (Qubo does mix their shows, but much of the time, it's bringing old shows back. Fox seems to vary from place to place, but I don't think they put new shows on for E/I all that often). I think the only good broadcast network (which I don't have cable, so bear with me) is the CW4Kids. They actually try to put new episodes on, yet, for some reason, they get beat by ABC Kids, week after week after week (okay, some weeks they won, but it hasn't lasted). I think once the CW4Kids/Toonzai ends (which appears to be very soon, as I don't know how much longer the block will last), the you can stick a fork in them, they're done.
I feel as though kids these days, are too lazy to change the channel. Can't they see that ABC Kids hasn't aired a new episode of Hannah Montana, The Suite Life of Zach and Cody, and That's So Raven in years?

Let alone the fact that some of those shows are done? If I was, a kid, there would be only two options for me. Either watch the CW4Kids or not watch anything.
I know that cable still has some blocks, that get much higher ratings than broadcast. I don't follow those blocks and I don't know much about them. If I had cable, on the other hand, I would probably get up and watch more shows. However, I don't think I would get up at 6 AM to watch Pokemon and 7:30 on weekdays for 5D's.
You can actually research and find many people complaning about how bad Saturday mornings have become. They say, "It's not as good as the older days." I'm just happy I got to see Saturday mornings (though not all of it, due to lessons and things that were going on), before Saturday mornings died.
