Cartoons?

Whatever happened to Saturday morning cartoons? It used to be all you could watch on most networks from like 7am-3pm every Saturday, but now you're lucky if they show any at all. What the hell happened to the idea of entertaining kids with cartoons on the first day of the weekend? I remember when I used to get so excited for all the shows on that day, the way I get excited for a Sunday of NFL nowadays. It's sad I think, and a lot of kids today are missing out on what was really a staple for anyone in my generation.
