Why did Nick make a teenage version of the Rugrats?

Dude calm down, ALl Grown up is NOT that bad if you actually watch it, it had the same writers and it was cute. It's still 100 times better then the garbage they come up with today. But i do agree that they should make more shows like they used to...and i would still say Nick does WAYYY better then Disney...like i hate all that Hanna Montana, Wizards of Waverly, Two boys living in a hotel and all that GARBAGE the kids i babysit make me watch. At least Nick is still cartoons...
