PBS Kids and NBC Sprout, Stop Showing Dumb Preschool Shows!

PBS Kids and NBC Sprout have a bunch of dumb preschool shows, but there is no educational shows for grade schoolers, middle schoolers, and high schoolers on those channels.
PBS Kids, get rid of Super Why!, Bob the Builder, The Cat in the Hat Knows a Lot, Peg + Cat, Nature Cat, Splash and Bubbles, and Wild Krafts. Make a new version of Where in the World is Carmen Sandiego?, a new version of Where in Time is Carmen Sandiego?, a new game show, Where in the World is Ivy (her last name)?, another new game show, Where in Time is Ivy (her last name)?, a new version of Ghost Writer!
NBC Sprout, get rid of Caillou, Dot., Terrific Trucks, Ruff Ruff, Tweet, and Dave, The Wiggles, The Ollie and Moon Show, The Jungle Bunch, Maya the Bee, The Doozers, Space Racers, and the Super Wings. Put on a new version of Jep!, a new version of Wheel 2000, more Topsy and Tim, and a live action or a cartoon sequel of Where on Earth is Carmen Sandiego with Ivy as the one stealing things not Carmen!
We need educational tv shows for the whole family to watch on TV!
