What's with TV these days?

ok So my girls where watching the tc channel Treehouse the other day. On came this show called In the Night Garden. It looked good so I sat and watched for a few minutes. Oh my, I have to just shake my head! These were some kind of alien/child things in bright colours who can't talk they make this weird garble sound and that is supposed to be talking? Where did the shows that taught you words and numbers go?

Why is everything in "Baby Talk" now? Teletubbies where the same.. they would speak in baby talk and not really teach kids anything!

It's seems like it's the tv shows that are teaching our children, and not the parents. I just think that if you are going to allow your children to watch tv.. then it should be educational ones. I used to think that Treehouse was a really good channel for my girls to watch... now I'm not so sure.
