Teletubbies

What's the deal with Teletubbies. I popped a tape in the VCR for my 1 year old daughter, immediately she sat silent watching Po, La-la, Dipsy, and Tinky-Winky. It's like a sedative to my kids. I'm not sure what the facination is. I guess they like the simple sounds and images. There isn't the typical MTV-like editing which flips from one scene to the next every three seconds.
Teletubbies show a colorful scene with nice calm music on screen for much longer. They also use calming sounds and music, no loud or drastic sound changes. Everything about the teletubbies is calming. I guess that's why they have a calming effect on the kids. Gotta love those Teletubbies.
