PBS videos have come to iTunes. 

Free? Yup
Good? Check.
Available? Yes.
Accessible on a multitude of devices? Yarp 

When people ask me “How does technology make a difference in the actual education of our kids?” I often stress multimedia.  That is, using multimedia enlivens and enriches ideas in a way normal media can’t. I’m aware of other multimedia sites, (you tube, this list, and of course google), but nothing beats PBS for sheer quality.

This is great, great news.
