I have come across a great resource..... Studio 4 Learning .
According the website FAQ:
"What is Studio 4 Learning?
Studio 4 Learning, owned by Studio 4 Networks (www.studio4networks.com), is an ad-supported streaming video network on cable, broadband, and satellite. It is geared toward students from middle school through early college as a way to supplement classroom learning and get ahead on school topics."
F.Y.I. - I want to point out that this is "ad-supported" and the ads are definitely targeted towards teens and young adults. (I'm feeling old!)
There are also two other websites available:
Studio 4 Kids
Studio 4 Fitness
