The price should be cheap twenty-five or fifty cents. There needs to be some good educational movies with special effects. It would be possible to make several hundred educational movies for a couple of million each. Certainly you could get some directors and studios to work cheap or even donate their time for such a noble cause. You could also put the same movies on video.
Education needs to be simple, cheap, convenient and fun.
An inexpensive way to expose people at home to high school and college classes is to put a camera in each classroom. Then feed the class on an unused cable channel. Cable has hundreds of channels, we could devote a couple dozen channels to every subject imaginable. Tape the lectures to play later at night. A camera today cost under a thousand dollars.
