When video tape becomes available to the ordinary household as it will shortly, there will be a revolution in education comparable with that which took place with the coming of the printed book. As long as education depended upon access to manuscripts, it was a very slow and painful process. With the coming of the portable privately-owned printed book, the whole educational process took on a new character. This is going to happen with video tape machines, because it means that anyone can have top-level surgeons, biologists, physicists, philosophers, poets – anything for his own private use on all subjects and at his own time, his own leisure and his open space.
