I personally think video to be the most effective way to communicate to the masses (especially over books)
Why ?
There are a lot of reasons, but one that matters is : It takes less time for the audience to get the point you are trying to make, and chances are, they would remember parts of it as humans remember pictures more than words!
(on the flip side you end up spending a lot of time making your point, ie. making movies, but i guess that’s ok)

Proof ?
Ask yourself!

Here is how Jeff Skoll is using this powerful mode of communication.
