Niall Ferguson: The Ascent of Money
This five hour series is not only very informative, it is also very entertaining. Ferguson really "gets it" and I would argue with very little of what he has to say.
This is the history of money and the ascent of man and the West. This is invaluable and everyone should watch it.
