Well probably the people who are interested on this know the name Milton Friedman very well, but I agree that for others an about page would be nice.

Just FYI: this is a television series from Friedmans book "Free to Choose", a classic book that advocates laissez-faire politics (free markets). Highly recommanded if you are interested in economics.

EDIT: Actually I checked and it seems that the book was written after the first TV-series, my bad.
