The Washington Post today says that left-wingers dominate the business of documentaries–a claim I won’t even begin to challenge (except to note that most documentaries are probably non-political and are watched on the Discovery Channel and its cousins). But the piece probably should have mentioned one of the most important documentaries of all time — Free to Choose, the 10-part television series hosted by Milton Friedman. At the end of the Carter years and the start of the Reagan era, it promoted the concept of free market economics to a huge audience. The medium has in fact worked for the Right.
