This is a the fascinating story of the oil businesses, from its rough and tumble beginnings in Pennsylvania and Ohio to its status today as the world's most vital international resource. It contains lots of excellent footage and portrayals of key players like John D. Rockefeller. Daniel Yergin's book is the basis of it, and he is interviewed extensively, along with a couple of other historians. This must be a popular documentary, because my local PBS station used to show it during fundraisers. I have been wanting this for a long time and was delighted to see it get released on DVD. So why is it such a lousy copy? It looks it was transferred from VHS tapes or something - images are a little blurry and the colors are way off. Hopefully there will be a better version put out sometime in the future, but for now, at the bargain price of under $10, grab it.
