For those of us who tire of witnessing British Petroleum apologize for being in the oil business, or roll our eyes over Chevron PR campaigns dedicated to telling us how we can and should buy less of their product, it may seem that it was always thus. But it was not. Check out this 1956 short film produced by the American Petroleum Institute. Now THAT'S what a self-confident, take-no-guff industry looks like. Someone should tell "Big Oil" to take it's thumb out of it's mouth and start defending their right to exist.
