“In a sense Ford was both the most brilliant and the most senseless marketer in American history. He was senseless because he refused to give the customer anything but a black car. He was brilliant because he fashioned a production system designed to fit market needs. We habitually celebrate him for the wrong reason, his production genius. His real genius was marketing. We think he was able to cut his selling price and therefore sell millions of $500 cars because his invention of the assembly line had reduced the costs. Actually he invented the assembly line because he had concluded that at $500 he could sell millions of cars. Mass production was the result, not the cause of his low prices.” – Theodore Levitt, The Marketing Imagination
