By 1912, just four years after its introduction, three-quarters of the cars on American roads were Model Ts. Ford is often credited with introducing the world to the concept of the moving 'assembly line' in 1913. Though the term may be his, the idea wasn't. For decades, scores of other industries, from vegetable canning to meat wholesaling, had used assembly-line methods, but had referred to them as "continuous process manufacturing" or "flow production." Ford simply adapted the idea to a much larger manufacturing process. With his revolutionary methods, Ford cut the time it took to produce a Model T from fourteen man-hours in 1910 to just two man-hours in 1913, and with that, of course, the price fell.
