When did Henry Ford start using the assembly line?

Henry Ford started using the assembly lin with the production of the Model T Ford in 1908. He developed the concept of revolutionary mass production methods through the use of completely interchangeable parts. By 1914, the assembly process had become so streamlined that it took only 93 minutes to assemble a car. Improved assembly line technique and volume brought the price of the Model T down to about $300 by the 1920s.
