The development of the moving assembly line created a boon to commerce, enabling industry to produce goods in greater quantity at significantly less cost. The Ford Motor Company refined assembly line methods, resulting in a low-priced car that the average American could afford. Before instituting the assembly line, the Model T sold for $850, taking 12 hours to build. With the new technology, workmen could build a Model T in little more than an hour and a half. By 1916, the Ford Motor Company was selling Model Ts for less than $400 -- the lowest price of any automobile. The success of Ford's operation led to the adoption of assembly line methods by industry, significantly impacting world economies and improving living standards in the 20th century.
