Mass production (also flow production, repetitive flow production, series production, or serial production) is the production of large amounts of standardized products, including and especially on assembly lines. The concepts of mass production are applied to various kinds of products, from fluids and particulates handled in bulk (such as food, fuel, chemicals, and mined minerals) to discrete solid parts (such as fasteners) to assemblies of such parts (such as household appliances and automobiles).
The term mass production was defined in a 1926 article in the Encyclopædia Britannica supplement that was written based on correspondence with Ford Motor Co. The New York Times used the term in the title of an article that appeared before publication of the Britannica article. It was also referenced by Sir Chiozza Money, the Fabian banker, politician and author, writing in the London Observer in 1919, comparing the efficiency of mass-production techniques as used in America with British practice.
