Walt Whitman Rostow's 1960 model of stages of economic growth describes how societies become modern, industrial economies over five separate stages. The "take-off" stage, which is the third step, describes the moment when societies move toward full industrialization in certain specific ways, such as technological innovations, urbanization, production of secondary goods such as textiles, and intense growth in specific sectors.

Quinary economic activities are sometimes considered as a subset of quaternary economic activities. Other times, they are considered to be an independent group of economic activity. Quinary economics are separate from quaternary because they use collaborative research projects, data analysis, and scientific inquiry designed to improve policy-making of governments and decision-making of corporations. It is an extremely modern branch of economic activity and one that is still being defined.

The Industrial Revolution brought former farmers into the cities to work in factories. These farmers used to grow food for themselves and their families and now needed other ways to get food. Canning foods was a simple solution that made it possible for cities to have access to food.

During the past half-century much of the developed world has experienced a process known as deindustrialization -factories and manufacturing centers have closed down in the United States of America, Western Europe, and Japan and those jobs have been outsourced to the developing world. This has led to the rise of “service-based economies” in the developed world. A “service-based economy” is an economy in which most of the workers are involved in providing services such as research, marketing, telecommunications, innovation, teaching, and so on.

Henry Ford invented the Model-T, the first mass-produced automobile. He also popularized the use of assembly lines and mass production. The concept of the assembly line, and the cheap mass production it provides, is closely associated with Ford to the point where it is sometimes called “Fordism.”
