After the war, low-cost, highly processed foods became one of the foundational elements of an era of mass prosperity. Many companies in the American food industry developed new products requiring minimal preparation, such as frozen entrees. One such example is the TV dinner in which a multi-course meal was assembled in aluminum packaging in a food factory and flash frozen, then reheated at home in a thermal oven to be served while watching TV. Convenience foods of the era were designed to simplify home preparation.
