The term "secondary products revolution" is often used to describe the increase in non-food items produced by early agricultural societies. However, there are several synonyms for this term that can be used to describe this historical phenomenon. For instance, the "industrialization of craft production" highlights the shift from handcrafted goods to machine-made items. Other terms include "technological innovation in manufacturing," "diversification of product output," and the "rise of material culture." Each of these synonyms offers a slightly different perspective on the increase in secondary product production during the agricultural revolution. Nonetheless, they all speak to the profound economic and societal changes that occurred during this period.
