The document traces the emergence of entrepreneurship from pre-industrial to post-industrial eras. It discusses how entrepreneurship began with trade and the agricultural revolution before the industrial age fueled a shift to large-scale production. The industrial revolution introduced new sources of energy and available labor that changed small-scale production. Surveys found that early British innovators during this period came from manufacturing, artisan, and peasant backgrounds. Entrepreneurship continued evolving after World Wars and is impacted by economic, social, and psychological factors that drive people to address demand through supply.
