This paper employs qualitative historical artifacts and a cliometric model to analyze data spanning 97 years – from the launch of Popular Science Monthly magazine (1872) to the moon landing (1969) – in order to assess the ways in which society signals demand-side preferences for a greater quantity and diversity of entrepreneurship. In one of the first expansive empirical analyses highlighting societal demand for entrepreneurship, I identify demand-side signaling mechanisms that fuel increased entrepreneurial activity. Through this, my study provides compelling evidence that latent demand-side forces serve as a generative mechanism of innovation and entrepreneurship, not simply a selective mechanism.
