Innovation on Tap is the story of innovation in America told through the eyes of 25 entrepreneurs, from Eli Whitney and his cotton gin to Lin-Manuel Miranda and his Broadway smash, Hamilton. The stories illustrate the sweep and impact of innovation. From razor blades, insurance, and baseball to smart cities, online running communities, and cybersecurity, innovators across three centuries gather in an imaginary barroom to discuss the essential themes of entrepreneurship--Mechanization, Mass Production, Consumerism, Digitization, and Sustainability--while emphasizing and reemphasizing the importance of community to their success.
