Innovation landscapes: The changing role of corporate research
Corporate laboratories were hotspots for U.S. innovation for most of the twentieth century. Large firms, such as DuPont or Bell Labs, acted as epicenters for research and development activities, driving investment in frontier technologies underserved by university researchers at the time. By the 1980s, however, many of these powerhouses of industrial research began to cut back on their research programs, paving the way for universities and startups to emerge as new centers of innovation.
