This presentation discusses the co-evolution of technological and entrepreneurial developments in new industries, using the drone industry as a case study. It describes how drone technology originated in the military but has since evolved to have new meanings as toys and professional tools. New industries and market segments have emerged as startups explore new applications and established firms enter to protect existing markets or provide complementary elements. The presentation argues that both "de novo" startups and "de alio" new entrants from other industries play important roles - with startups contributing to changing technology meanings and established firms helping build new product categories through cooperation and competition.
