From its founding, MIT has been an engine of both local and global economic growth, playing a key role in the creation of thousands of companies and millions of jobs. More recently, MIT sits at the center of an entrepreneurial boom due to an "entrepreneurial ecosystem"—an informal network of groups dedicated to nurturing and encouraging entrepreneurship. This trailer includes highlights from the documentary The Ecosystem: Nurturing Entrepreneurship at MIT, which examines the development of this ecosystem, how it works, and the role it plays in MIT's ongoing commitment to creating innovations that make a difference.
