This collection of 10 original essays honors the intellectual legacy of Professor Everett M Rogers (1931-2004), a pioneering and distinguished teacher-scholar of diffusion of innovations, communication networks, and social change. Well-known colleagues and contemporaries write on social change topics that not only piqued Roger’s curiosity, but to which he made seminal and lasting contributions. Overall, this book demonstrates the diversity of Roger’s contributions to the fields of communication science, marketing, organizational change, sociology, and social psychology. Each essay illustrates some of his insights in practice. Together they add up to a stimulating picture of social change approaches which are effective across disciplines, and which will serve as a starting point for future scholarship and practice.
