Professor Rogers begins his book by really getting to the heart of the matter. "Getting a new idea adopted, even when it has obvious advantages, is often very difficult," he writes. "Many innovations require a lengthy period, often many years, from the time they become available to the time they are widely adopted"
I have often wondered why getting new ideas adopted is so difficult, not only in business and technology, which is Professor Roger's primary area of research, but also in the arts, music, painting, and literature. It seems that whenever someone has a really innovative concept, it gets attacked, trashed, savaged, and often sabotaged by the mainstream? Why?
Professor Rogers never really answers this question, and this is my only complaint about an otherwise exceptional book. His primary interest is in figuring out ways to "speed up the rate of the diffusion of an innovation." Within a narrow context of business and policy objectives, he is successful. The strengths of this book are its very competent and exhaustive research, which include case studies, criticisms, and policy discussions. It is a worthy book if you are interested in the focused academic topics it attempts to address.
I thought that Malcolm Gladwell did a better job, with a much simpler book, in explaining why and how new ideas get introduced. Still, many questions remain to be answered about innovations. I'd love to read an equivalent book about innovations in the arts. If we are lucky, someone as competent and as thorough as Professor Rogers will take up the topic.
