A classic since its first appearance in the 1980s, this comprehensive reference continues to be the history of the spread of new ideas, for academics and professionals alike. In an age of ever-increasing technological innovation, this renowned volume--which has sold more than 30,000 copies in each edition--is more important than ever. Diffusion of Innovations lucidly explains how inventions and new concepts spread via communication channels over time. As professor Everett Rogers explains, such innovations are almost always perceived as uncertain or even risky. To overcome this, most people seek out others like themselves who have already adopted the new idea. The diffusion process, then, is most often shaped by a few individuals who spread the world amongst their circle of acquaintances, a process that typically takes months or years. But there are exceptions: use of the Internet in the 1990s, for instance, may have spread more rapidly than any other innovation in human history--and it continues to influence the very nature of diffusion by decreasing the significance of physical distance between people. As thought-provoking as it is instructive, this fully updated, widely acclaimed work of scholarship is itself a great idea that continues to spread.
