Diffusion of Innovations (Book)
Rogers's 1962 landmark — revised through five editions over four decades — that synthesized hundreds of studies into the most cited framework in the social sciences for understanding how new ideas travel.
Diffusion of Innovations is the canonical text of diffusion theory. First published in 1962 when Rogers was thirty-one, the book integrated findings from agricultural sociology, medical sociology, marketing, communication studies, and rural extension into a single coherent framework. The fifth and final edition (2003) incorporated forty additional years of cross-cultural research, extending the theory to account for reinvention, the consequences of adoption, pro-innovation bias, and the early effects of the internet. Across its editions, the book built the vocabulary through which innovation research has been conducted ever since: innovators and laggards, relative advantage and compatibility, opinion leaders and change agents, critical mass and reinvention. Its durability has been tested and largely confirmed by the AI transition, even as the framework's boundaries have become newly visible.
