Introduction Term



The process by which a new idea, object, or practice filters through various channels in a community over time


The new ideas, objects, or practices that are to be adopted


Indicates that this model has been tested thoroughly

•The idea of this theory deals with the dissemination of new ideas and their adoption by people in a systematic manner •It is a tool for social change

•Can be traced back to the 1900s • Gabriel Tarde, French sociologist, wrote The Laws of

Imitation •

Described how innovations (new ideas, concepts, etc.) are accepted

• Georg Simmel, German philosopher, introduced the

concept of a stranger •

A member of a system but not strongly attached to it

•Empirical work began with hybrid seed corn study • Sociologists Bryce Ryan and Neal Gross at Iowa State

University • •

Tried to find out how long it would take farmers to fully adopt or accept the innovation (the use of the hybrid corn seed) Took an estimated 12 years for full diffusion

Historical Background  Popular in rural

sociology from 1940’s to 1950’s  Everett Rogers  Pursued the theory in

Doctorate degree  1962- wrote the book, Diffusion of Innovations 

2003- 5th edition of book

 Foremost authority on

this theory

The diffusion model has now been around for a long time, almost 60 years. Is diffusion dead or dying? It is not declining. The number of diffusion publications completed per year continues to hold steady. Unlike most models of human behavior that begin to fade after some years of use, the diffusion model continues to attract interest from scholars.

An idea, practice or product that is perceived as new

Attributes of Innovation Cost


Perceived Relative Advantage

Conclusion  Summary: Diffusion of innovations deals with adoption of new ideas and practices over a period of time.  Four main constructs: 1. Innovation-9 attributes 2.Communication Channels 3. Time 4. Social System

STRENGTHS  Has existed for over 100

WEAKNESSES  Diffusion occurs slowly  Complex process occurring

across multiple levels and settings  Not very useful for current problems that everyone is already knowledgeable about
