This document summarizes Everett Rogers' theory of the diffusion of innovations. It defines innovation as the development or adoption of new ideas or technologies. Rogers proposed that the diffusion of innovations follows an S-shaped adoption curve as ideas spread from innovators to early adopters and the early and late majorities over time through communication channels. The diffusion process focuses on how innovations are communicated through social systems and the stages of the innovation-decision process by which individuals adopt or reject new ideas.

3. What is Innovation???
Transformation of an idea into something useful.
There are two different kinds of innovations
1.New things
2.Development of new things

5. Diffusion of innovation
“Diffusion is the process by which an
innovation is communicated through media
over time among members of a social
system”.
Everett Rogers

6. Diffusion and Adoption of Innovation
• Diffusion is a macro process concerned with the
spread of a new product from its source to the
consuming public.
• Adoption is a micro process that focuses on the
stages through which an individual consumer passes
when deciding to accept or reject a new product.

7. Stages in Diffusion of innovation
1. Innovators
2. Early adopters
3. Early majority
4. Late majority
5. Laggards.

11. Innovation
It is any idea or product perceived by
the potential adopter to be new. New
products are ideas, behavior or things
that are qualitatively different from
existing forms.

12. Channels of Communication
• How quickly innovation spread depends on channel
on communication.
• Correct communication channels used during the
process of diffusion, oriented towards behaviour and
preferences of the target category of adopters
• Internet, TV, radio, banners, Sms, News papers, e-
Commerce.

13. Social System
• It is a physical, social or cultural environment in which
people belong and within which they function:
• It can be of two type :
I. Traditional social system
II. Modern social system

14. Time
• Backbone of diffusion process.
• it spread the study of diffusion in three distinct
ways :
1.The amount of purchase time.
2.The identification of adopter categories
3.The rate of adoption.

15. Adoption
• Adoption is a major step in the diffusion
of innovation
• Its is how consumer decides whether try
or not to try and adopt innovative
product/services.

16. Innovation Decision Process

17. CONCLUSION
Diffusion of Innovations seeks to explain how
innovations are taken up in a population. An
innovation is an idea, behavior, or object
that is perceived as new by its audience.
