DIFFUSION
is: “The process by which an innovation is communicated through certain
channels over time among the members of social system” INNOVATION is: “An idea,
practice, or object perceived as new by an individual or other unit of adoption.
In
1962 Everett Rogers combined the information flow research findings with
studies about the flow of information and personal influence in several fields
including anthropology, sociology and rural agricultural extension work. He
developed a diffusion theory. So although it is classified as an important
theory in the field of communication, diffusion of innovations there has known
practical application in many other disciplines liked sociology, rural
sociology, economics and medical sociology.
Everett
Rogers in his classic work analyzed thousands of diffusion studies in various
disciplines over the years and found similarities. All the studies involved an
innovation communication form one person to another a society of community
setting and the element of time. Communication Channels: Communication is the
process by which participants create and share information with one another to
reach a mutual understanding. It is also the medium by which messages are transferred
from one individual to another. Mass Media channels such as the internet, TV,
Radio, Newspapers and many others are very effective in creating knowledge of
innovations whereas interpersonal channels like face-to-face, telephone,
instant messaging and many more are also effective in forming and changing
attitudes toward a new idea and thus in
influencing the decision to adopt or reject a new idea.
Time:
It is involved in the innovation-decision process, which is the mental process
through which an individual or other decision making unit passes from first
knowledge of an innovation to forming an attitude toward the innovation to a
decision to adopt or reject, to implementation of the new idea, and to
confirmation of this decision. An individual seeks information at various
stages in the innovation-decision process in order to decrease uncertainty
about an innovation’s expected consequences. Another way time involved in
diffusion is the rate of adoption which is the relative speed with which an
innovation is adopted by members of a social system. The Social System: This is the fourth main element in the
diffusion of new ideas and it is a set of interrelated units that are engaged
in a joint problem-solving to accomplish a common goal. The members of a social
system may be individuals, informal groups, organizations, and/or subsystems.
The social system constitutes a boundary within which an innovation diffuses.
Diffusion
of innovation has helped in so many ways and many societies have undoubtedly
acquired most of their cultural ideas by diffusion. For example, writing, the
use of numerals, mathematics and many others went through the process of
diffusion of innovation.
Diffusion
of innovation theory states that an innovation (i.e., an idea, new technique, and
new technology) diffuses or spreads through out society in a predictable
pattern. A few people will adopt an innovation as soon as they hear of it other
people will take longer to try something new and still others will take much
longer. The pattern is that of an S-shaped curve. The Innovation: This concerns
itself with why certain innovations spread more quickly than other. Rogers argued that the characteristics which
determine an innovation’s rate of adoption are – its Relative advantage,
Compatibility, Complexity, Trial ability and Observability to those within the
social system. Rogers and other diffusion researchers also identified five
separate innovation-adoption categories into which all people in a society will
fall. These are; Innovators, Early adopters, Early majority, Late majority and
Laggards. Diffusion theory is mostly concerned
with the rate at which innovations spread.
