What is diffusion?
1. What is Diffusion?
The information and context behind our link
from diffusion to electric cars. This presentation
shows how we have come to explore how
electric cars have diffused, by firstly
understanding more about diffusion and the
role it plays in society in the 21st century.
2. What is Diffusion?
1)What do we associate with
Diffusion?
2) Diffusion as a “Universal”
definition

3. 1) What do we associate with Diffusion?
Diffusion applies to and is associated with many
different areas, below are several examples.
4. 2) Diffusion as a “Universal” definition
Even though diffusion is a term widely used and associated with many different areas,
it holds the same deep rooted meaning throughout many different contexts. For example,
Brown (1981 p.1) says whilst talking about innovation diffusion that diffusion is “the
process by which change occurs, that is, by which innovations spread from one locale
or one social group to another.”
Mehrer (2007 p.1) describes diffusion (in a scientific sense) by saying,
“If a droplet of ink is placed without
stirring at the bottom of a bottle filled with water, the colour will slowly spread
through the bottle. At first, it will be concentrated near the bottom. After a few days,
it will penetrate upwards a few centimetres. After several days , the solution will be
coloured homogeneously.”
Both of these definitions, although used to describe diffusion in different settings and
within different contexts have the same basis, which is the dispersal of something more
widely.

5. 3) Diffusion and Innovation
Rogers Diffusion of Innovation curve shows where adopters of new
innovations fit into these various different categories. This curve diagram is
also then used to give a visual representation of where an innovation is up
to in terms of it’s diffusion throughout the marketplace.

7. 4) 21st Century Diffusion
Innovations are happening everyday, some are
successful, and some fail. Currently this success or failure of
many innovations is relying upon many of the factors below,
along with many more:-

Culture Community Time
