When was innovation diffusion invented?

1962
Diffusion of Innovation (DOI) Theory, developed by E.M. Rogers in 1962, is one of the oldest social science theories. It originated in communication to explain how, over time, an idea or product gains momentum and diffuses (or spreads) through a specific population or social system.

What is the diffusion of innovation process?

The diffusion of innovation is the process by which new products are adopted (or not) by their intended audiences. It allows designers and marketers to examine why it is that some inferior products are successful when some superior products are not.

Why is diffusion important in technology?

The importance of new technologies derives from the fact that they spread across many different users and uses, as well as different geographic regions. The diffusion of technological improvements, across producers within a country and across international borders, is critical for long run growth.

When was diffusion found?

The first described aspect of diffusion is osmosis – the process of diffusion across the semi-permeable membrane of the solvent towards the more concentrated solution. This phenomenon was first observed by the French abbot Jean-Antoine Nollet in 1748.

How does diffusion of innovation relate to the product life cycle?

The product life cycle is tied to the phenomenon of diffusion of innovation. When a new product comes out, it is likely to first be adopted by consumers who are more innovative than others—they are willing to pay a premium price for the new product and take a risk on unproven technology.

What is diffusion of technology?

Technological diffusion is defined widely as the process by which the market for a new technology changes over time and from which production and usage patterns of new products and production processes result.

Who invented diffusion?

In modern science, the first systematic experimental study of diffusion was performed by Thomas Graham.

Who discovered the process of diffusion?

The first systematic studies of diffusion in gases were probably performed by the Scottish chemist Thomas Graham (1805 – 1869). He is considered as one of the leading chemists of his generation.
