Technological Diffusion
Captions available
The idea
Technological diffusion is the spread of technology across national borders, moving unevenly from where it originates toward nations with less infrastructure to receive it.
In practice
A vaccine technology developed in one country reaching manufacturers in another illustrates diffusion carrying an innovation past its origin point.
Where people slip
Diffusion describes technology's movement, not its equal arrival; infrastructure and investment still concentrate access geographically.
