Understood as the subsequent adoption and spread of the innovation as a product.
One mechanism for diffusion would be adoption of the innovation by
consmers of that innovation
Reasons for diffusion
A product would be diffused if there was a clear indicator
that it would reduce the cost of human labour, or speed up
the process in which a task can be completed.
Adoption could be motivated in a market economy, by reduced
costs for similar products or processes
Enhancement of human capacities, as a result
Problems with adopting at the diffusion stage
(Marx, 1976, p.530) identifies that when a product “…comes into general use”
the “surplus-value does not arise from the labour-power that has been replaced”
but the true competitive advantage comes from “the labour-power actually
employed” in using the technology in a more efficient and effective way
compared to their competitors.
Not the word processor, but the people using the processor make the difference.
Simply owning the product does not give the user a competitive
advantage, but through the way that it is utilised.
Example
As the smartphone diffused, it was not enough to
just own the smartphone to achieve a competitive
advantage, the surplus-value had to come from the
way the user utilised the technology in an efficient
and effective manner to gain a true competitive
advantage.
Successful
The time from innovation to diffusion for the smartphone was
substantially shorter than the original mobile phone, as the technology,
mobile network infrastructure and the demand for such a device already
existed and this led to the highly successful diffusion of the smartphone
which is still ongoing today.
Reinvention
The invention of "uses of technologies" not anticipated
by designers, have often been central to the vitality of a
technology's development
Ship radio not initally intended for music and talk shows
Positive effects of diffusion of information technologies
Technological processes substituting for direct human mental labour
Substitution of fixed capital (machinery) for labour
Greater efficiency in production and enhanced capacities
Enhancement of human labour
Labour saving costs
Communal, not universal, labour is invested in the diffusion of
innovations, by purchase or other forms of adoption
