According to this model, which is borrowed from the physical sciences, the diffusion of innovations is a function not only of the distance from one point to another, as with the wave model, but of the population density of areas which stand to be affected by a nearby change. Changes are most likely to begin in large, heavily populated cities which have historically been cultural centers. From there, they radiate outward, but not in a simple wave pattern. Rather, innovations first reach moderately sized cities, which fall under the area of influence of some large, focal city, leaving nearby sparsely populated areas unaffected. Gradually, innovations filter down from more populous areas to those of lesser population, affecting rural areas last, even if such areas are quite close to the original focal area of the change. The spread of change thus can be likened not so much to the effects of dropping a stone into a pond, as with the wave model, but, as . . . to skipping a stone across a pond.
