TV Technology Diffusion Curves
It's rather shocking to give students an assignment to find diffusion curves for media technologies from radio sets to broadband Internet connections because they are amazingly difficult to find. One would expect there is a single source that has this kind of information. Some sample sources include Statistical Abstracts of the United States, Predicasts Forecasts, and industry promotional groups such as the Television Advertising Bureau and the Consumer Electronics Assocaition (CEA). Graphs of growth curves are highly instructive as to where future media may be going. Color TV and VCR growth, for example, initially grew slowly. Personal computers in the home grew even more slowly. DVD players, on the other hand, grew faster than nearly anyone predicted.
