I have been trying to find statistics on the pattern of sales of
various technologies to the consumer market from the date of
introduction to the current year.  What I want to do is to chart
the various curves, relate those curves to technology that is
being developed and/or has recently been introduced.  The resultant
charts will be used to provide some framework for budget planning
in our large school district.

For example, what did the sales curve of color television look
like and can it be used to plan for the obsolescence of NTSC in
our schools when HDTV becomes a consumer product?

Any pointers toward appropriate sources of information will be
greatly appreciated!
