This kind of analysis leads to a different perspective I refer to as the ``Oh Well'' view. Rather than continued exponential growth, the trend continues until it begins to encounter limits that constrain it, then it tapers off after achieving maturity.
This view is very popular among mainstream business analysts since, especially if you cook up some suitably bogus constraints, you can always justify cutting research and development, reject innovative market expansion and distribution ideas, and relegate the business to a mindless caretaker status once it has reached ``maturity''.
For example, once you've sold a video tape recorder to every TV station, how many more could you possibly sell?
