ABSTRACT
The case of PC software illustrates very nicely the two polar extremes identified in the theoretical discussion and the previous case studies. This may seem surprising, for a perusal of the current PC software market suggests that it is dominated by large players, and that mergers are the order of the day to remain competitive. Looked at over a ten-year period, however, the software case does illustrate both the concentrating effects of rapid incremental change and the deconcentrating effects of radically new software product categories.
