It is clear that IBM had the lowest proportion of staff participation in early stage, but its figure overtook those for the other competitors by 2010. Similarly, the figure for Microsoft saw an upward trend, eventually surpassing those for Apple, but not as much as IBM.

In 1980, merely 2% of IBM personnel participated in the position, which was the lowest proportion. By contrast, Apple had the most participating employees’ rate, at 15%, while the percentage for Apple stood at just under 10%. By 1995, IBM saw a dramatic increase in the percentage, reaching 25%, which overtook the proportions for Microsoft and Apple. In the meantime, the male participation rates of Microsoft and Apple rose by 5% and 6% by the same year, respectively.

From 1995 to 2010, the figure for IBM soared more than twice as much as in 1995, to a peak of 63% in 2010. Likely, Apple saw a substantial rise in the percentage by 30%, while Apple only experienced a relatively slight increase to 25% over the same period.
