The chart illustrates a comparison of three computer operating systems and others in the global market share over four years from 2012 to 2015. Overall, in three years of this period, OS 1 had the highest market share, while OS 3 had the lowest share throughout the period.
In 2012, unlike other years, other operating systems had the highest market share, capturing less than 50% of the global market. From 2013 to 2015, OS 1 became the most popular, with its market share fluctuating between 38% and 52%.
It is notable that OS 2 maintained a consistent market share over the four years, starting at 15% in 2012 and gradually increasing to 18% in 2015. Finally, despite the large market share of other operating systems in 2012, this share decreased sharply over the next three years, from 48% to 15% in 2015.
