The pie charts compare changes in the worldwide market share of different computer operating systems between 2012 and 2015.
Overall, while OS 1 experienced the most steady upswing, establishing its consistent dominance in the later three years of the period, the proportion of the ‘others’ sector dipped significantly. Another striking observation is that OS 2 and OS 3 presented the most stable figures throughout the surveyed time frame.
OS 1 and the other unknown system softwares underwent the most considerable changes with contrasting patterns in their market share throughout the period. In 2012, only one-fifth of the computers adopted OS 1, but the figure then nearly doubled to around 40% in 2013 before growing gradually to 52% in the end, indicating a consistent market expansion. Contrastingly, other non-mentioned systems showed decreasing competitiveness as their share kept falling markedly from nearly one-half in the beginning to only 15% in the end.
The percentages of both OS 2 and OS 3 were the most stable among given systems. Starting at 17% in 2012, the figure for OS 2 remained relatively intact when it went up slightly to 18% by 2015. Finally, OS 3 was always last on the list, with the annual sales comprising no more than 15% of the market within this four-year period.
