The bar chart gives information about how many apps were sold in three different stores, namely the IOS App Store, Google Play and Amazon Appstore over a 4-year period between 2010 and 2014.
Overall, what stands out from the graph is that the number of apps in all stores sold increased significantly over the period, with the biggest rise being in the final year. Additionally, at the beginning of this period, while the IOS App Store was the shop which sold the most apps until 2013, It was overtaken by Google Play in the final year. However, both shops sold significantly more than Amazon appstore.
At the beginning of the period, the IOS App Store dominated the market with sales of just over 160 thousand apps. At the same time, while Google Play had almost no apps in the first year, it too saw a steady rise, finishing at just under 750, 000 in 2013. However, by 2014, sales of apps at Google Play had surged to overtake those of the iOS App Store, with the former recording roughly 1, 400, 000 sales and the later just under 1, 250, 000.
As for Amazon Appstore, it was not represented in 2010, only entering the market in 2011 at a very low figure. Sales then grew very slightly over the next two years, but like the other two shops, rose more in the final year, ending at just over 250, 000, which is the same level as the iOS store’s in 2011 and Google Play in 2012.
