Microsoft operating income by division (2009-2011)
Microsoft operating income by division for the years 2009, 2010, and 2011. Unlike revenue, operating income values vary dramatically from year-to-year. Microsoft Business’s dominance is pretty clear in this chart, as is the amount of money Online Services continues to hemorrhage. Also worth noting is that while Entertainment and Devices represents a small amount of Microsoft’s total profit, that division more than doubled in profitability from 2010 to 2011.
