Microsoft Profit by Products

A very useful chart from [Business Insider](http://www.businessinsider.com/chart-of-the-day-microsoft-operating-income-by-division-2010-2?utm_source=Triggermail&utm_medium=email&utm_campaign=SAI_COTD_021010). They just track Microsoft profit by division (business unit) and put the number on the chart. Good visualization. For a better illustration, I put another layer on this graph: Microsoft products launch date. You can clearly see the immediate profit rising in Windows/Office division after Vista/Office 2007 launch in Jan 2007 and then again in Oct 2009 after Windows 7 general availability. Online Services division had a biggest loss in Jun 2009, probably due to big marketing budget of Bing relaunch. I can't find why Entertainment and Devices went down in Jun 2007, maybe just only operation loss.
