Microsoft never mentions any financial stats about its Windows Phone platform at any of its earnings report. Entertainment and Devices Division at Microsoft holds the Windows Phone platform under Microsoft’s management tree. Seekingalpha has tried to unearth Windows Phone division’s revenue numbers by subtracting Xbox, Skype and Media Room revenues from EDD’s whole revenue.
The above image is the final chart they came up with which shows Windows Phone made $736 approx in FY2012. I doubt that the number will be less than this. What do you think? Also which division at Microsoft will get the patent royalties collected from other companies?
