Taken from Gaf, cause I'm lazy:
Microsoft recently announced a shake up in the company. Today they confirmed their reporting is changing.
They will change the reporting of their financial results to reflect the company’s strategy and ambitions to build best-in-class platforms and productivity services for a mobile-first, cloud-first world. Beginning in fiscal year 2016, the company will report revenue and operating income based on three operating segments:
Productivity and Business Processes
The Productivity and Business Processes segment includes results from Office and Office 365 for commercial and consumer customers, as well as Dynamics and Dynamics CRM Online.
Intelligent Cloud
The Intelligent Cloud segment includes results from public, private and hybrid server products and services such as Windows Server, SQL Server, System Center, Azure, and Enterprise Services.
More Personal Computing
The More Personal Computing segment includes results from licensing of the Windows operating system, devices such as Surface and phones, gaming including Xbox consoles, and search.
What this means is that Xbox has gone from it's own division over a decade ago to now being lumped into the same segment as Windows. That really shows how Microsoft has changed as a company to focus on Cloud and Office.
Just FYI, this doesn't change much in regards to Xbox. Just makes it incredibly harder to see how the Xbox business is doing on its own but that's nothing new.

(This is my opinion) So, yay they finally give OI on a segment basis, but booh Xbox success will be even more unreadable thanks to being put together with freaking Windows licensing.
