Windows Phone - a mobile operating system developed by Microsoft, was released on October 11, 2010.
On October 21, deliveries of the first devices started on the basis of the new platform.
The operating system is the successor to Windows Mobile, although incompatible with it, with a completely new interface and - for the first time - with the integration of Microsoft services: Xbox Live gaming and the Zune media player.
Unlike the previous system, Windows Phone is more focused on the consumer market than on the corporate sphere.
The new operating system Windows 10 for mobile devices is called "Windows 10 Mobile", instead of Windows Phone 10.
