Xbox
Released in 2001, the Xbox control pad was the first controller made for the original Xbox. The Xbox controller features two analog sticks, a pressure-sensitive directional pad, two analog triggers, a Back button, a Start button, two accessory slots and six 8-bit analog action buttons (A/Green, B/Red, X/Blue, Y/Yellow, and Black and White buttons). The standard Xbox controller (originally nicknamed the "Fatty" and later the "Duke") was originally the controller bundled with Xbox systems for all territories except Japan.
Xbox One system software
During the Electronic Entertainment Expo 2015 in June, Microsoft discussed three major features that later came to Xbox One consoles in November 2015: Windows 10 streaming, Xbox 360 backward compatibility, and an interface redesign known as the New Xbox One Experience. In advance of the public release of Windows 10, a July 2015 update let users stream games from their Xbox One to any device running Windows 10, a feature announced in January 2015. The service streams only to one device at a time.
