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
The console was publicly unveiled under the name Xbox One on May 21, 2013 in a press conference designed to cover the unit's broad multimedia and social capabilities. A second press event for the console was held during E3 2013, focusing on its video game-oriented functionality. At that time, Microsoft announced that the console would be released in 21 different markets on November 22, 2013, but this was later amended down to 13. The change, which pushed the release date for the other eight markets to 2014, was attributed to unforeseen complexity in localizing the device's voice recognition capabilities. Later, in September 2014, the Xbox One was released in 26 markets, including remaining markets in Europe, the Japanese market, and Middle Eastern markets.
