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 (console)
Due to the immense popularity of gaming consoles in Japan, Microsoft delayed the release of the Xbox in Europe to focus on the Japanese video game market. Although delayed, the European release proved to be more successful than the launch of the Xbox in Japan.
