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 (also nicknamed the "Fatty" and later, the "Duke") was originally the controller bundled with Xbox systems for all territories except Japan.
The controller has been criticized for being bulky compared to other video game controllers; it was awarded "Blunder of the Year" by Game Informer in 2001, a Guinness World Record for the biggest controller in Guinness World Records Gamer's Edition 2008, and was ranked the second-worst video game controller ever by IGN editor Craig Harris.

The "Controller S" (codenamed "Akebono"), a smaller, lighter Xbox controller, was originally the standard Xbox controller only in Japan, designed for users with smaller hands.
The "Controller S" was later released in other territories by popular demand and by 2002 replaced the standard controller in the Xbox's retail package, with the larger original controller remaining available as an accessory.
