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.

The integrated Xbox Live service launched in November 2002 allowed players to play games online with or without a broadband connection. It first competed with Dreamcast's online service but later primarily competed with PlayStation 2's online service. Although these two are free while Xbox Live required a subscription, as well as broadband-only connection which was not completely adopted yet, Xbox Live was a success due to better servers, features such as a buddy list, and milestone titles like "Halo 2" released in November 2004, which is the best-selling Xbox video game and was by far the most popular online game for years.
