First generation: Xbox The original
Xbox was released in North America on November 15, 2001, in Japan on February 22, 2002, and in Australia and Europe on March 14, 2002, marking Microsoft's debut in the gaming console market. As part of the
sixth generation of video game consoles, the Xbox competed with Sony's
PlayStation 2, Sega's
Dreamcast (which stopped American sales before the Xbox went on sale), and Nintendo's
GameCube. Built around a 733 MHz 32-bit Intel Pentium III CPU and a 233 MHz Nvidia GeForce 3-based NV2A GPU with 64 MB of memory, the Xbox was the first console offered by an American company after the
Atari Jaguar stopped sales in 1996. Its name was derived from a contraction of
DirectX Box, a reference to Microsoft's graphics
API,
DirectX. The integrated
Xbox Live service launched in November 2002 allowed players to
play games online with a broadband connection. It first competed with
Dreamcast's online service but later primarily competed with
PlayStation 2's online service. Although the two competing services were 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 it having better
servers, features such as a
buddy list, and milestone titles such as
Halo 2 (released in November 2004), which became the best-selling Xbox video game and was by far the most popular online game for the original Xbox system.
Second generation: Xbox 360 The
Xbox 360 was released as the successor of the original Xbox in November 2005, competing with
Sony's
PlayStation 3 and
Nintendo's
Wii as part of the
seventh generation of video game consoles. It featured a custom triple-core 64-bit
PowerPC-based processor design by
IBM with 512 MB of RAM memory. As of June 2014, 84 million Xbox 360 consoles have been sold worldwide. Several retail configurations of the core Xbox 360 model were offered over its lifetime, varying the amount of RAM and internal storage offered. The Xbox 360 showed an expanded Xbox Live service (which now included a limited "Free" tier called Silver), the ability to stream multimedia content from PCs, while later updates added the ability to purchase and stream music, television programs, and films through the
Xbox Music and
Xbox Video services, along with access to third-party content services through
third-party media streaming applications. Microsoft also released
Kinect, a motion control system for the Xbox 360 which uses an advanced sensor system. Two major revisions of the Xbox 360 were released following the initial launch. The Xbox 360 S (typically considered as "Slim"), launched in 2010, featured the same core hardware but with a redesigned, slimmer form factor with a smaller-sized 250 GB hard drive. It also added integrated
802.11 b/g/n Wi-Fi,
TOSLINK S/PDIF optical audio output, five
USB 2.0 ports (compared to the three from older versions) and a special port designed for the Kinect peripheral. The Xbox 360 S replaced the base Xbox 360 unit, which was discontinued, and sold at the same price. A cheaper Xbox 360 S unit, removing the 250 GB drive while adding 4 GB of internal storage, was released later in 2010; the unit allowed users to hook up an external storage solution or purchase a 250 GB internal add-on. The second major revision of the Xbox 360 was the Xbox 360 E, released in 2013. It featured a case style similar to the upcoming
Xbox One, and eliminated one USB port and the S/PDIF, YPbPr component and S-video connections, but otherwise shared the same specifications as the Xbox 360 S.
Third generation: Xbox One The
Xbox One was released on November 22, 2013, in North America, as the successor to the Xbox 360. The Xbox One competed with Sony's
PlayStation 4 and Nintendo's
Wii U and
Switch as part of the
eighth generation of video game consoles. It features an
AMD Accelerated Processing Unit (APU) built around the 64-bit
x86-64 instruction set and can come with up to 12 GB of memory. Announced on May 21, 2013, the Xbox One has an emphasis on internet-based features, including the ability to record and stream gameplay, and the ability to integrate with a
set-top box to watch cable or satellite TV through the console with an enhanced guide interface and Kinect-based
voice control. Following its unveiling, the Xbox One proved controversial for its original
digital rights management and privacy practices; while Microsoft touted the ability for users to access their library of games (regardless of whether they were purchased physically or digitally) on any Xbox One console without needing their discs, and the ability to share their entire library with 10 designated "family" members, all games would have to be tied to the user's Xbox Live account and their Xbox One console, and the console would be required to connect to the Internet on a periodic basis (at least once every 24 hours) to synchronize the library, or else the console would be unable to play any games at all. After an overwhelmingly negative response from critics and consumers (who also showed concerns that the system could prevent or hinder the resale of
used games), Microsoft announced that these restrictions would be dropped. Microsoft was also criticized for requiring the Xbox One to have its updated
Kinect peripheral plugged in to function, which critics and privacy advocates believed could be used as a surveillance device. As a gesture toward showing a commitment to user privacy, Microsoft decided to allow the console to function without Kinect. On June 13, 2016, Microsoft announced the Xbox One S at
E3 2016, which featured a smaller form factor, as well as support for
4K video (including streaming and
Ultra HD Blu-ray) and
HDR. At
E3 2017, Microsoft unveiled
Xbox One X, a high-end model with improved hardware designed to facilitate the playing of games at 4K resolution. In November 2014, Microsoft stated it would not release sales numbers for the Xbox One line. Xbox head Phil Spencer said that while they do internally track sales figures, they do not want their developers to be focused on these numbers as to affect their products, and thus have opted not to report further sales of Xbox hardware going forward. In July 2023, Microsoft revealed that the Xbox One line sold over 58 million units. includes the
Xbox Series X and
Xbox Series S that launched on November 10, 2020. Both are considered members of the
ninth generation of video game consoles alongside the
PlayStation 5, also released that month. Like the Xbox One, the consoles use an AMD 64-bit x86-64 CPU and GPU with up to 16 GB of memory. The Xbox Series X and Series S are high-end and low-end versions comparable to the Xbox One X and Xbox One S models, respectively, with all games designed for this model family playable on both systems. The Xbox Series X is estimated to be four times as powerful as Xbox One X, with support for
8K resolution and up to 120 frames-per-second rendering, with a nominal target of
4K resolution at 60 frames per second. The Xbox Series S is a digital-only unit with less graphic processing power, but can still render at a nominal
1440p resolution at 60 frames per second with support for 4K upscaling. Both consoles features support for new graphics rendering systems including real-time
ray-tracing, and the new Xbox Velocity Architecture that works with the internal SSD drive to maximize the rate of texture streaming to the graphics processor, among other features. Besides games for this new console family, both consoles are fully compatible with all Xbox One games and most hardware, as well as all backward compatible games that were playable on the Xbox One from the Xbox 360 and original Xbox console. To help transition consumers, Microsoft introduced its Smart Delivery system which most of its first-party games and several third-party games would use to offer free updates to Xbox One versions of games to the Xbox Series X/S version over the first few years of the consoles' launch.
Fifth generation: Project Helix Microsoft’s fifth generation of Xbox hardware is tied to a broader strategy of treating “Xbox” as a gaming platform and brand beyond just physical consoles. In 2019, Microsoft Studios was renamed Xbox Game Studios, reflecting a shift in focus toward games, subscriptions and services rather than solely hardware sales. Phil Spencer said in June 2019 that Xbox’s success was measured by how many players played its games and services, not by unit sales. In February 2020, Spencer said Microsoft did not view traditional console manufacturers as its main competitors, but instead saw cloud computing providers as critical competitors, with Microsoft Azure powering Xbox Cloud Gaming and related services. In February 2024, Phil Spencer reiterated Microsoft’s commitment to Xbox console hardware, stating that first-party games would continue to launch “first and foremost” on Xbox platforms and that Microsoft planned to publicly discuss its next generation of hardware later in 2024. In June 2025, Microsoft announced a strategic partnership with AMD to co-engineer silicon for the next generation of Xbox hardware across a range of devices, including future consoles and cloud infrastructure. Amid industry speculation about Microsoft’s long-term hardware plans, Xbox president Sarah Bond confirmed that development had begun on the next Xbox console. As of 2026, Microsoft has not announced a release date for its next-generation Xbox hardware; Phil Spencer has stated that the timing remains undecided, and earlier leaked FTC documents had indicated a 2028 timeframe, which Microsoft later described as based on outdated plans, although reporting citing AMD CEO Lisa Su has suggested that a 2027 launch is possible. The codename for the next Xbox, Project Helix, was announced in March 2026. The console is expected to support both Xbox and Windows games, with more information planned at the Game Developers Conference.

Other devices At the June 2025 Xbox Showcase, Microsoft revealed the Asus ROG Xbox Ally and ROG Xbox Ally X handheld devices, which run Windows and support Xbox games alongside other PC storefronts, planned for release by the end of 2025. The Verge reported that Microsoft previously explored an internally developed handheld before focusing on the ROG Ally partnership. == Games ==
