Xbox One is a video game console developed and marketed by Microsoft. Announced on May 21, 2013, it is the successor to the Xbox 360 and is the third console in the Xbox family. It directly competes with Sony's PlayStation 4 and Nintendo's Wii U as part of the eighth generation of video game consoles. Xbox One was released across North America, several European markets, Australia, and New Zealand on November 22, 2013, and is scheduled for release in 26 other markets, including Japan, the remaining European markets, and the Middle East, sometime in September 2014. Microsoft and various publications have classified the device as an "all-in-one entertainment system", making it a competitor to other home media devices such as the Apple TV and the Google TV platforms.

Moving away from the Xbox 360's PowerPC-based architecture and back into the x86 architecture used in the first Xbox, the console features an AMD processor built around the x86-64 instruction set. Xbox One places an increased emphasis on entertainment integration, offering the ability to overlay live television programming from an existing set-top box, split-screen multitasking of applications, and improved second screen support. The console includes a newly upgraded Kinect motion sensing peripheral, previously an optional attachment for the Xbox 360. Microsoft is emphasizing the Kinect's integration with Xbox One through features such as a built-in Skype client for videoconferencing, user recognition and tracking, and the ability to use voice commands and gestures to navigate the console's user interface. New gaming functionality includes an expanded Xbox Live service, improved Kinect functionality, cloud computing, the ability to automatically record and share video highlights from gameplay, and support for live streaming gameplay online.

Upon its unveiling, Xbox One was criticized for its initial digital rights management policies (including a requirement for a periodic connection to the internet, and ambiguous restrictions on the resale and sharing of previously-purchased games), along with Kinect usage requirements and higher price than its competitors. In response to the criticism, Microsoft dropped these restrictions prior to releasing the console.

History

Xbox One at E3 2013

Xbox One is the successor to Xbox 360, Microsoft's previous video game console, which was introduced in 2005 as part of the seventh generation of video game consoles. As of June 2013, it remains in production by Microsoft, having received a number of small hardware revisions to reduce the unit's size and improve its reliability. In 2010, Microsoft's Chris Lewis stated that the 360 was about "halfway" through its lifecycle; this was aided by the introduction of the Kinect device that year which Lewis stated would extend the lifecycle by five years.

Initial hardware for the 360's successor, commonly referred to by the industry as the "Xbox 720", was reportedly in hands of developers as early as May 2011. The official developer kit was codenamed Durango, and appeared to be available to developers by mid-2012. Leaked documents suggested that the new console would include an improved Kinect device, cloud access to games and media, integration with phone and tablet devices, and technology to provide players heads-up displays on glasses worn by the player, codenamed "Fortaleza"; Microsoft did not comment on these reported features. Similar, leaked design documents also suggested that Microsoft was seeking to eliminate the ability to play used games, though Microsoft later clarified they were still reviewing the design and were "thinking about what is next and how we can push the boundaries of technology like we did with Kinect", but did not comment on the validity of the information.

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 on June 10, 2013, focusing on its video game-oriented functionality. At that time, Microsoft announced that the console would release in 21 different markets at launch, but this was later amended down to 13. The change, which pushed the release date for the other 8 markets to 2014, was attributed to unforeseen complexity in localizing the new Kinect peripheral.

Hardware

Xbox One's exterior casing consists of a two-tone "liquid black" finish; with half finished in a matte grey, and the other in a glossier black. The design was intended to evoke a more entertainment-oriented and simplified look than previous iterations of the console; among other changes, the LED rings used by Xbox 360 are replaced by a glowing white Xbox logo used to communicate the system's status to the user.

It is powered by an AMD "Jaguar" Accelerated Processing Unit (APU) with two quad-core modules totaling eight x86-64 cores clocked at 1.75 GHz, and 8 GB of DDR3 RAM with a memory bandwidth of 68.3 GB/s. The memory subsystem also features an additional 32 MB of "embedded static" RAM, or ESRAM, with a memory bandwidth of 109 GB/s. Eurogamer has been told that for simultaneous read and write operations the ESRAM is capable of a theoretical memory bandwidth of 192 GB/s and that a memory bandwidth of 133 GB/s has been achieved with operations that involved alpha transparency blending. The system includes a 500 GB non-replaceable hard drive, and a Blu-ray Disc optical drive. About 362 GB of hard drive space is available for the storage of games; support for external drives will be added in a future update, scheduled to come in April 2014.

It was reported that 3 GB of RAM would be reserved for the operating system and utility software, leaving 5 GB for games. The graphics processing unit (GPU) is based on an AMD GCN architecture with 12 compute units, which have a total of 768 cores, running at 853 MHz providing an estimated peak theoretical power of 1.31 TFLOPS. For networking, Xbox One supports Gigabit Ethernet, 802.11n wireless, and Wi-Fi Direct.

"We purposefully did not target the highest end graphics. We targeted it more as a broad entertainment play. And did it in an intelligent way."

—Greg Williams, GM of Xbox silicon development

Xbox One supports 4K resolution (3840×2160) (2160p) video output and 7.1 surround sound. Yusuf Mehdi, corporate vice president of marketing and strategy for Microsoft, has stated that there is no hardware restriction that would prevent games from running at 4K resolution. Unlike the Xbox 360, the Xbox One does not support 1080i and other interlaced resolutions. Xbox One supports HDMI 1.4 for both input and output, and does not support composite or component video.

The console can monitor its internal temperature and adjust accordingly to prevent overheating; alongside increasing fan speed, additional measures can be taken, including forcing the hardware to run in a lower power state—a feature that was not present on Xbox 360. Restricting power consumption lowers maximum performance, but the setting would be intended as a last resort to prevent permanent hardware damage.

Controller

Xbox One's controller maintains the overall layout found in the Xbox 360's design. The directional pad has been changed to a four-way design, and the battery compartment is slimmer. Menu and View buttons have replaced the Start and Back buttons. Each trigger features independent rumble motors called "Impulse Triggers", which allows developers to program directional vibration. One trigger can be made to vibrate when firing a gun, or both can work together to create feedback that indicates the direction of an incoming hit. Consumers who Pre-ordered the Xbox One, "Day One Edition" included controllers that had the words "Day One 2013" engraved in the center of the controller. Microsoft invested over $100 million into refining the controller design for the Xbox One.

Kinect

Further information: Kinect for Xbox One

Xbox One ships with an updated version of Kinect for motion tracking and voice recognition; the new Kinect uses a 1080p wide-angle time-of-flight camera (in comparison to the VGA resolution of the previous version), and processes 2 gigabits of data per second to read its environment. The new Kinect has greater accuracy over its predecessor, can track up to 6 skeletons at once, perform heart rate tracking, track gestures performed with an Xbox One controller, and scan QR codes to redeem Xbox Live gift cards. The Kinect microphone remains active at all times by default so it can receive voice commands from the user when needed, even when the console is in sleep mode (so it can be awakened with a command).

As was the case on the Xbox 360, Kinect usage is optional, and privacy settings are available for adjusting how the sensor operates.

A Windows-compatible version of the new Kinect is scheduled to be released in Summer 2014.

Software and services

Media inter-connectivity

Similarly to Windows 8, Xbox One can snap applications (such as music, video, Skype, and Internet Explorer) to the side of the screen as a form of multitasking. Xbox One can also serve as a pass-through for an existing television set-top box over HDMI. This functionality allows users to watch live TV from their existing provider through the console, and access features such as show recommendations, an electronic program guide (branded as OneGuide), and voice commands. The set-top box is controlled by the console by either using an IR blaster in the Kinect sensor, or the HDMI-CEC protocol. On launch, OneGuide is only compatible with television providers in the United States.

Voice control

The console features a similar, albeit richer set of voice control abilities than those found in the first generation Kinect, allowing the user to control Xbox functions via voice command. Users can also initiate conversations through Skype.

Operating system

The device reportedly runs three operating systems: Xbox OS, an OS based on the Windows kernel, and another OS that allows the other two operating systems to communicate by virtualisation (as a hypervisor). This integration allows features like snapped Skype calls while in game.

The Windows kernel on the Xbox is not compatible with standard Windows programs, though developers will be able to port them over with little effort.

Xbox Live

Main article: Xbox Live

Microsoft have stated that the Xbox Live service has been scaled up to use 300,000 servers for Xbox One users, but have not stated how many of the servers are physical and how many are virtual. Cloud storage is available to save music, films, games and saved content and developers are able to use Live servers (along with the Windows Azure cloud computing platform) to offer dynamic changes to players within their game. The service is still be subscription-based. The friends list has been expanded to 1,000 friends.

SmartGlass

Xbox SmartGlass provides extended functionality on Xbox One, allowing devices running Windows Phone, Windows 8, iOS and Android to be used as a "second screen." A demo during the E3 press conference demonstrated its use for setting up a multiplayer match in another game in the background on a tablet while playing another game on the television.

Recording and streaming

Xbox Live Gold subscribers can use the Upload Studio app to edit and share clips from the last five minutes of gameplay footage that is automatically recorded by the console. Integration with the live streaming platform Twitch will be provided in 2014; users will be able to use voice commands to immediately begin streaming footage of their current game directly to the service, and use the Kinect microphone for commentary and voiceovers. Despite the ability to record gameplay, Xbox One does not include DVR functionality for recording television programs; executive Yusuf Mehdi indicated that Xbox One would "work in tandem" with existing TV providers, but that Microsoft may need to work with them directly to provide extended functionality such as DVR integration.

Games

Microsoft presented several first-party and third-party titles for Xbox One at its E3 2013 news conference, some of which are exclusive to the console. First-party titles unveiled for Xbox One include Forza Motorsport 5, Ryse: Son of Rome, a revival of Killer Instinct, Project Spark and a teaser for an upcoming Halo game.

"Absolutely; you can certainly plug an Xbox 360 in the back – that was one of my first questions when I heard about the [HDMI-in] feature,"

—Larry Hryb, Xbox Live Director of programming

Xbox One games are distributed on Blu-ray Disc and as downloads through Xbox Games Store. All Xbox One games, whether purchased as downloads or discs, must be cached on the console's hard drive. In the case of disc-based games, the disc will still be required to play. However, if the game is installed on another console, and that console owner no longer has access to the disc, the owner has the option of unlocking the install on their hard drive by purchasing it through Xbox Live; the installed game then acts as a game installed on the hard drive. Single-player games that take advantage of cloud computing require an internet connection.

Xbox One does not have native backward compatibility with original Xbox or Xbox 360 games. Xbox Live director of programming Larry "Major Nelson" Hryb did state that users could theoretically use the HDMI-in port on the console to pass an Xbox 360 through Xbox One. In an interview, Senior director Albert Penello revealed the possibility that Microsoft could offer backwards compatibility with older titles through a cloud gaming system in the future.

Reception

Pre-release

After the official reveal in May 2013, the editorial staff of Game Informer offered both praise and criticism for the console. Matt Helgeson described the console as Microsoft's intent to "control the living room". He called Xbox One's instant switching features "impressive", and that the console was "a step in the right direction" with regards to TV entertainment, especially the prospect of avoiding the usage of non-intuitive user interfaces often found on cable set-top boxes. Jeff Cork said that Microsoft had "some great ideas" for the console, but that it failed to properly communicate them. There were also concerns surrounding the console's DRM system; Microsoft touted that all Xbox One games could be played either locally, or through an online game library on any other Xbox One, and that a user's library could also be shared with up to ten designated "family" members (each game could only be played by one remote player at a time). Users would have been able to trade in games at "participating retailers" at no extra charge, and could also transfer a game directly to any Xbox Live friend on their list for at least 30 days, but only once. However, this system required all games, regardless of whether they were purchased on disc or digitally, to be tied to the user's Xbox Live account and console. Additionally, the console was to connect to the internet to synchronize the user's library once every 24 hours; if the console was not connected to the internet at this time, access to all games would be disabled until the console was connected again.

Industry and consumer reaction to Microsoft's DRM plans were largely negative. Gaming and PC websites expressed concern over possible restrictions on the resale of used games, the requirement of online authentication every 24 hours for offline games as well as concern among independent video game retailers. Microsoft clarified the situation, stating that it would be up to the game developers to decide if used games could be played and if there would be any activation fees. Xbox Chief Marketing and Strategy Officer Yusuf Mehdi defended the system by arguing that it was primarily designed around digital distribution, but that Microsoft felt that dropping physical media entirely would not have been the "best thing" for consumers. He also noted that the company was not "giving in" to publishers' objections to used games, but rather trying to balance the needs of consumers and the industry, and that the the trading and sharing abilities abilities of the platform added a level of flexibility not seen on other digital distribution platforms at the time.

Following Microsoft's E3 press conference on June 10, 2013, perceptions of Xbox One by critics changed. Multiple GameSpot writers were critical of the new console; Mark Walton considered Xbox One's launch lineup as portrayed by the conference to be "uninspired", "lackluster" and plagued by "old men in suits, a stream of buzzwords, and superficial games that valued visuals over innovation" (as opposed to the "new generation of gaming" that Microsoft had promised to present during the event, by contrast to its previous television-oriented presentation) alongside strict digital rights management (DRM) practices, while editor Tom McShea noted that despite the increased capabilities and cloud-oriented nature of Xbox One, the presentation consisted only of "pretty games that didn't offer any noticeable change to the core experience we've already been playing [on the Xbox 360]", providing existing owners with little reason for spending $499 on the new console. Journalists and consumers jokingly named the console the "Xbone", believing that Microsoft's decisions for the systems were in poor judgement. After Sony's E3 press conference later that evening, McShea went on to say that Microsoft had become anti-consumerist, trying to "punish their loyal customers" with strict restrictions, and that "by saying no to the used game restrictions and always-online that Microsoft is so happily implementing on the Xbox One, Sony has elevated the PlayStation 4 as the console to grab this holiday season." Rafi Mohammed, author of "The Art of Pricing" felt that Microsoft priced Xbox One "too high", and the $100 premium over its competitor could "derail" the system during the 2013 holiday season.

On June 19, 2013, following E3, Microsoft ultimately announced that it would reverse its DRM and game licensing changes for Xbox One so that users could "play, share, lend, and resell [their] games exactly as you do today on Xbox 360." As a result, the disc authentication and internet connection requirements were dropped—however the planned family sharing and disc-free play features were dropped as a result. The console would still require an internet connection to download and install a system software update to enable these changes, but the console would now be otherwise usable without a permanent internet connection. Xbox One chief product officer Marc Whitten stated that the family sharing feature may return in the future, but could not be implemented on launch due to time restraints. In his statement on the new policies, Don Mattrick, the then president of Microsoft's Interactive Entertainment Business, said that the company took notice of the negative public opinion, and he thanked the public for giving their feedback "to reshape the future of Xbox One". Other analysts believed that the change was in direct response of Sony's aggressive position during the E3 conference. Mattrick, who had been a leader in Xbox One development, announced his departure from Microsoft on July 1, 2013, to become CEO of Zynga. Analysts speculated that his departure was predicated on the poor response and subsequent reversal of the plans for Xbox One.

Similar concerns were faced by an initial requirement for the Kinect sensor to be plugged into Xbox One at all times. Privacy advocates contended that the increased amount of data which could be collected with the new Kinect (such as a person's eye movements, heart rate, and mood) could be used for targeted advertising. Reports also surfaced regarding recent Microsoft patents involving Kinect, such as a DRM system based on detecting the number of viewers in a room, and tracking viewing habits by awarding achievements for watching television programs and advertising. While Microsoft's privacy policy prohibits the use of Kinect data for advertising, critics did not rule out the possibility that these policies could be changed. Concerns were also raised that the device could also record conversations, as its microphone remains active at all times. In response to the criticism, a Microsoft spokesperson stated that users would be provided with privacy information and options to disable or "pause" Kinect, and that user-generated content such as photos and videos would not leave the console without explicit user permission. Similarly to its DRM changes, Microsoft also reversed the mandatory Kinect requirement, but the console still shipped with Kinect on launch day.

Sales

On November 22, 2013, Microsoft confirmed that it had sold one million Xbox One consoles within its first 24 hours of being available. Based on approximately 102,000 shopping receipts tracked by InfoScout, 1,500 of which included a purchase of either a video game or a video game console, the Xbox One was the highest-selling console during the Black Friday sales period in the United States.

On December 11, 2013, Microsoft announced that it had sold approximately 2 million units in its first 18 days on sale. On December 12, 2013, Microsoft announced it was the fastest selling console in the United States based on NPD Group figures, however the NPD report clarified, "PlayStation 4 sales included an additional week within the November data month compared to Xbox One. When looking at sales on an average per-week basis, Xbox One led PS4. Keep in mind, however, that supply typically becomes constrained in the second week after launch."

On January 6, 2014, Microsoft announced that approximately 3 million consoles had been sold worldwide in 2013. In their Q2 2014 earnings report on January 23, 2014, Microsoft announced that 3.9 million Xbox One units had been shipped worldwide.
