Jump Ahead.

The Xbox One is Microsoft's entry into The Eighth Generation of Console Video Games. It was released in North America on November 22, 2013. Its odd name, the "One", represents Microsoft's desire for the system to become an all-in-one living room entertainment system as well as aligning with Microsoft's "One" branding in many of their products. The Xbox One integrates video games with Internet video, music, and live television — a goal Microsoft had wanted to accomplish since the original Xboxnote , and which it had partially realized with the Xbox 360.

This system has considerably more power under the hood than the Xbox 360. Like the competing PlayStation 4, the Xbox One switched from a PowerPC chipset to a x86-64 chipset similar to contemporary PCs to allow for better PC ports. This had the side effect of removing hardware backwards compatibility with the original Xbox and the Xbox 360.note 

Aside from providing better graphics, the improved hardware allows for additional features such as full-fledged multitasking. The console actually runs three separate operating systems simultaneously: the first, referred to as "Xbox OS", revolves around the runtime environment for games; the second, built on the Windows NT kernelnote , handles the Dashboard and any apps that don't require native access to the hardware; the third, a version of Microsoft's Hyper-V virtualization technology, allows the first two to run simultaneously. Games and apps can run side by side using a "snap" view similar to the one seen in Windows 8 — demos show a docked instance Skype or Internet Explorer to the side of the screen while someone plays a game. Microsoft has cited the software architecture as the key to future-proofing the console as it was structured from the get go to be upgradeable with new features and services while not compromising performance.

In 2015, the console was upgraded to a variant of Windows 10note  which brought, among other things, a redesigned dashboard featuring the return of the popup guide, Xbox 360 backwards compatibility via a self-contained emulator, DirectX 12 which improves both top end graphics performance and low end power efficiency, and the new Microsoft Edge web browser to replace IE. Future subsequent updates in 2016 will include Microsoft's digital assistant Cortana (fittingly enough) and support for the Windows universal app platform which will allow apps and lighter weight games to run on the console along with Windows PCs, phones, tablets, and other devices. This will allow for a more open market for indie developers to publish games that don't require the full power of the system in a way more like a mobile app store. Other 2015 updates included a partial backwards-compatibility program for Xbox 360 games (in practice more like downloaded ports of 360 games that can use their disc versions as DRM keys) that included the ability to play the entire Halo and Gears of War series on the same console.

The console also features an HDMI in-port, which allows owners to use the system as a passthrough for a cable or satellite box to watch live TV. Users can seamlessly jump between playing a game and watching TV without having to change inputs — and they can engage in more interactive content with their TV through a custom channel guide, termed OneGuide, and app integration. This has also led to the Inception-style discovery that it is possible to play a PlayStation 4, or any other HDMI-out console, from within an Xbox One.

After the system's big reveal in early 2013, concerns were raised about DRM and the included-with-every-system-by-default Kinect's always-on status. The official word from Microsoft said the system would allow used games, but publishers would have to decide if they wanted to charge a fee for each re-install — and games could only be re-installed so many times before the system negated future installations. Microsoft also said it would need to keep track of what games a user had installed, so the console would have to check in with Microsoft every twenty-four hours (with some content requiring a 1-hour check in). The Kinect would also need to remain plugged into the system at all times, which would allow gamers to issue voice commands to the system and use the Kinect for other purposes (as well as allow Microsoft to mine valuable user data). Along with the $499 price tag, these factors led to increased controversy amongst gamers and the media. On top of those issues, Microsoft had planned to make the console available in a scant twenty-one countries; if you imported a console into a country where you couldn't officially buy it, the DRM would make sure it wouldn't function.

After widespread ridicule from all sides (including a couple of scathing burns from Sony during its E3 2013 presentation), Microsoft eventually reversed its policy on DRM. The system no longer requires daily check-ins, used game fees, or region coding — but only after downloading a patch to disable those "features", which requires an Internet connection when setting the system up for the first time (everyone without Internet access or with slow Internet speeds gets shafted). The backtrack forced Microsoft to drop several features that its original DRM scheme would've enabled, such as loading games installed to the hard drive without the disc inserted and the ability to loan out digital copies of games.note  On August 12, 2013, Microsoft also retracted the "always-plugged-in" requirement for the Kinect. Furthermore, on May 13, 2014, Microsoft announced that it was introducing a Kinect-less SKU for $399, 399, or £349, matching the PlayStation 4, though the Kinect bundle will still be sold at $499.

Originally, a second-generation Kinect came with every Xbox One, but it is now a secondary purchase at $149.99. While the Xbox 360's Kinect relied on basic skeletal tracking, the new version improves on this by using a full 1080p sensor to read more precise details and subtle motions such as wrist rotation, musculature, and even a user's heart rate. It can now recognize six people at once instead of two, all in a smaller areanote , and with virtually no latency. Voice commands have similarly improved and now come nearly universally implemented in the system. The console can even boot up from hibernation by saying "Xbox On".

The Xbox One has deeper integration with Skype, which will take over for the existing chat system and integration with the now-defunct Windows Live Messenger that the 360 featured. An updated version of SmartGlass will be available for smartphones and tablets, which (like Kinect 2.0) will hopefully fulfill its original vision, as it will be natively included with the Xbox One (rather than added-on later as it was on the 360). The use of WiFi Direct will allow it to bypass a router and thus improve its performance. The controller will also use WFD note .

Microsoft later made a more evolved version of its Xbox 360 predecessor with refinements to ergonomics and "impulse triggers" (which contain their own vibration motors for feedback, such as recoil from a gun trigger). Whereas previous generations assigned controllers to virtual "ports", the Xbox One's optional Kinect sensor will identify each individual controller by a built-in infrared LED array. This will allow for, among other things, players to switch out controllers seamlessly and split-screen games to automatically align teams/controllers based on where the players are sitting.

At E3 2016, two new models of the console were announced. The first, the Xbox One S is a simple mid-cycle redesign that is 40% smaller, contains an internal power supply, an IR blasternote , and a slight processor bump to support 4K video playback and upscaling games. The more significant of the two is Project Scorpio to be released in 2017. The best way to describe it is a PC in a console format. It will offer the bleeding edge specs available in a high end gaming PC capable of native 4K and VR, at a comparable price, while still featuring the conveniences of a console such as a living room-centric interface. With Scorpio, Microsoft is looking to break the tradition of console "generations". Using the Windows 10 universal app platform, Xbox One, Scorpio, and PCs will all be able to play the same software at varying levels of performance. People who want a relatively cheap, convenient box to plug into the TV can buy the One S. People who demand bleeding edge performance and are willing to pay for it can buy a PC or Scorpio. Additionally, Microsoft has plans to launch a pair of Windows 10 based streaming devices: a set-top box similar to an Apple TV or Amazon Fire TV, and a "stick" similar to Chromecast or Amazon Fire Stick. These will expand on their philosophy of breaking the traditional console paradigm by not only offering lighter-weight games built on the Windows universal app model, but also support streaming from an Xbox console as is already capable on Windows 10.
