While Microsoft’s Xbox brand originally referred to its Xbox video game consoles, it’s since evolved to cover various online gaming services such as Xbox Live and Project xCloud and select video game titles on Windows 10, iOS, and Android devices.

Microsoft’s Xbox One, the third generation of Xbox consoles, launched in late-2013. Strong backwards compatibility support for OG Xbox and Xbox 360 titles was eventually added with 4K and HDR gaming made possible with the release of the Xbox One S and Xbox One X iterations.

During the Xbox One’s lifecycle, Microsoft began releasing a number of Xbox-branded video games on Windows 10 devices in addition to Android and iOS smartphones and tablets. Many of these games, such as Forza Horizon 4, Sea of Thieves, and Ori and the Will of the Wisps, were full console games while others, like Microsoft Solitaire Collection and Gears Pop, were smaller mobile experiences.

The Project xCloud service, which allows for the full streaming of video games over the cloud, and the Xbox Game Pass subscription service also launched during this time.

Late-2020 will see the launch of the Xbox Series X, Microsoft’s fourth generation of Xbox video game consoles.
