The Wii U (/ˌwiː ˈjuː/ WEE YOO) is a home video game console developed by Nintendo as the successor to the Wii. Released in late 2012, it is the first eighth-generation video game console and competed with Microsoft's Xbox One and Sony's PlayStation 4. The Wii U is the first Nintendo console to support HD graphics. The system's primary controller is the Wii U GamePad, which features an embedded touchscreen, directional buttons, analog sticks, and action buttons. The screen can be used either as a supplement to the main display or in supported games to play the game directly on the GamePad. The Wii U Pro Controller can be used in its place as a more traditional alternative. The Wii U is backward compatible with all Wii software and accessories. Games can support any combination of the GamePad, Wii Remote, Nunchuk, Balance Board, or Nintendo's Classic Controller or Wii U Pro Controller. Online functionality centers around the Nintendo Network platform and Miiverse, an integrated social networking service which allowed users to share content in game-specific communities. Response to the Wii U was mixed. It was praised for its innovative GamePad controller, improvements to online functionality over the Wii, backwards compatibility with Wii software and peripherals, and price. However, it was criticized for its user interface and functionality, and the GamePad's short battery life. It had low sales, primarily credited to a weak lineup of launch games, limited third-party support, and poor marketing including the lack of distinguishing the unique functionality of the GamePad from just being a tablet device for the Wii. Production of the Wii U ended on January 31, 2017. On March 3, 2017, Nintendo released its successor, the Nintendo Switch, which retained and refined concepts introduced with the Wii U.
