The Nintendo Switch is a video game console developed by Nintendo and released worldwide in most regions on March 3, 2017. Released in the middle of the eighth generation of home consoles, the Switch succeeded the Wii U and competed with Sony's PlayStation 4 and Microsoft's Xbox One; it also competes with the ninth generation consoles, the PlayStation 5 and Xbox Series X/S.
The Switch is a tablet that can either be docked for home console use or used as a portable device, making it a hybrid console. Its wireless Joy-Con controllers function as two halves of a standard controller and alternatively as individual controllers, featuring buttons, directional analog sticks for user input, motion sensing, and tactile feedback. A pair can attach to the sides of the console for handheld-style play, attach to a grip accessory to provide the form of a separated gamepad, or be used unattached. The Switch's system software supports online gaming through internet connectivity, as well as local wireless ad hoc connectivity with other consoles. Switch games and software are available on both physical flash-based ROM cartridges and digital distribution via Nintendo eShop; the system has no region lockout. Two hardware revisions were released: the handheld-only Switch Lite, released on September 20, 2019; and a higher-end version featuring an OLED screen, released on October 8, 2021.
