The Wii (pronounced as the English pronoun we, ) is the fifth home video game console released by Nintendo. The console is the direct successor to the Nintendo GameCube. Nintendo states that its console targets a broader demographic than that of Microsoft's Xbox 360 and Sony's PlayStation 3, but it competes with both as part of the seventh generation of video game systems.

A distinguishing feature of the console is its wireless controller, the Wii Remote , which can be used as a handheld pointing device and can detect acceleration in three dimensions. Another is WiiConnect24, which enables it to receive messages and updates over the Internet while in standby mode. 2006/speech/english.html" target="_blank">Nintendo Corporation - Nintendo President, Satoru Iwata, media briefing speech at E3 2006
