Definition
The word Wii does not have an official meaning in any language. It is a symbolic name invented by Nintendo in order to express a certain vision the company had for its upcoming gaming system.
Inclusiveness
According to a Flash video posted on the system's website in April 2006 and later quoted on Gamespot.com, one of the reasons behind redubbing the console Wii (pronounced "we") was that the name suggested inclusiveness: "Wii will break down that wall that separates game players from everybody else. Wii will put people more in touch with their games...and each other."
Ease of Pronunciation
Likewise, the name Revolution would be too difficult for consumers in some cultures to pronounce, the video explained: "Wii can easily be remembered by people around the world, no matter what language they speak. No confusion. No need to abbreviate."
Spelling
The unique spelling of the name was also intentional, according to the promotional video, as the use of double-I's was meant to represent both the unique remote controllers that the system uses and convey the image of people gathering to play together. Gamespot.com also noted that "ii" means "good" in Japanese.
Initial Reaction
The reaction to the name change was somewhat negative among gamers and analysts at the time, with the BBC noting that the toilet humor that could be associated with the new moniker and Shacknews.com editor Chris Remo telling CNNMoney.com that Wii was the "worst console name ever."
