According to the Nintendo Style Guide, the name "is simply Wii, not Nintendo Wii." This means it is the first home console Nintendo has marketed outside of Japan without the company name featured in its trademark. While "Wiis" is a commonly used pluralization of the console, Nintendo has stated that the official plural form is "Wii systems" or "Wii consoles."Nintendo's spelling of "Wii" with two lower-case "i" characters is meant to resemble two people standing side by side, representing players gathering together, as well as to represent the Wii Remote and Nunchuk. The company has given many reasons for this choice of name since the announcement; however, the best known is:
� Wii sounds like 'we', which emphasizes that the console is for everyone. Wii can easily be remembered by people around the world, no matter what language they speak. No confusion. No need to abbreviate. Just Wii.
