According to Mike from Nintendo’s Marketing Department, the Wii name is apparently a “bad thing for the company’s reputation”. This is what he supposedly said:
We have received over 200,000 e-mails with complaints about the Wii, and the console name has been commonly associated with urine. We have been the target of many jokes, and we strongly believe that it’s a bad thing for the company’s reputation
