"Xbox is fifth most discussed brand online"

[Impulsivity]

you should do Wii instead of just Nintendo. The Wii has more brand recognition in a lot of ways then even Nintendo does at this point.

While Xbox and Microsoft seem somewhat distinct (probably by design) Sony and Playstation and Nintendo and Wii are far more interchangeable. If someone is looking for Microsoft they are most likely looking for tech support or Windows 7 news and not the xbox, but if someone is looking for either Nintendo or Wii its pretty clear what they're interested in.

   notice there the Wii is significantly higher then the Xbox especially around the holiday periods, if you add Nintendo to Wii its pretty staggering how much interest is out there.
