From a post at Game Couch about his library's Wii Bowling program:
We ran an hour-long commercial for the Wii.
Or the Wii advertises itself very, very well. By the end of the program, we could have sold Wiis to most of the participants. I actually felt a little skeevy fielding questions about how much the Wii costs, how easy it is to set up, and the like. I assuaged this by ordering copies of Wii for Dummies for the system, but still wonder how many new customers Nintendo gets from programs like this and what, if anything, Nintendo is doing for libraries.
