My boss bought a Nintendo DS for the sole purpose of playing Brain Age's Sudoku. This is just a perfect example of how Nintendo is broadening their demographics. It also happens to be one of the rare examples of how a company's strategy is actually noticeable. My boss is just the newest of these examples I'm finding in my life.
The first example was last Christmas when I played Nintendo Wii with my 80 year old grandmother. I have to admit she schooled me at bowling. In the past few years Nintendo has made huge advances breaking out of the 13-24 male bracket. I can't even explain why this is interesting to me other than I can point it out when I see it happening.
By the way, have a lucky 7-7-07.
