Rancidlunchmeat brought up demographics, which is why I responded with information about demographics. If you're not going to follow the conversation, don't butt in.
Before you turn on the snark, maybe you should follow the conversation. This is about sales. Part of the whole upset over Wii sales is that maybe they're reaching a new demographic. That's why demographics came up; they're framed from the point of reference of sales. Talking about users does not help one tiny bit, not when your own numbers point out that the owners are the same! I mean, fine. 45% of players are females. Again, what does this mean? Is this more or less than last gen? Out of Wii's very respectable sales, how many are to women? A number with no frame of reference is worse than useless.
Did you know that NPD also tracks software sales? The unprecedented success of Carnival Games, the popularity of Wii Fit, and the demographics of the people who play (and therefore result in sales of) Wii games are quite relevant to publishers, which is why 3rd-party Wii games go for mass appeal based on the user demographic. It's why the Wii shelf is full of puzzle games and mini-games. Demographics matter. I can't think of a single industry that doesn't follow its user demographics, but instead blindly follows raw sales numbers.
Except NPD supposedly discovered who the demographics are! That's where the 18/19% of PS2 owners owning a Wii comes from. The peanut gallery seems to think that the success of Carnival Games, of Wii Fit, the appearance of Wii stuff on Ellen means that the Wii has hit a completely new market. Too bad the peanut gallery seems to thrive on being wrong. They might actually be right, but again, NPD seems to say otherwise. Now, I can't say that the Wii hasn't hit an actual new demographic (there's plenty of anecdotal evidence otherwise regarding moms and grandmas) but how big is it? If NPD is correct, then it's no larger than about 30%.
Do we have evidence that these 'ultra-casual' titles would not have succeeded on the PS2's userbase? That's what I'm guessing at: that if NPD's numbers are right, then maybe this 'new' 'ultra-casual' market isn't new at all. It's always been there, at least since PS2 days, just very few people actually targeted it specifically. That's the dirty secret; that the 'core' audience from previous generations has always been an extremely vocal minority -- it's not a phenomenon new to this generation.
But if you have insight into NPD's data regarding console ownership, please share it. The idea that the Wii hit a new demographic was more palatable to me as well, but I'm in no position to question actual numbers.
