You seem to be ignoring the other aspects of the market because it proves your argument wrong, I ntoice you are skirting the PC gaming market entirely, no it is not the same as bringing in VHS and DVDs since they are not gaming systems the PC is a gaming machine, notice how the 80's and early 90's were the height of PC gaming, how convenient for you to ignore them, and notice how it was in direct competition at the time of the NES and was stronger and more technologically advanced than the NES, intersting that the Wii is in the same posiition
The only reason I ignored the competitors to the NES and PS1 initially was to keep the argument from getting too cluttered and I did expalin why they were irrelevant to the discussion because multiple console ownership and the PC gaming market, which was competitors to the NES, much like the N64 and Sega saturn were to the PS, all you've given is saying that the market expaned, but have failed to even acknowledge the influence of PC gaming, and the arcades durng the NES and SNES eras, you seem unwilling to accept that the whole PS expanding the market is little more than clever marketing originated by Sega (the whole nintendont ads) and perfected by Sony to make it seem like they were catrering to a new more adult market when in fact it was merely a migration from the PC gaming which was in decline by the time of the PS.
At the end of the day PS only outsold the NES by a very small marging in every market save the PAL regions due to Nintendo not pushing into the PAL regions earlier, both had competiotn and yet were able to sell well in spite of that, but don't mistake it for being an expanded market.
Also you want data ok,
The C64 (Commodore 64 )Sold 30 million units in its lifetime and had a wealth of gaming software, if you don't think that was a competitor to the NES then you are really just avoiding the facts, it was a gaming PC first and foremost (30 million is a pretty large number of units about the same as the N64 sales...hmmmm)
Predictions:Sales of Wii Fit will surpass the combined sales of the Grand Theft Auto franchiseLifetime sales of Wii will surpass the combined sales of the entire Playstation family of consoles by 12/31/2015 Wii hardware sales will surpass the total hardware sales of the PS2 by 12/31/2010 Wii will have 50% marketshare or more by the end of 2008 (I was wrong!! It was a little over 48% only)Wii will surpass 45 Million in lifetime sales by the end of 2008 (I was wrong!! Nintendo Financials showed it fell slightly short of 45 million shipped by end of 2008)Wii will surpass 80 Million in lifetime sales by the end of 2009 (I was wrong!! Wii didn't even get to 70 Million)
