That's interesting, and great to know, but are they accurate? I mean, I thought sales were a bit higher than that in the US.
I believe they are accurate, they may even be too high.
What I've learned about how sales were "reported" in the olden days suggests we have overblown numbers on really everything.
Methods reported back then were the shipped out of factories or just manufactored units.
When "sold" figures were released they were actually sold TO RETAILERS not customers, as Nintendo would do.
Nintendo did this until 2000. Sony until about 2006. So most figures from prior are overblown.
[You'll notice how Famitsu tracking suddenly got accurate around 2001 as it pertains to NIntendo's figures...hmm.]
For example in my research we have the SNES "shipping" 23.35m to North America (or maybe just Americas), but actually sold within the US to customers was more like 17m... maybe a tad more like 17.2m. That equals 74% of what was reported not the expected 87% (including Canada's 10-13%, and I guess Mexico). You can apply this to all of NCL's consoles before 2000 and it seems to apply to Japan too, AND to software though I need to do further research on this.
Sony's numbers appear to be even more overblown as they included faulty manufactured units.
Sega's seem to be the most honest, they seem to have actually given shipped to retailers figures and I have data that says 1.45m CDs were shipped to N. America and I think it's accurate, if there were hybrids they may not be included in that figure though.
