Relative to its time, which console was more dominant...NES or PS2?

NES sold ~ 60M. Its competition totalled out ~ 13M. That's a 82% marketshare.

The Ps2 will end at ~ 140M, or slightly less. Its competition sold 56M. That's a 70% marketshare.

Where'd you get those numbers for the competition? I've never been able to find numbers for the Master System and the 7800
