Basically shows the yearly accumulated marketshare of each console. Obviously we don't have much of 2008 data, nor any 2009/2010 data, but it's from my (being updated) comparisons, so it's in there for when we get to that point. I have 2 other graphs that show yearly marketshare in each region, but it's too big and i can't seem to shrink it down. It shows the breakdown of sales for each year. I'll continuing trying though.
Edit: Here's a link to the last graph, if anyone wishes to see it.
