The Fame (Monster) sales breakdown for all the non-believers
2008 - ~0.25M (didn't chart)
2009 - 5.9M
2010 - 5.9M
2009/2010 - 2M sold by 'Monster' EP (released separately in US and Japan, sold ~1.6M in the US to date, you can see it charted separately HERE)
2011 - 1.5M + 0.25M (since it left the chart before the year ended but kept selling)
2012 - 0.2M
And considering MT doesn't count some charts, it might have sold even a bit more, but I DIDN'T want to inflate.
With the average per show of her first arena headlining tour being over 1.1 million and that of 2nd one projected to be 2-3 million.For those who'll try by coming up w/ 'Ooh she had 543189 dates'.
