Globally historic highest sales year = 1 (base). The world saw more CD sales in 2000 than any other year, so we are normalizing sales for the year 2000. I can normalize them for 2015, too. It's pretty arbitrary, but the ratios will stay the same regardless.
EDIT:
Plain text, adjusted for 2015 numbers. The equivalent to 4,294,000 in 2001 is just 757,000 in 2015.
