Activision announced this morning that, according to data garnered from the NPD, ChartTrack, GfK and internal estimates, the Call of Duty franchise has accumulated $3 billion-with-a-b in sales over its lifetime. As all but the densest among you have likely deduced, CoD was put over the top by the release of Modern Warfare 2, which moved $550 million in its first five days on sale.

For a bit of perspective, $3 billion is pretty darn close to the gross domestic product of the Kingdom of Swaziland, a comparison that's especially appropriate when you realize that 54 percent of Swazis have a Gamerscore over 20,000. ... Oh, wait, this doesn't say "a Gamerscore over 20,000," it says "access to clean water." Sorry, smudge on the page.
