Bluray.com is reporting that Avatar has now sold 6.2 million Blu-ray copies in the first three weeks since launch—that's a steady climb since the 2.7 million sold in the first four days. On top of that, there's another 13.5 million in DVD sales.
Let's just take a second and mull over the money machine that is Avatar. Let's be conservative and use the current price at Amazon for these items, even though most sales would have been for more than this price.
6.2 million blu-rays at $19.99 each = $124 million
13.5 million DVDs at $15.99 each = $216 million
Domestic Box Office = $748 million
International Box Office = $1.97 billion
Grand Total -- $3 billion dollars in sales so far.
Just to put those numbers in perspective, Christopher Nolan's The Dark Knightracked up 16 million sales of both Blu-ray and DVDs together.
James Cameron's epic is now the top-selling Blu-ray release of all time worldwide, and it has no signs of slowing down.
