In fact, James Cameron’s movie has claimed the honor of best-selling Blu-ray movie ever, beating the previous title-holder, The Dark Knight](http://playstation.joystiq.com/2008/12/11/the-dark-knight-fastest-selling-blu-ray-of-all-time-over-25-fo/). According to a report by Variety, 2.7 million Blu-ray discs were sold in the four days since its retail release in the US. (In comparison, The Dark Knight took 18 months to sell 2.5 million discs.)
Perhaps a testament to the growing demand for Blu-ray content, Blu-ray accounted for 40% of total home video sales for Avatar in the four-day window. That’s a significant increase from the 25% market share The Dark Knight claimed over a year ago.
