Avatar sets Blu-ray sales record
Avatar maintained its popularity in the move from box office to home video, with sales of 6.7 million DVDs and Blu-ray discs in the first four days.
Twentieth Century Fox announced that James Cameron's sci-fi epic sold 2.7 million Blu-rays and four million DVDs since April 22.
The combined US sales brought in 130 million US dollars.
The studio said Avatar became the fastest-selling Blu-ray of all time.
No announcement was made regarding a 3-D DVD release, but a Fox spokesman said one can be expected in the future.
