The Blu-ray vs HD DVD format war reaches another milestone, with sales of Blu-ray Discs reaching more than one million sold since the format launched less than a year ago. According to Home Media Research, Blu-ray locked up 70% of high-definition movies sales in the first quarter of 2007 (832,530 to 359,300), and account for seven of the top ten best-selling high-def movies. Even on those few titles available in both formats, like The Departed, consumers are buying more Blu-ray than HD DVD versions. HD DVD owners and fans can still point to sales of their format of choice reaching number one at Amazon recently -- as well as early release dates like The Matrix and exclusives like Smokin' Aces -- but with Blu-ray-only Disney releasing big titles like Cars and both Pirates movies in the coming months, the Blu-ray Disc Association won't be stopping the press releases anytime soon.
