Apple-Backed Blu-ray HD Disc Leads in HD Format Race

So far consumers have chosen Blu-ray HD Disc format over the rival HD-DVD format in the marketplace for high definition DVDs. Blu-ray got a huge boost from being packaged with 1 million Sony Playstation 3 (PS3) game machines sold in the US. The Blu-ray format is supported by Apple and Sony and others, including 7 of 8 major movie studios. Blu-ray uses a blue laser with a shorter wave length that the common red laser so it can pack more information in a given space. [Dana Baggett]
