Blue-ray vs HD DVD Format war move closer to an end

January 16, 2008
Blue-ray and HD DVD are two divergent high-density optical disc formats for the storage of digital information, including high-definition video. For a couple of years now there has been a war of sorts going on between the Blue-Ray and HD DVD camps to gain dominance over how people would view future digital entertainment.

Of late, the HD DVD format has taken a beating with Warner Bros. deciding to release all its movies exclusively in Blue-ray format. Now only Universal, Paramount Pictures and a few minor ones from the movie industry are still in the HD DVD camp with 20th Century Fox,New line, Sony Pictures, Buena Vista and of course Warner Bros firmly entrenched in the Blue-ray camp. This means that over 70% of Hollywood's movie output will be released in Blue-ray discs.
