Time is running out for Blu ray format

Time is running out for Blu-ray discs, the high definition (HD) format that are supposed to be replacing the DVD.Despite the launch of new Blu-ray players and talk of rising sales at the Consumer Electronics Show in Las Vegas, manufacturers know they are in a race to make a real impact on the market before the new kid on the block, downloading or streaming HD films directly from the internet, consigns the format to a footnote in video history.Blu-ray discs have the same physical dimensions as a DVD, but provide better quality sound and pictures for HD movies, thanks to more expensive laser technology. They were launched nearly three years ago but only became the preferred medium after winning an HD format war a year ago.
