Blu-ray is one of two high-definition disc formats introduced to consumers in 2006. Along with its rival, HD-DVD, Blu-ray expanded the depth, color, and detail of the images you see. Although HD-DVD was discontinued in 2008, Blu-ray and DVD are still in use today. Here's a look at the history of Blu-ray and where it stands today.
Blu-ray As Soon As Possible
DVD technology improved upon earlier formats, such as VHS and Laserdisc, in terms of the television viewing and listening experience. However, DVD is not a high-definition format. Its limitations became apparent as HDTV emerged, TV screen sizes increased, and video projectors became more common.
Blu-ray was meant to solve the shortcomings of DVD. It shows you more depth, a wider range of color shades and more image detail.
DVD uses red laser technology. The Blu-ray Disc format uses blue laser technology and advanced video compression to achieve high-definition video playback on a standard DVD-format disc.
