Q: Why is it called Blu-ray?
A: This is because Blu-ray Disc players and PC drives, and also Sony’s PlayStation 3, use a blue laser beam to read data from discs. DVD´s used a red laser. A blue laser can be focused more tightly, so disc makers can put much more data on a disc the same size as a DVD. Blu-ray Discs can hold up to 50 gigabytes, compared to a DVD, which holds less than 10 GB. With the extra space the video can have up to six times the resolution of DVD, plus you get supplementary bonus features and improved surround soundtracks.

There was much controversy between the Blu-ray DVD and standard DVD and became a “format war” in many ways. However, obviously the Blu-ray has won. Some features are available with the Blu-Ray DVD and standard DVDs just do not.
