What is the difference between the DVD and Blu-Ray Disc?

To be simple, Blu-Ray DVD uses a blue-violet laser as opposed to the red laser used on DVDs and it can hold a lot more information on them than DVDs, 25GB (single-layer)/50GB (dual-layer) but DVD and only take 4.7GB (single-layer)/8.5GB (dual-layer).
The images on blu-ray disc are sharper, brighter, and more detailed than any DVD movie. What manufacturers are trying to do is make the movie look as close to what you see in a real theater as possible, except for its a tenth the size and in your home.
