Blu-ray Disc (also known as Blu-ray or BD) is an optical disc storage medium designed to supersede the standard DVD format. Its main uses are for storing PlayStation 3 games, high-definition video, and data storage, with up to 50 GB per disc. The disc has the same physical dimensions as standard DVDs and CDs.
The name Blu-ray Disc derives from the blue-violet laser used to read the disc. While a standard DVD uses a 650 nanometre red laser, Blu-ray uses a shorter wavelength, a 405 nm blue-violet laser, and allows for almost six times more data storage than on a DVD.
During the format war over high-definition optical discs, Blu-ray competed with the HD DVD format. Toshiba, the main company supporting HD DVD, ceded in February 2008, and the format war ended,[2] then in July 2009, announced plans to put out its own Blu-ray Disc device by the end of 2009.[3]
Blu-ray Disc was developed by the Blu-ray Disc Association, a group representing makers of consumer electronics, computer hardware, and motion pictures. As of June 2009, more than 1000 Blu-ray disc titles are available in Australia, 2500 in Japan, 1500 in the United Kingdom, and 2500 in the United States and Canada.

@showmetheinuyasha You are right. The bluray format is uncompressed, so of course the image quality is better than it is on youtube (which is compressed). But it helps give you an idea for those who are new to bluray.
