The name Blu-ray is derived from the underlying technology, which utilizes a blue-violet laser to read and write data. The name is a combination of "Blue" (blue-violet laser) and "Ray" (optical ray). According to the Blu-ray Disc Association the spelling of "Blu-ray" is not a mistake, the character "e" was intentionally left out so the term could be registered as a trademark.

The correct full name is Blu-ray Disc, not Blu-ray Disk (incorrect spelling)
The correct shortened name is Blu-ray, not Blu-Ray (incorrect capitalization) or Blue-ray (incorrect spelling)
The correct abbreviation is BD, not BR or BRD (wrong abbreviation)

so here you go now you know why they call it blu-ray technology I hope that you have a wonderful day and if there is anything that I can research for you let me know thanks

DVDs don't offer the movie studios enough DRM, that's the jist of it. The quality of HDDVD formats is slightly higher of that of standard DVD, but not enough to justify an upgrade, especially at the cost of digital rights.

A Blu-ray Disc (BD) is a next-generation optical disc format meant for high-density storage of high-definition video and data. The Blu-ray standard was jointly developed by a group of consumer electronics and PC companies called the Blu-ray Disc Association (BDA), spearheaded by Sony. It is currently competing with the HD DVD format for wide adoption as the preferred next generation optical standard, similar to the videotape format war (in which VHS -- originally from JVC -- ultimately gained market supremacy over Betamax (sponsored and exclusively controlled by Sony)), or the vinyl format war between the 45rpm 'single' (supported by RCA) and the 33 1/3rpm LP (supported by Columbia Records)). As of 2006, neither format has succeeded in supplanting the present home video standard, the DVD.

The name Blu-ray is derived from the blue-violet laser it uses to read and write to the chalcogenide disc. A Blu-ray Disc can store substantially more data than a DVD, because of the shorter wavelength (405 nm) of the blue-violet laser (DVDs use a 650-nm-wavelength red laser and CDs an infrared 780 nm laser), which allows more information to be stored digitally in the same amount of space. In comparison to HD DVD, which also uses a blue laser, Blu-ray has more information capacity per layer (25 gigabytes instead of 15) but may initially be more expensive to produce.
