As the winner of the high definition optical disc format war, the Blu-ray Disc was introduced on June 20, 2006, which, like the HD DVD, provides high definition video and audio. The resolution of the film can go between 480p, 576p, 720p, 1080i, or 1080p.

Each disc can carry up to 25 (Single Layer) or 50 GB (Dual Layer), as well as up to 32 audio tracks, and a whopping 255 subtitle tracks, but they cannot carry closed captions, because HDMI does not support Line 21, like PAL DVDs don't either.

The audio quality for Blu-ray Discs can either be Dolby Digital, LPCM, Dolby TrueHD, DTS-ES, or best of all, DTS-HD Master Audio, which is used on all movies played in theaters by today's standards.

Movie studios began offering Blu-ray Discs of their films in 2006, starting with Sony Pictures Home Entertainment on June 20, followed by Warner Home Video on August 1, then Walt Disney Home Entertainment on September 19, Paramount Home Entertainment on September 26, 20th Century Fox on November 21, and finally, Universal Studios Home Entertainment in June 2008.

The regional lockout for Blu-ray Discs is different compared to DVDs. Instead of using numbers, they use letters:

BD region DVD region Countries
A 1 United States, Canada
A 4 Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay, Venezuela
A 2 Japan
A 3 Hong Kong, Indonesia, Malaysia, Philippines, Singapore, South Korea, Taiwan, Thailand, Vietnam
B 2 United Kingdom, France, Germany, Italy, Czech Republic, Denmark, Finland, Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland, Turkey, Belgium, Bulgaria, Croatia, Greece, Hungary, Iceland, Ireland, Israel, Kuwait, Qatar, Romania, Serbia, Slovakia, Slovenia
B 4 Australia, New Zealand
B 5 Estonia, Latvia, Lithuania, Ukraine
C 5 Russia, India
C 6 People's Republic of China

The following languages are used in each region:

A/1
A/4
English, French (Canada), Portuguese (Brazil), Spanish (Latin America)
A/2 Japanese
A/3 Cantonese, Chinese (Simplified), English (Malaysia/Philippines/Singapore), Indonesian, Mandarin (Traditional), Korean, Malay, Thai, Vietnamese
B English, French, German, Italian, Czech, Danish, Dutch, Finnish, Norwegian, Polish, Portuguese, Spanish (Castilian), Swedish, Turkish, Arabic, Bulgarian, Croatian, Estonian, Greek, Hebrew, Hungarian, Icelandic, Latvian, Lithuanian, Romanian, Serbian, Slovak, Slovenian and Ukranian
C Russian, Chinese (Putonghua), Hindi

DVDs are backwards compatible with Blu-ray players, but a standard DVD player cannot play Blu-ray Discs due to the red laser used in DVD players too large to read the tiny grooves in a Blu-ray Disc.
