The '''Blu-ray Disc''' is an optical disc type primarily used for videos, created as a higher-capacity successor to the [[DVD]]. For a time it was in a format war with [[HD-DVD]], ultimately winning out, but this victory came in a time when physical media were in decline in favor of streaming and downloads through networks as the preferred means of content distribution. This has slowed the adoption of Blu-ray compared to earlier media, but the format is widely supported nevertheless. Netflix has an option to receive Blu-ray Discs instead of DVDs when available, as part of the disc-in-the-mail subscriptions (which continue to have a wide range of material not presently available in streaming subscriptions).

Blu-ray Discs can be single-layer (25 GB capacity) or double-layer (50 GB). As with other optical disc types, they can be used for data, games, or audio, but the format is primarily marketed as a medium for video such as movies and TV shows.

The archival-quality [[M-Disc]] is available in BluRay form as well as DVD.
