Blu-ray Disc (BD or Blu-ray) is a high-definition home entertainment format on the standard 120mm optical discs. Launched in 2006, it competed briefly, but fiercely from 2006 to 2008 with HD DVD before becoming the standardized high-definition home entertainment format.
Blu-ray releases, much like DVDs are divided into separate regions, to restrict the areas specific discs can be played. The following is a guide to the regions and which areas of the world they relate to:
