The first Blu-ray Disc titles were released on June 20, 2006: 50 First Dates, The Fifth Element, Hitch, House of Flying Daggers, Underworld: Evolution, x Xx (all Sony), Twister (Warner Bros.), and MGM's The Terminator.The DVD Forum, chaired by Toshiba, was split over whether to develop the more expensive blue laser technology.Following protracted development, blue laser diodes operating at 405 nanometers became available on a production basis.Sony started two projects in collaboration with Philips a format of rewritable discs that would eventually become Blu-ray Disc (more specifically, BD-RE). The first DVR Blue prototypes were unveiled at the CEATEC exhibition in October 2000 by Sony.Triple-layer discs (100 GB) and quadruple-layer discs (128 GB) are available for BD-XL re-writer drives.High-definition (HD) video may be stored on Blu-ray discs with up to 2160p resolution (3840×2160 pixels) and at up to 60 frames per second.DVD-Video discs were limited to a maximum resolution of 480p (NTSC, 720×480 pixels) or 576p (PAL, 720×576 pixels).Besides these hardware specifications, Blu-ray is associated with a set of multimedia formats.
HD DVD had a head start in the high-definition video market, as Blu-ray Disc sales were slow to gain market share.This effectively included other studios that came under the Warner umbrella, such as New Line Cinema and HBO—though in Europe, HBO distribution partner, the BBC, announced it would, while keeping an eye on market forces, continue to release product on both formats.This led to a chain reaction in the industry, with major U. retailers such as Best Buy, Walmart, and Circuit City and Canadian chains such as Future Shop dropping HD DVD in their stores.On October 4, 2004, the name "Blu-ray Disc Founders" was officially changed to the Blu-ray Disc Association (BDA), and 20th Century Fox joined the BDA's Board of Directors.In January 2005, TDK announced that they had now developed an ultra-hard yet very thin polymer coating ("Durabis") for Blu-ray discs; this was a significant technical advance because a far tougher protection was desired in the consumer market to protect bare discs against scratching and damage compared to DVD, while technically Blu-ray Disc required a much thinner layer for the denser and higher frequency blue laser.Blu-ray or Blu-ray Disc (BD) is a digital optical disc data storage format.It was designed to supersede the DVD format, in that it is capable of storing hours of video in high-definition (HDTV 720p and 1080p) and ultra high-definition resolution (2160p).In March 2002 the forum approved a proposal, which was endorsed by Warner Bros. The proposal involved compressing HD video onto dual-layer standard DVD-9 discs.In spite of this decision, however, the DVD Forum's Steering Committee announced in April that it was pursuing its own blue-laser high-definition video solution.At CES 2007, Warner proposed Total Hi Def—a hybrid disc containing Blu-ray on one side and HD DVD on the other, but it was never released.In a June 28, 2007, press release, Twentieth Century Fox cited Blu-ray Disc's adoption of the BD anticopying system as key to their decision to support the Blu-ray Disc format.
