What is the meaning of DVD ?
Question: I want to Know the meaning of DVD
Answers: DVD (also known as Digital Versatile Disc or Digital Video Disc ) is an optical disc storage media format that can be used for data storage, including movies with high video and sound quality. DVDs resemble compact discs as their physical dimensions are the same (120 mm (4.72 inches) or occasionally 80 mm (3.15 inches) in diameter) but they are encoded in a different format and at a much higher density. The official DVD specification is maintained by the DVD Forum.
In the early 1990s two high-density optical storage standards were being developed: one was the MultiMedia Compact Disc (MMCD), backed by Philips and Sony, and the other was the Super Density disc (SD), supported by Toshiba, Time-Warner, Matsushita Electric, Hitachi, Mitsubishi Electric, Pioneer, Thomson, and JVC. IBM's president, Lou Gerstner, acting as a matchmaker, led an effort to unite the two camps behind a single standard, anticipating a repeat of the costly format war between VHS and Betamax in the 1980s.
Philips and Sony abandoned their MMCD format and agreed upon Toshiba's SD format (not to be confused with secure digital cards) with two modifications that are both related to the servo tracking technology. The first one was the adoption of a pit geometry that allows push-pull tracking, a proprietary Philips/Sony technology. The second modification was the adoption of Philips' EFMPlus. EFMPlus, created by Kees Immink, who also designed EFM, is 6% less efficient than Toshiba's SD code, which resulted in a capacity of 4.7 GB as opposed to SD's original 5 GB. The great advantage of EFMPlus is its great resilience against disc damage such as scratches and fingerprints. The result was the DVD specification Version 1.5, announced in 1995 and finalized in September 1996. In May 1997, the DVD Consortium was replaced by the DVD Forum, which is open to all companies.
DVD was originally an initialism for Digital Video Disc. Some members of the DVD Forum believe that it should stand for Digital Versatile Disc to reflect its widespread use for non-video applications. Toshiba, which maintains the official DVD Forum site [1], adheres to the latter interpretation, and indeed this appeared within the copyright warnings on some of the earliest examples. However, the DVD Forum never reached a consensus on the matter, and so today the official name of the format is simply DVD ; the letters do not officially stand for anything.[2]
Warner Home Video and Toshiba introduced the new format to Wall Street types, Hollywood big wigs and the investment community at an elaborate staged event on the Warner Bros. lot, hosted by Warner Home Video then President Warren Lieberfarb. The production included the first ever interactive DVD menu designed by producer Billy Pollina. The first DVD players and discs were available in November 1996 in Japan, March 1997 in the United States, 1998 in Europe and in 1999 in Australia. The first pressed DVD release was the film Twister in 1996. The film had the first test for 2.1 surround sound. The first titles released in the U.S., on March 19, 1997, by Lumivision, authored by AIX Entertainment, were IMAX adaptations: Africa: The Serengeti, Antarctica: An Adventure of a Different Nature, Tropical Rainforest, and Animation Greats.
By the spring of 1999 the price of a DVD player had dropped below $300 US. At that point Wal-Mart began to offer DVD players for sale, but DVDs represented only a small part of their video inventory; VHS tapes of films made up the remainder. Wal-Mart's competitors followed suit, and DVDs began to increase in popularity with American consumers.

nowadays dvd's are mostly used either for games or movies and other media.
the capacity of a single layer dvd is 4.2 GB approx
and that of a dual layered dvd is 8.5 GB.
the craving for more data in lesser space has lead us to the discovery of bluray disc(sony) and hd-dvd (toshiba)
which boast of storage in excess of 25 GB!!
this is the future of optical media.
