The History of Home Video Entertainment


History of home video entertainment begins with the Video Home System, VHS, a recording and playing standard medium developed by Japan Victor Company (JVC), first launched in 1976. There is also competitive product to this, Betamax, which was produced by Sony. VHS initially offered a longer playing time than the Betamax system, and had the advantage of a far less complex tape transport mechanism. This two products use magnetic tape as a medium. The VHS cassette made from plastic clamshell.

The Laserdisc (LD) is the first commercial use of optical disc storage medium. The standard home video laserdisc is 30 cm, in diameter and made up of two single-sided aluminum discs layered in plastic and bonded with glue. After that, this optical disc storage has been reduced by size from 30 cm to 12 cm Video CD format. Video CD, VCD, also known as View CD, is a standard digital format for storing video on a Compact Disc. The latest development of optical disc storage medium is DVD (also known as "Digital Versatile Disc" or "Digital Video Disc, which is a popular optical disc storage media format. Its main uses are video and data storage. Most DVDs are of the same dimensions as Video CD, but DVD can store more than six times as much data, with better quality. By 2006, most major film studios stopped releasing new movie titles in VHS format, opting for DVD only releases. Many retailers have stopped selling pre-recorded movies on VHS.
