The CD

With laser discs like CDs, DVDs and CD-ROMs computer usage and program development took on a new momentum in the 1990s. You could store and distribute digital information on them in the form of music, movies, games and software.

The laser disc has small bumps underneath, digital codes for data such as audio or video. A laser beam reads the bumps and they are decoded by a player which enables the disc´s contents to be accessed.

The first laser disc for movies came in 1978. It was as big as an LP and analogue. But it was in 1982 when the smaller CD discs with music began to be sold that the laser disc first became a success. The first CD which was pressed for the market was ABBA's The Visitors. Movies on DVD became popular in the 2000s.
