in a commercial way in the early 1980s with the development and release of the compact disc (CD). It appears that the CD is only the beginning, however, as
digital audio recording continues to progress. It provides convenience, reliability and lower production costs, but it is certain that copyright holders have not yet finished trying to mold its
applications into forms most profitable for them. Audio Recording Thomas Edison enabled the recording of sounds with his phonograph, invented in 1877.
Concentrated sound waves caused a stylus to vibrate against soft tin, etching a channel in the tin. Another stylus could travel the channel to produce playback of the sounds
recorded on the tin. As could be expected, sound quality was unacceptable for any application that Edison could envision for the device, and he moved on to other projects.
More than a decade later, Emil Berliner improved the phonograph with alterations that created the gramophone, which replaced Edisons cylinder surface with a
flat disc as the recording surface and a finer needle that could produce a greater range of nuances in the sounds recorded. Pre-recorded music grew in popularity throughout the
early years of the new century. It reached its peak after reaching a turning point in 1948, when a disc improvement was developed by Columbia Broadcasting System Laboratories.
Until 1948, records were played at 78 rpm, and most were manufactured from a combination of clay and shellac. Columbias contribution was the 33 1/3 rpm LP plastic disc
that held much more music and was much more durable. Radio Corporation of America (now RCA Corporation) introduced the 45 rpm disc in 1949 to compete with the LP.
