VINYL HISTORY

Groovy Baby - Dean Martin French Style

In 1930, RCA Victor launched the first commercially-available vinyl long-playing record, marketed as "Program Transcription" discs. These revolutionary discs were designed for playback at 33⅓ rpm and pressed on a 12" diameter flexible plastic disc. In Roland Gelatt's book The Fabulous Phonograph, the author notes that RCA Victor's early introduction of a long-play disc was a commercial failure for several reasons including the lack of affordable, reliable consumer playback equipment and consumer wariness during the Great Depression. A good outline of this unsuccessful product launch can be found at the following site.
However, vinyl's lower playback noise level than shellac was not forgotten. During and after World War II when shellac supplies were extremely limited, some 78 rpm records were pressed in vinyl instead of shellac (wax), particularly the six-minute 12" (30 cm) 78 rpm records produced by V-Disc for distribution to US troops in World War II.
Beginning in 1939, Columbia Records continued development of this technology. Dr. Peter Goldmark and his staff undertook exhaustive efforts to address problems of recording and playing back narrow grooves and developing an inexpensive, reliable consumer playback system. In 1948, the 12" (30 cm) Long Play (LP) 33⅓ rpm microgroove record was introduced by the Columbia Record at a dramatic New York press conference.
The commercial rivalry between RCA Victor and Columbia Records led to RCA Victor's introduction of what it had intended to be a competing vinyl format, the 7" (17.5 cm) / 45 rpm Extended Play (EP). For a two-year period from 1948 to 1950, record companies and consumers faced uncertainty over which of these formats would ultimately prevail in what was known as the "War of the Speeds".
Eventually, the 12" (30 cm) / 33⅓ rpm LP prevailed as the predominant format for musical albums, and the 7" (17.5 cm) / 45 rpm EP or "single" established a significant niche for shorter duration discs typically containing one song on each side. The EP discs typically emulated the playing time of the former 78 rpm discs, while the LP discs provided up to one-half hour of time per side.
After the introduction of high-quality but expensive stereo reel-to-reel tapes in 1955 and the increasing public fascination with stereo sound, intense work was undertaken to devise a scheme for recording stereo sound on 12" (30 cm) / 33⅓ rpm LP. In late 1957, a system of cutting and playing back stereo was devised and generally accepted by the industry. Consumer acceptance of stereo LPs was somewhat cautious initially but grew steadily during the early 1960s, and the industry largely discontinued production of conventional monaural LP records and playback equipment by 1968.
Similarly, the introduction of high-quality but expensive quadraphonic (four channel) reel-to-reel tapes and 8-track tape cartridges in 1970 led to the introduction of quadraphonic vinyl records, which arrived on the market in 1972. Although public interest was initially high, the lack of compatibility between the three competing SQ, QS, and CD-4 formats prompted the eventual commercial failure of quadraphonic LP records. Most record companies stopped producing quadraphonic LPs after 1975 although a handful of classical-music titles continued to be issued until 1980.
