Long Play (LP) Records: The Evolution of the Vinyl Album
The Long Play (LP) format revolutionized how the world consumed music, shifting the focus from single songs to cohesive albums. While it became a commercial powerhouse in the 1950s, the journey to the modern vinyl record was marked by decades of experimentation, technical failures, and eventual triumph over previous audio standards.
Key Facts
- Commercial Debut: The modern LP was unveiled by Columbia Records on June 21, 1948.
- Technical Standard: LPs typically play at 33 1/3 rpm (revolutions per minute).
- Early Pioneer: RCA Victor launched an early version called "Program-Transcription" records in 1931.
- Key Innovator: Peter Goldmark led the Columbia team that developed the successful LP format.
- Modern Resurgence: By 2022, US vinyl sales reached 41 million units, outselling CDs for the first time since 1987.
Early Attempts and Predecessors
Before the LP became a household staple, several companies attempted to extend the playing time of phonograph records. In 1926, Edison Records experimented with discs offering 24 minutes per side. However, these were a commercial failure due to the unreliability of the playback systems, which were primarily wind-up phonographs.
During the 1930s, motion picture studios utilized optical soundtracks for film. To support theaters that still relied on disc-only sound projectors, studios produced 12-inch soundtrack discs by dubbing optical tracks. These were produced as late as 1936 to reduce costs.
The RCA Victor "Program-Transcription" Era
In September 1931, RCA Victor introduced the first commercially available vinyl long-playing record, known as "Program-Transcription" records. These discs played at 33 1/3 rpm and featured finer, more closely spaced grooves than the standard 78-rpm records of the time.
RCA utilized two different materials: shellac for 10-inch discs (popular and light classical music) and a new vinyl-based compound called Victrolac for 12-inch discs (serious classical music). Victrolac provided a significantly quieter playing surface and could hold up to 15 minutes per side. The first 12-inch recording issued was Beethoven's Fifth Symphony, performed by the Philadelphia Orchestra under Leopold Stokowski.
Despite the technical leap, the format failed commercially. The Great Depression and a lack of affordable consumer playback equipment led RCA to delete most of these records by the end of the decade, though development continued until World War II halted progress.
The Birth of the Modern LP
The breakthrough came from CBS Laboratories, where head research scientist Peter Goldmark led a team to create a record capable of holding at least 20 minutes per side. Goldmark delegated the primary experimental work to Howard H. Scott and William S. Bachman.
After research was paused during World War II and resumed in 1945, Columbia Records officially unveiled the LP on June 21, 1948, at the Waldorf Astoria. The launch included 133 recordings across 10-inch and 12-inch formats. The first 12-inch LP was Mendelssohn's Concerto in E Minor, performed by Nathan Milstein with the New York Philharmonic.
The initial 12-inch pressings were made of 220 grams of vinyl. Columbia released several series, including "popular" (starting with Frank Sinatra), "classical" (starting with Beethoven's 8th symphony), and "juvenile" (starting with Gene Kelly).
Market Adoption and the "Album Era"
The transition from the 78-rpm record to the LP was gradual. In 1952, 78s still dominated unit sales in the US, while the LP accounted for less than 17% of units sold. However, the LP's higher price point meant it already represented over 26% of dollar sales.
By 1958, the landscape had shifted dramatically. LPs accounted for 58% of dollar sales, while 78s had plummeted to just 1% of dollar sales. This shift ushered in the "album era," allowing artists to move beyond singles to create concept albums with coherent themes.
| Year | 78-rpm (Unit Sales) | 45-rpm (Unit Sales) | LP (Unit Sales) | LP (Dollar Sales) |
|---|---|---|---|---|
| 1952 | >50% | >30% | <17% | >26% |
| 1958 | 2% | ~73% | ~25% | 58% |
The Decline and Modern Resurgence
The dominance of the LP began to wane in the late 1970s with the introduction of cassette tapes, followed by the digital compact disc (CD) in the 1980s. However, the format never fully disappeared.
The 2010s saw a significant vinyl resurgence. US sales grew from 15.6 million in 2017 to 27 million in 2020. By 2022, sales reached 41 million units, marking the first time since 1987 that the LP outsold the compact disc as the highest-selling physical music format.
