(2) (Long Play) A vinyl recording of music in analog format that rotates at 33 1/3 RPM (for details of the analog method, see vinyl record). Mono LPs were introduced in the late 1940s, and stereo LPs in 1958. Two-channel stereo was accomplished by creating a V groove with left and right channels at 90 degree angles. The "long" play refers to the slower 33.3 RPM compared to 78 RPM records. The slower rotation increased the recording time per side from five minutes on a 78 to a half hour for the LP. Made of shellac resin, 78 records were brittle and easily breakable, but they were the primary music disc from the start of the 20th century until the late 1950s. The vinyl construction of the LP made it much more durable. Vinyl was also used for 45 RPM records, which were introduced in the late 1940s. A Definite Revival Although eclipsed by CDs in the 1980s, vinyl LPs have been making a comeback in the 21st century, and many individuals cling to their vinyl record collections. A large number of LP phonograph turntables, both consumer grade and high-end audiophile quality, are being manufactured. After years of listening to digital music, which many people feel is much harsher than analog, aficionados continue to enjoy vinyl recordings. See vinyl record, stylus, turntable and Burwen Bobcat.
