Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about LP record?
Summarize this article for a 10 year old
The LP (from "long playing" or "long play") is an analog sound storage medium, a phonograph record format characterized by: a speed of 33+1⁄3 rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the "microgroove" groove specification; and a vinyl (a copolymer of vinyl chloride acetate) composition disk. Introduced by Columbia Records in 1948, it was soon adopted as a new standard by the entire US record industry. Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it remained the standard format for record albums, during a period in popular music known as the album era. Beginning in the late 1970s, LP sales began to decline because of the increasing popularity of Compact Cassettes, then in the 1980s of compact discs. By 1988, the latter format began to outsell LPs.
