A gramophone recor (also vinyl record, vinyl, phonograph record, or simply record) is an analogue sound storage medium consisting of a flat disc with an inscribed modulated spiral groove usually starting near the periphery and ending near the center of the disc. (Some commercial-use only records ran the groove from the center to the edge of the record.) Gramophone records were the primary medium used for commercial music reproduction for most of the 20th century. They replaced the phonograph cylinder as the most popular recording medium in the 1900s, and although they were supplanted in popularity in the late 1980s by digital media, they continue to be manufactured and sold as of 2008. Gramophone records remain the medium of choice for many audiophiles, and specialist areas such as electronic dance music and hip hop.
