Record sales

Music recording sales certification is a system of certifying that a music recording has shipped or sold a certain number of copies. The threshold quantity varies by type (such as album, single, music video) and by nation or territory (see List of music recording certifications).

Almost all countries follow variations of the RIAA certification categories, which are named after precious materials (gold, platinum and diamond).

The number of sales or shipments required for these awards depends upon the population of the territory where the recording is released. Typically, they are awarded only to international releases and are awarded individually for each country where the album is sold. Different sales levels, some perhaps 10 times lower than others, may exist for different music media (for example: videos versus albums, singles, or downloads).

The original gold and silver record awards were presented to artists by their own record companies to publicize their sales achievements. The first silver disc was awarded by Regal Zonophone to George Formby in December 1937 for sales of 100,000 copies of "The Window Cleaner". The first gold disc was awarded by RCA Victor (under division imprint Bluebird Records) to Glenn Miller and His Orchestra in February 1942, celebrating the sale of 1.2 million copies of single "Chattanooga Choo Choo". Another example of a company award is the gold record awarded to Elvis Presley in 1956 for one million units sold of his single "Don't Be Cruel". The first gold record for an LP was awarded by RCA Victor to Harry Belafonte in 1957 for the album Calypso (1956), the first album to sell over 1,000,000 copies in RCA's reckoning.
