RIAA certification
The first official designation of a "gold record" by the Recording Industry Association of America (RIAA) was established for singles in 1958, and the RIAA also trademarked the term "gold record" in the United States. On 14 March 1958, the RIAA certified its first gold record, Perry Como's hit single "Catch a Falling Star". The Oklahoma! soundtrack was certified as the first gold album four months later. In 1976, RIAA introduced the platinum certification, first awarded to the Eagles compilation album Their Greatest Hits (1971–1975) on 24 February 1976, and to Johnnie Taylor's single "Disco Lady" on 22 April 1976. As music sales increased with the introduction of compact discs, the RIAA created the Multi-Platinum award in 1984. Diamond awards, honoring those artists whose sales of singles or albums reached 10,000,000 copies, were introduced in 1999.
