Platinum is the least reactive metal. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequently, platinum is often found chemically uncombined as native platinum. Because it occurs naturally in the alluvial sands of various rivers, it was first used by pre-Columbian South American natives to produce artifacts. It was referenced in European writings as early as 16th century, but it was not until Antonio de Ulloa published a report on a new metal of Colombian origin in 1748 that it became investigated by scientists.
Platinum is a barbershop quartet, created in 1998 and the 2000 SPEBSQSA international quartet champions. They are famous for their long posts (held notes at the end of songs), particularly in their adaptation of the song Be Our Guest and in Clay Hine's arrangement of Auld Lang Syne, which is on Platinum's CD of the same name.
Platinum was notable for scoring the most points for a single song in the history of the contest with their rendition of Cuddle Up A Little Closer, Lovey Mine, in which they scored 1438 points out of a possible 1500.
Almost all countries follow variations of the RIAA certification categories, which are named after precious materials.
The number of sales or shipments required for these awards depends upon the population of the territory in which the recording is released. Typically, they are awarded only to international releases and are awarded individually for each country in which 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 record awards were presented to artists by their own record companies to publicize their sales achievements. The first of these was awarded by RCA Victor to Glenn Miller in February 1942, celebrating the sale of 1.2 million copies of "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.
