Given a reference text about the Recording Industry Association of America (RIAA) awards, tell me how many albums need to be sold to get an award.
As of 1989, a song or album needed to exceed a sales threshold of 500,000 for Gold and 1,000,000 for Platinum. In 1999 after a growth in music sales, the Diamond award was introduced for songs or albums that sold over 10,000,000 units.
