Coldplay are a British rock band formed in 1996 by lead vocalist and keyboardist Chris Martin and lead guitarist Jonny Buckland at University College London. They achieved worldwide fame with the release of the single "Yellow" in 2000. This was followed by their debut album Parachutes released the same year, which was nominated for the Mercury Prize. The band has won 62 awards from 209 nominations throughout their career. Coldplay have sold more than 80 million records worldwide, making them one of the world's best-selling music artists. Despite their worldwide popularity, the band has remained protective of how their music is used in the media, refusing its use for product endorsements. In the past, Coldplay turned down multi-million dollar contracts from Gatorade, Diet Coke, and Gap, who wanted to use the songs "Yellow", "Trouble", and "Don't Panic" respectively. During the early years, Coldplay became widely known in the media for giving 10 per cent of the band's profits to charity, which they continue to do.
