High Quality Content by WIKIPEDIA articles! The UK Singles Chart is a music chart compiled by the Official Charts Company that calculates the best-selling singles of the week in the United Kingdom. Since 2005, the chart has been based on the sales of both physical and digital singles, on the condition that the single was available in both formats. In 2007, the rules were changed so that legal downloads of all songs, irrespective of whether a physical copy was available, were eligible to chart. Between 2000 and 2009, ten singles that reached the top of the singles chart sold more than 1 million copies in the United Kingdom. At the end of the decade, a retrospective chart was compiled by the Official Charts Company to determine the best-selling single of this ten-year period. The title was won by Will Young, the winner of the televised talent competition Pop Idol in 2001, with his double A-side single "Evergreen" / "Anything Is Possible", released in 2002.
