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, originally 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. The single sold just under 1.8 million copies and saw Young finish ahead of fellow Pop Idol finalist Gareth Gates, whose debut single "Unchained Melody" sold 1.34 million copies. Young's single included sales of 1,108,269 copies in its first week, at the time a first-week total that had been bettered only by Elton John's "Candle in the Wind 1997". The X Factor winners Alexandra Burke (5th), and Shayne Ward (8th) and the band formed on Popstars in 2001, Hear'Say (9th), also reached the top ten. Kylie Minogue, Shaggy and Tony Christie were the other solo artists who made the top ten of best-selling singles; Christie's best-seller was a charity single recorded for Comic Relief in 2005. Children's television character Bob the Builder's "Can We Fix It?", voiced by Neil Morrissey, and Band Aid 20's cover of "Do They Know It's Christmas" made up the rest of the top ten singles. The chart is significantly skewed towards singles released at the beginning (2000–2002) and end (2007–2009) of the decade. Digital downloads were included in the charts for the first time in 2005 but it took several years before the download figures made up for the loss of physical single sales. Only six songs released in 2003 and two released in 2004 (including Band Aid 20's million-seller "Do They Know It's Christmas?") made the top 100 best-selling singles, compared with twelve in 2000 and thirteen in 2009. Following changes to the chart ruling in 2007,
