The Chart upset of the decade came in December, as the Christmas number one was achieved not by the X Factor winner, Joe McElderry but by 1990s rap metal band Rage Against the Machine. A Facebook group, set up to halt "Simon Cowells stranglehold on the charts" by getting the 1992 "Killing in the Name" to the top of the charts, got 750,000 members and led Rage Against the Machine to the first download-only Christmas number one, selling over 500,000 copies – ahead of Joe McElderry by 50,000. In the following week's chart (week ending 2 January 2010) McElderry's single, "The Climb" made it to the number one spot.
