The X Factor final this weekend may have been a bit snoresome (sorry: ‘credible’ and ‘authentic’), but victor James Arthur has scored a big digital hit with his winner’s single. The Official Charts Company reported yesterday that between Sunday night and midnight on Monday, ‘Impossible’ sold 187k copies in the UK, all downloads, since the CD isn’t being released until today. The OCC notes that the previous best total at this stage for an X Factor winner was 2008, when Alexandra Burke sold 147k copies of her winner’s single by the end of Monday. Last year, Little Mix shifted a mere 69k copies by this point in the week. OCC boss Martin Talbot suggests that for all the talk of waning audience figures for this year’s show, X Factor “remains the pre-eminent launch pad for new artists”. Although as ever, it’s what Arthur does later in 2013 with a full album that will the proof of that. Meanwhile, there were signs this year that X Factor’s magic doesn’t work for all its guest artists – for example with an infamously poor chart showing for No Doubt following their appearance on the show.
