Coldplay's Mylo Xyloto is the first album to sell more than 80,000 digital copies a week in the UK

"Coldplay’s latest album, 'Mylo Xyloto', smashed a new digital record in landing the Number 1 spot in yesterday’s Official Albums Chart, the Official Charts Company can confirm today.
The new studio album scored the biggest one week digital albums tally of all time in the UK – becoming the first album to top 80,000 downloads in a week as it did so. 'Mylo Xyloto' tallied just over 83,000 digital sales last week, on the way to totalling 208,000 copies overall.
The biggest previous weekly digital tally by any album was 79,800, which was achieved by Take That’s 'Progress' in its opening week, in November last year. The only other artist albums to total more than 50,000 downloads in a week are Adele’s '21' which sold 76,000 downloads in its debut week in January this year, along with Lady Gaga’s 'Born This Way', which sold 57,000."
