Which is the best – selling digitally downloaded album of all time?

Adele met great success with “21″ and  earned numerous mentions in the Guinness World Records.

She is the first artist to sell more than 3 million copies of an album in a year in the UK and “21” was the best-selling album of 2011 in the United States, as well as the best – selling digitally downloaded album of all time.

With her two albums and the first two singles from 21, “Rolling in the Deep” and “Someone Like You”, she became the first living artist to achieve the feat of having two top-five hits in both the UK Official Singles Chart and the Official Albums Chart simultaneously since The Beatles in 1964!
