Adele's '21' Becomes First Album to Sell More Than 3 Million Digital Copies It's been almost three years and Adele's last album, 21, is still going strong. The sophomore effort from the English singer has become the first record to sell more than three million digital copies. Nielsen SoundScan reported the feat to Rolling Stone, who notes, "21 surpassing the three million digital sales mark seems like more of an inevitability than a surprise: The record continued to sell well in 2013." The album was a smash success upon its release in 2011, becoming the best-selling album of the 21st century in Britain and racking up five Grammy awards the following year, including Album of the Year, Record of the Year and Song of the Year for the single "Rolling in the Deep." The title came from the age Adele was when she recorded the tracks Adele - who also won a Best Original Song Oscar in 2013 for her James Bond theme-tune, "Skyfall" - is due to release a new album soon, possibly this year.
