Most of the top-selling bands in the world sell their music through iTunes, but it was Adele that became the first to break the double platinum sales plateau.

Columbia Records said on Wednesday that since the singer won six Grammy Awards and performed “Rolling in the Deep,” Adele had her biggest sales week ever, selling 730,000 copies of her album.

The double platinum means that Adele sold more than 2 million copies of the album, all within a year of its initial release.

Columbia Records also noted that the album is in its 21st non-consecutive week at No. 1 on The Billboard Top 200 Album Chart, and that 21 is the longest running #1 by a woman in Billboard’s nearly 56 year history.

The album has been certified 7x Platinum in the U.S. and has sold over 18 million copies worldwide. The album has over 16 million singles sold in the US alone, including 7x Platinum certified “Rolling in the Deep,” 4x Platinum certified “Someone Like You,” 2x Platinum certified “Set Fire to the Rain” and Gold certified “Rumour Has It.”
