Adele's Grammy-winning '21' becomes 21st album to sell 10 million copies

Adele's '21' becomes 21st album to sell 10 million copies, according to Billboard.

The album sold 28,000 copies last week for a total of 10,020,000, according to Nielsen SoundScan.

That makes it the 21st album to reach the 10 million mark since SoundScan began tabulating data in 1991, according to Billboard.

"21" has not fallen off the Billboard chart since its release Feb. 22, 2011 -- 92 weeks ago.

Adele is currently riding the Hot 100 with "Skyfall," the title song from the James Bond film of the same name. ("Skyfall" is not on the "21" album.) The single debuted at No. 8 in October.
