Since Nielsen SoundScan began to track music sales in 1991, AC/DC have sold over $26.4? million worth of albums, making their sales figures second only to The Beatles, outselling both The Rolling Stones and The Who. Over the last five years, as CD sales have declined in general, AC/DC albums have sold just as well or better. They sold over 1.3 million CDs in the US during 2007 despite not having released a new album since 2001 at that point.[77]
In 2009 the Recording Industry Association of America upgraded the group's US sales figures from 69 million to 71 million, making AC/DC the fifth-best-selling band in US history and the ninth-best-selling artist, selling more albums than Madonna, Mariah Carey and Michael Jackson.[6] The RIAA also certified Back in Black as double Diamond (20 million) in US sales, and by 2007 the album had sold 22 million copies, which moved it into fifth place.[8]
