The First Pink Floyd Album to Sell Over 10 Million Copies in the US

That would be The Dark Side of the Moon. Released in 1973, it didn’t just cross the 10 million mark in the United States—it eventually went 15x platinum, making it one of the best-selling albums of all time worldwide. Its unprecedented chart run (spending over 900 weeks on the Billboard 200) helped it quietly rack up those numbers while staying relevant for decades.

No other Pink Floyd album came close to that kind of U.S. sales volume at the time. The Wall later reached 11x platinum, but Dark Side got there first and kept going.
