First Pink Floyd Album to Hit No. 1 on US Billboard 200

The first Pink Floyd album to top the US Billboard 200 was The Dark Side of the Moon, which reached the peak position in 1973. Despite its massive long-term sales—it stayed on the chart for over 900 weeks—its actual time at No. 1 was surprisingly short: just one week in April 1973. That single week made history, launching the band into American mainstream success after years of cult following in the UK.
