"The Dark Side of the Moon" became one of the best-selling albums of all time and is in the top 25 of a list of best-selling albums in the United States. Although it held the number one spot in the US for only a week, it remained in the "Billboard" album chart for 736 weeks from 1973 to 1988. The album re-appeared on the "Billboard" charts with the introduction of the Top Pop Catalog Albums chart in May 1991, and has been a perennial feature since then. In the UK, it is the seventh-best-selling album of all time and the highest selling album never to reach number one.
