"The Dark Side of the Moon" became one of the best-selling albums of all time. It is in the top 25 of a list of best selling albums in the United States. It held the number one spot in the US for only a week. But, it remained in the "Billboard" album chart for a total of 778 weeks (nearly 14 years). This is the longest any album has spent on the "Billboard" charts. The album came back on the "Billboard" charts when the Top Pop Catalog Albums chart was introduced in May 1991. It has stayed there since then. In the UK it is the sixth-best-selling album of all time.
