Dark Side of the Moon is listed in the Guinness Book of World Records for being on the charts longer than any other album in history. Namely 591 consecutive weeks or 11.4 years in Billboard Top 200. A total of approx. 14 years (741 weeks) in and back in the top 200.

The album is one of the best selling albums of all time, (not counting compilations and various artists soundtracks), and within the top 25 best selling albums in the United States. Though it held the No. 1 spot in the USA for only one week, after 741 weeks it left the Billboard 200. The album was removed only by a rule change after 23 April 1988.
To this day, it occupies a prominent spot on Billboard's Pop Catalogue Chart and reached number one when the 2003 hybrid CD/SACD edition was released and sold 800,000 copies in the U.S. alone. On the week of 5 May 2006 The Dark Side of the Moon achieved a combined total of 1,500 weeks on the Billboard 200 and Pop Catalogue charts.

By 2006 worldwide sales of the album totaled over forty million. Between 8,000–9,000 copies are sold per week, and a total of 400,000 in the year of 2002, making it the 200th best-selling album of that year nearly three decades after its initial release. It is estimated that one in every fourteen people in the U.S. under the age of fifty owns or owned a copy of this album. According to an 2 August 2006 Wall Street Journal article, although the album was released in 1973, it has sold 7.7 million copies since 1991 in the U.S. alone and continues to log 9,600 sales per week domestically.

The LP was released before platinum awards were introduced by the RIAA on 1 January 1976, and it initially only received a gold disc. However, after the introduction of the album on CD, The Dark Side of the Moon would eventually be certified platinum in 1990. On 6 April 1998, the RIAA certified the album at 15x platinum, denoting sales of fifteen million in the United States alone - making it their biggest-selling album there.

The original title for the album was ECLIPSE (A Piece For Assorted Lunatics).
The album was recorded at Abbey Road Studios, London.
