Pink Floyd's evergreen album The Dark Side of the Moon continues to hold the record, by far, for the most charted weeks on the Billboard 200: 917! The set, which was released in 1973 and spent a week at No. 1, continued to chart on a mostly regular basis through 1988.

After 1988, the set departed the tally, but returned in 2009 once the chart's rules were altered to allow older albums (generally referred to as "catalog albums") to rank on the weekly list. (Between May 1991 and December 2009, catalog albums were mostly barred from charting.)
