Chart-topping acts

Number-ones since 1890
This is a list of songs that have peaked at number-one in the United States since 1890.

All songs in Pop Hits appear in Pop Memories, though Pop Hits excludes many songs for the years 1940–1943, which otherwise appear only in Pop Memories. From the end of 1943 up through the end of 1954, both books show identical listings for all number-one hits, including chronology and total weeks, with the exception of some of the dates being shown as either earlier or later.

Billboard changed their date of issue from a Saturday to a Monday following the Saturday, April 27, 1957 chart, beginning with Monday, April 29, 1957 (which should have been Saturday, May 4, 1957), and ending Monday, December 25, 1961 (which should have been Saturday, December 30, 1961). To get the corrected Saturday date, five advanced days must be added on. Instead of an issue date of Monday, January 1, 1962, this was corrected and changed back to a Saturday date for the week-ending Saturday, January 6, 1962. All week totals at number-one are unchanged and remain the same. For consistency, all dates listed here have been re-adjusted accordingly to show all Saturday dates only.

Billboard began compiling their Hot 100 chart from data provided by BDS and SoundScan on November 30, 1991, the first major change of the chart's compilation since its inception in August 1958.

All Information for the years 1890–1954 is taken from the book Pop Memories, 1890–1954; for the years 1955–2010 from the book Top Pop Singles, 1955–2010; and since then, from Billboard's website.

Note
The following is a list of all 12 "date errors" which appear in Pop Memories.

Note on totals

 * In accordance with Billboard's policies on double A-side single releases, "Candle in the Wind 1997" / "Something About the Way You Look Tonight" by Elton John is counted as one single A-side release, not two, as each song is on the same individual side, one with the other. Elton John's total for number-one hits is thus 9, not 10. "Don't Be Cruel" / "Hound Dog" by Elvis Presley is counted as two separate releases as each song is on a different individual side (A-side and B-side), one from the other. Elvis Presley's total for number-one hits is thus 18, not 17.
