Billboard Hot 100 chart achievements
This list highlights significant milestones
and achievements based upon Billboard
magazine’s singles charts, most notably
the Billboard Hot 100.
This list spans from the issue dated Janu-
ary 1, 1955 to the present. The Billboard Hot
100 began with the issue dated August 9,
1958, and is currently the standard music
popularity chart in the United States.
Prior to its creation, Billboard published
four singles charts: "Best Sellers in Stores",
"Most Played by Jockeys", "Most Played in
Jukeboxes" and "The Top 100" (an early ver-
sion of the Hot 100). These charts, which
ranged from 20 to 100 slots, were phased out
at different times during 1957 and 1958.
Though technically not part of the "Hot 100"
chart history, their data is included by Bill-
board for computational purposes, and to
avoid unenlightening discrepancies
"Buddy Holly’s debut single in the Top 40
was released posthumously" or "Elvis Presley
has seven Hot 100 number-ones").
There are chart discrepancies. In a prom-
inent example of the magazine’s retroactive
methodology, Elvis Presley’s
Cruel"/"Hound Dog" single is credited with
an 11-week run atop the Billboard chart in
the double-sided release
topped the "Best Sellers in Stores" and "Most
Played in Jukeboxes" lists for that length of
time (though the specific weeks differed).
Presley’s run lasted just eight weeks atop the
"Most Played by Jockeys" chart, and seven
weeks in "The Top 100"’s number one slot,
but artists are credited with their most favor-
able placements on any of the four charts.
This is why Billboard and its official statisti-
cian Joel Whitburn lists 17 number one
singles, for a total of 71 weeks, in 1956.
However, Billboard and Whitburn are not
in complete statistical agreement. Originally,
each side of the aforementioned Presley
single had a separate turn topping the sales
chart, with the titles "flipping" during its
11-week run. The Best Sellers in Stores chart
specified that in the case of such double
