American Top 40
(Classic) Charts
From its creation in
July 1970 through late November 1991, AT40 used the Hot 100 chart to
get its countdown. When Billboard changed the Hot 100 in November 1991,
AT40 switched charts to better reflect the music heard on its
affiliates. This chart was the "Top 40 Airplay" chart, whose name later
changed to "Hot 100 Airplay". However, this also did not sit well with
all affiliates, and AT40 finally switched to the "Top 40 / Mainstream"
chart. During the show's original run, 5363 songs made the top 40, and
there were 552 Number Ones. The first number one song was "Mama Told Me
Not to Come" by Three Dog Night, and the final number one song was "On
Bended Knee" by Boyz II Men. Below are samples of some important charts
in Classic AT40 history.

found in the new Radio and Records magazine.
