The show began on July 4, 1970. Hosted by Casey Kasem, the show began as a three-hour program which counted down the top 40 songs on Billboard's Hot 100 Singles chart. Although the success of the show was uncertain, the show quickly gained in popularity. It expanded to a four-hour program on October 7, 1978, and by the early 1980s, the show could be heard on more than 500 stations in the United States alone.

Based on the success of American Top 40, Kasem and Don Bustany created the spinoff "American Country Countdown", a Top 40 country countdown patterned after Kasem's program. "ACC" (as the show is referred to by fans) premiered in 1973, and has been hosted since 1978 by radio personality Bob Kingsley.

In 1988, Kasem left the show due to contract concerns. His last show aired on August 6, 1988. Kasem was replaced by Shadoe Stevens, whose first American Top 40 show aired on August 13, 1988. Kasem went on to join the Westwood One radio network and start a rival show, Casey's Top 40, less than a year later. Many listeners were upset by Kasem's departure and, as a result, many stations dropped American Top 40 in favor of Casey's Top 40 once it hit the airwaves in early 1989.

During Kasem's run as host of the show, there were several features. The most famous was the Long Distance Dedication, which had evolved from a song that Kasem had recorded in the mid 60s. The Long Distance Dedication feature began when the show expanded to 4 hours in 1978. Most shows featured 2 LDDs. This feature endured on AT40 into Shadoe Stevens' run as host of the show and has also followed Casey (first as the "Request and Dedication") on his Westwood One shows and then back as the LDD when he returned to AT40 in 1998. AT40 also featured several question letters a show, where a listener would write asking a chart trivia question. Sometimes these letters led to an extra being played, though this became less common as songs got longer in the 1980s. Finally, each show would often have "stretch" stories, which were stories told before playing a song that sometimes barely related to the song itself.

As the show started to lose stations once Shadoe Stevens took over, several other features were tried, including interview clips and previews of upcoming chart hits. Despite these efforts, American Top 40 was cancelled on January 28, 1995.

American Top 40 was revived on March 28, 1998 when Casey Kasem again was involved in a dispute. As the rights to the "American Top 40" name reverted back to Kasem, he pitched the idea to Westwood One to rename "Casey's Top 40" to the AT40 name. Westwood One refused him this, and as a result, Casey took himself and the AT40 name to AM/FM Radio syndication (which dissolved into Premeire Radio Networks in 1999). In addition, two American Top 20 shows were created; one based on the Hot Adult Contemporary format and the other based on the Adult Contemporary format, both hosted by Kasem. As a result, Westwood One, still committed to do one more show after Kasem left, plopped in a fill-in host and simply called their final show "The Top 40".

On January 10, 2004, Ryan Seacrest took over the hosting duties of American Top 40 from Kasem, although Kasem would continue to host American Top 20 and American Top 10. Around this time, American Top 40 became more interactive, involving online song voting and e-mails being read on-air.
