Features of the Kasem-era shows

During Kasem's run as host, the AT40 show had a number of popular and distinguishing features:
  • Bios & stories: Most segments of the show included two countdown songs. Often Kasem would introduce the second song in the segment with a "story" about the song and/or its recording artist (often teased

."

  • "Number" jingles: Occasionally a song would be preceded by a brief audio clip of a group of singers announcing the song's position on the chart (e.g. "Number 40!"). This was especially common for the first song played in each hour of the show, but was usually not done for the #1 song (which was usually introduced with a drum roll), or for songs preceded by a story. The "number" jingles were updated and re-recorded from time to time, and by the mid-1980s the show had begun using two sets of "number" jingles: the standard set, to be used with up-tempo songs; and a softer alternate set, usually used with low-key or romantic songs.
  • Chart trivia: AT40 also featured several question letters in each show, where a listener would write to ask a chart trivia question. Sometimes these letters led to an extra song being played, though this became less common as songs increased in length in the 1980s.
  • Long Distance Dedication: This feature had evolved from a spoken-word 45 single that Kasem had recorded in 1964, "Letter from Elaina". The LDD feature began with the August 26, 1978 broadcast, two months before the show expanded to four hours (the first LDD, located in the mail by staffer Matt Wilson, was "Desiree" by Neil Diamond

    , sent in by a man whose girlfriend, named Desiree, was moving to Germany to live with parents on an American air base). When that show was rebroadcast the weekend of August 25–26, 2007, Kasem recorded two optional segments (played at the discretion of the station) in which he did phone interviews with the man and his former girlfriend about the LDD. Most shows featured two long distance dedications; one would be taken care of during each half of the show. (Sometimes a song currently in the countdown would also be requested as a LDD; in such cases, Kasem would typically read the dedication first, and sometimes not even announce the song's chart status until after the song was played.) This feature endured on AT40 into Shadoe Stevens' run as host of the show, from 1988 to '95, 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. Long Distance Dedications were dropped from AT40 after Ryan Seacrest became host in 2004, but they continued as part of Kasem's adult contemporary countdowns.
  • Top Three recaps: Beginning the weekend of February 24–25, 1979, a recap of the previous week's top three songs started off each AT40 episode. Originally all three songs would actually be played before the countdown began in earnest, but when time constraints became an issue, Kasem would simply announce the #3 and #2 songs and play only the #1 song; or just announce all three songs before beginning the current week's countdown. By mid-1983, abbreviated recaps had become the norm.
  • Dropoffs: Generally during the first hour on most shows, Casey would announce songs that had left the top 40 that week.
    1. 1's on other Billboard charts: Casey would give a rundown on songs and albums that have made #1 on other Billboard charts, such as country, soul/R&B, and dance/disco. These would typically be announced during the Top 10, often before the #1 song on AT40.
  • Predicting next week's #1 song: For a time in 1972 and 1973, following the week's #1 song, Casey would try to predict what the #1 song would be on the following week's countdown, based on a poll of the AT40 staff. During the 46-week period that the predictions were used, the poll was successful only 22 weeks, and failures 24 weeks. The final song predicted, on the December 8, 1973 broadcast, was The Most Beautiful Girl

    "The Most Beautiful Girl" is a song recorded by Charlie Rich and written by Bill Sherrill, Norris Wilson, and Rory Michael Bourke.

    , which was #1 the next week.
  • Great Radio Stations: Once an hour, generally halfway into the hour, Casey would give a list of three or four radio stations that carry AT40, beginning each list with "American Top 40" is heard in the fifty states and around the world every week on great radio stations like.... Usually at least once a program, a foreign AT40 affiliate, or a mention of Armed Forces Radio

    , is given, usually as the last station in the list. In addition, new AT40 affiliates are mentioned at the top of one of the hours (never the first hour). The multiple station mentions became a regular feature in 1972; prior to then, only one station would be mentioned per hour. The first station mentioned on AT40 was KMEN (now KKDD

    , on the August 29, 1970 program.
  • Special Reports: Occasionally, Casey would do a special report on a particular subject involving the music industry, usually related to a particular song or artist on that week's countdown. For example, when Musical Youth

    Musical Youth are a British reggae band. The group originally formed in 1979 at Duddeston Manor School in Birmingham, UK.

     music.
  • Whatever happened to...: Casey would periodically do a segment giving an update on an artist who has not been on the charts for some time.
  • Oldies: During its first year, each AT40 show would feature 3 or 4 "oldies", or chart topping songs of the past. Normally, one old song would air per hour, which at the time mirrored the format of most Top 40 stations. Most of the oldies included were from the Rock 'N Roll era (post 1955). But occasionally, songs by pre-rock artists like Kay Starr, Perry Como or Nat King Cole would be included. Each song was heavily promoted by Casey and contained a story about the artist or some sort of fact making it relevant to the contemporary audience. By the fall of 1971, only 1 old song appeared per show. The following year, the "oldie" feature was dropped altogether. Oldies were brought back to AT40 in the fall of 1975 under the title "AT40 Extra". But the feature was phased out again by the end of 1976. Old songs would rarely appear again until the AT40 Archives feature began in 1978. Today, some classic rock stations airing re-runs of these early shows will edit some of the "oldies" features out of the broadcast, as songs from the 40s, 50s and 60s do not reflect the stations' mostly 70s and 80s music format.
  • AT40 Archives: Once the show expanded to four hours, each of the first three hours ended with the "AT40 Archives" segment that featured a number one song of the past. From October 1978 to June 1980 the number one songs of the 1970s were featured in the "AT40 Archives", and from June 1980 to November 1981 the number one songs of the 1960s were featured. The "AT40 Archives" feature was gone by the end of November 1981; for a short time in 1985, however, the show did feature a segment known as the "AT40 Hall of Fame" spotlighting a noteworthy artist (who may or may not have been charting that week).
  • Commercial bumpers: Many commercial breaks generally have a singing jingle at the start and end of the breaks. At the start of each break is generally the singers singing either "Casey's coast to coast" or "The hits from coast to coast"; both were used interchangeably. The end of the breaks are marked by the singers singing the name of the program, "American Top 40". The bumpers were originally designed so that stations with no local ads at that point could continue straight to the next segment, with the bumpers changing to a mere jingle: "Casey's coast to coast American Top 40".
  • Bumper music: The end of each hour's worth of programming would typically be indicated by an approximately one-minute-long piece of nondescript bumper music

    . For the first few years of the program, the bumper music was merely the AT40 theme, but beginning in 1978, different pieces began to be used. Like the "number" jingles and the AT40 theme music, this musical segment was occasionally updated and re-recorded, but its only distinguishing feature was the occasional use of the AT40 theme as a leitmotif

     before starting the next hour, and was also used by stations to "pad out" the show so that it would always end on time.
  • Sign-off: After the #1 song was played, the bumper music would begin playing, and over that, Kasem would typically give that week's chart date and read the end credits, then sign off with what would become his, and the show's, unofficial motto: "Keep your feet on the ground, and keep reaching for the stars." In the early years of the show, he usually added "and keep your radio tuned right where it is"; this phrase had returned to the show by the time the AT40 brand name was revived in the late 1990s (Kasem had used it also on "Casey's Top 40" and its Adult Contemporary-format spinoffs). Even his sign-off music became popular, as "Shuckatoom

    ) became a highly requested song, although it was never used apart from the show.


Although the show's format obviously implied an average of ten countdown songs per hour (once the show had gone to a four-hour format), this was not rigidly enforced; however, by the mid-1980s it had become increasingly rare for the final hour of the show to have any more than the top eleven or any fewer than the top nine songs left to play. The songs' run times determined how many would comfortably fit into each hour. The show bent to fit the Billboard rankings which, to many listeners, were sacred, and some songs had to be edited (in addition to whatever edits had been done for single release), with a verse and/or chorus chopped out, in order to fit into the show. But Casey and his producers never lost sight of the fact that the same music was being played on other stations everywhere, and that the stories behind the songs were the chief reason that listeners tuned to AT40.

1988-1995: Shadoe Stevens era

In 1988, Kasem left the show over contract concerns with ABC. Industry trade paper Billboard magazine reported that the main disputes between Kasem and Watermark/ABC were over his salary, because of declining ratings and a smaller group of stations airing the show. Casey's final AT40 show aired on August 6, 1988. At no point during that final show did Kasem ever let on that any changes were afoot, and simply omitted the phrase "join me next week" while closing the show.

Kasem was replaced by Shadoe Stevens

In an attempt to win back an audience, AT40 tried new show features, including interview clips, music news, top 5 flashbacks, and previews of upcoming chart hits (called the "AT40 Sneek Peek"). AT40 in its later Shadoe years frequently used a "No Nuttin'" gimmick, in which the number jingle was followed by the song, with no introduction by Shadoe; this tactic irked critics of the show.

The resurrected American Top 40 kept the Radio and Records CHR/Pop chart previously used for "Casey's Top 40" and was used as the basis for the show for the majority of this period. The only exception was a brief period from October 2000 to August 2001 when an obscure Mediabase

With the host change, AT40 underwent a makeover, using a new theme song and introducing several new features. These extras included interviews with celebrities (which were not restricted to musical or countdown artists), a gossip section, and an update on movies screening in cinemas. Other extras inducted on a regular basis include "AT40 Breakout", a song predicted to crack the chart within the next few weeks (formerly known as the "Out of The Box" hit); "Request Line", a segment in which Ryan Seacrest will play a song requested by a listener; "Double Play", a former hit from the artist just played; "AT40 Sleaze" (inspired by the "Dees Sleaze" segment of the Rick Dees

 Weekly Top 40 radio show); and "AT40 Rewind", a hit song from the past decade or so. In between songs, Seacrest and his guest hosts often make deadpan one-liners while writers and producers can be heard laughing frequently, including the security guard "Roger". Additionally, Seacrest initially opened most shows by playing the previous week's #1 song, as Kasem often did in the 1980s; this was discontinued after 2006, but in mid-2009 Seacrest began including a shorter recap segment in the show's introduction, in which he would play brief segments of the previous week's top three hits.

The show also began using a new chart that used no recurrent rule. On the first show with Ryan Seacrest, this led to several older songs reappearing after having dropped off many weeks earlier. Over the long term, it meant songs could spend long runs for about a year on the chart even after they went to recurrent status on other published charts. "Here Without You

, ran a series of American Top 40 episodes from the 1970s. Aside from one week, when the station attempted to air a four-hour episode from 1979 in the three-hour timeslot (resulting in the show getting cut off at #11 and the top 10 not being heard), this test run was largely successful. Because of the success, Premiere Radio Networks decided to launch "Casey Kasem's American Top 40: The 1970s" into national syndication featuring the three hour shows from 1970 to 1978, and the last three hours of shows originally aired from October 1978 through December 1979. (One original four-hour program, first aired in October 1978, was edited into a three-hour program for reairing in 2007, and the four-hour "Disco Hits" special from July 1979 with the first hour optional was aired in 2008, but until the fall of 2010, no other program from the last 15 months of the 1970s was included in the "AT40: The 70s" package.)

The 1980s version premiered on April 8, 2007, replacing the American Top 40 Flashback reruns. The shows are available in either their full original four hour format, or an abbreviated three-hour version that omits the first hour of the show. To date, the latest program to air as part of the "AT40: The 80s" package has been August 6, 1988—Kasem's last show with the original program.

In March 2008, XM Satellite Radio rebranded the XM broadcasts with the "Casey Kasem's American Top 40" name and logo used for terrestrial broadcasts, although XM still aired the commercial-free broadcasts, while Premiere Radio carries edited and recut broadcasts with commercials. Following the merger of Sirius and XM, the AT40 shows airing on those platforms have occasionally been edited. In some cases, extras and LDDs have been cut from the original broadcasts.

 singles chart from the show's inception in 1970 to November 23, 1991. The chart was widely regarded as the industry standard in tracking the most popular songs in the country, and was thus a natural choice to be used. While using these charts worked well for the first half of the 1970s, as music changed during the decade, and disco became popular on the charts, some rock stations began to drop the show because of complaints from program directors that AT40 was "playing too many songs not on their playlist."

This gradually became a wide schism as rock splintered into a half-dozen formats in the early 1980s. Historians have noted that no one station actually played all of the songs on the Billboard Hot 100

 list, because they represented overlapping formats—hard rock, mainstream rock, heavy metal, dance, new wave, punk, rap, pop, easy listening/adult contemporary, country, and so on. Stations tended to specialize in only one or two of these formats, and completely ignore the others. As a result, AT40s weekly playlist could be very diverse in the styles and formats of the songs played.

One solution for the AT40 producers was to air frequent specials (at least three or four times a year) that concentrated on the classic music of the past, such as Rock in the Movies, Top Hits of the Seventies, and so on. But as Top 40 stations evolved into CHR

, which entered at #2.

In January 1993,
American Top 40 switched charts again, this time to the Billboard Top 40 Mainstream chart. This chart had more Top 40 Mainstream hits but fewer urban/dance/rap songs.

AT40 did not always use the official year-end chart from Billboard during the 25 years that they used their charts. In 1972 and 1973; in 1977; from 1980 to 1984; and again from 1990 to 1994, AT40 compiled its own year-end chart. These charts were very close to Billboard's, but AT40 would go with a mid-December to early-December time period where Billboard's survey year varied from year to year. AT40 matched Billboard's number one song of the year every time except in 1977, 1984, 1990 and 1993.

Radio & Records magazine

With the show's revival in 1998, a new chart was implemented, the top 40 portion of Radio and Records CHR/Pop top 50 chart, which was already in use on Casey's Top 40. This would also be a first time a recurrent rule

 was used on the show, albeit indirectly. Songs that were below #25 and had exceeded 26 weeks in the top 50 were removed, and these removals, if they occurred in the top 40, would be reflected on the appropriate week's program. In 1999, the rule was modified to further restrict long chart runs. Songs falling below #20 with at least 20 weeks in the top 50 would now be removed.

On October 21, 2000 American Top 40 began using an unpublished chart on a weekly basis for the first time in its history. The chart seemed to be a variant of the CHR/Pop chart provided by Mediabase
Mediabase

Mediabase publishes music charts and data based on the most played songs on terrestrial and satellite radio, and provides in-depth analytical tools for radio and record industry professionals...

, the data provider to
Radio & Records. The most noticeable feature of this new chart was its ambiguous recurrent rule. Songs would be removed regularly from within the top 15, seemingly regardless of the number of weeks it had spent on the chart. This chart lasted until August 11, 2001, when AT40 returned to the Radio & Records Pop chart. The return coincided with another modification in the recurrent rule; songs would be removed below #25 after 3 consecutive weeks without a bullet (an increase in radio plays). This change would be short-lived, and in November 2001, Radio & Records returned to the 20 weeks/below #20 rule, which remained in place for the remainder of Kasem's tenure.

Adult Contemporary countdowns (AT20 and AT10)

Beginning in the early 1990s, Casey Kasem also hosted two other shows counting down the top adult contemporary hits of the week. He continued to host both shows even after Ryan Seacrest took over the reins of
American Top 40.

Kasem's countdown for Mainstream and Soft Adult Contemporary radio stations debuted in 1992 under the name
Casey's Countdown. Originally Casey's Countdown consisted of 25 songs, but in 1994 it was shortened to 20. With the revival of the AT40 brand name, the AC chart became American Top 20. In March 2004, the Mainstream AC edition was shortened again, this time from twenty to ten songs, and became known as American Top 10.

Another show for Hot Adult Contemporary radio stations debuted in November 1994, since the Hot AC or "Adult Top 40" format was rapidly growing in popularity at the time. The original name of the show was
Casey's Hot 20. Like its sister Mainstream AC show, it, too, was renamed American Top 20 once AT40 was relaunched (resulting in two different shows being entitled "American Top 20").

Originally both AC shows were three hours in length and included many
AT40 staple features, including chart "extras" and Long Distance Dedications (known as "Requests and Dedications" during the Westwood One years), as well as spotlight features on number one hits of each chart week from years past. AT10 continued to feature Long Distance Dedications, and some additional features that were staples on the original AT40 were re-added to both shows over the last several years, including the "Book of Records" and "Whatever Happened To...?" AT10 also featured additional chart extras under the banner of "AT10 Spotlight," built around a particular theme (the theme for the first week of the revamped AT10 in 2004 was "Band Members Gone Solo").

As with the Top 40 show, both
Casey's Countdown/AT20/10 AC and Casey's Hot 20/AT20 Hot AC initially used the AC charts published by Radio & Records from their inception until 2003, except for a brief period in 2000-2001 when both used unpublished Mediabase 24/7 charts. From 2003 to August 2006 (when R&R stopped using Mediabase to compile its charts), both shows used the Mediabase charts. From August 2006 until the end of its run, the AC shows once again were based on unpublished charts.

The American Top 40 format was adapted in an Australian show titled
Take 40 Australia, similarly counting down the top 40 songs in the country.

Censorship, offensive songs and affiliate standards

American Top 40 airs radio edits for American radio stations, no matter what the country it airs in.

Casey Kasem and Watermark's policy regarding putting
American Top 40 together was to always play the 40 most popular songs in the United States and never to ban a record from the countdown. However, whenever songs with potentially offensive lyrical content made the top 40, Watermark would send out memos to affiliated stations alerting them of the presence of that song in the countdown and sometimes provide stations with suggestions on how to edit the song out of their AT40 broadcasts. The first song to receive this advisory was in April and May 1971, with a spoken word piece, "The Battle Hymn of Lt. Calley

Another example of this policy dates from 1978, when Billy Joel's "Only the Good Die Young
Only The Good Die Young
"Only the Good Die Young" is a song from Billy Joel's 1977 pop rock album, The Stranger. The song was controversial for its time, with the lyrics describing a boy who tries to convince a Catholic girl who is a virgin to have sex with him....

" was on the charts. Because of the nature of the song (Joel singing about urging pre-marital sex by a teen Catholic girl, Virginia), AT40 had placed warnings in shipments to warn affiliates in highly Catholic populated areas along with a special break in the countdown for stations to substitute another song in its place. The affiliates usually used the suggestion, though some did not and no major complaints were ever heard. Many of these memos have been reprinted in Pete Battistini's book, "American Top 40 with Casey Kasem (The 1970s)."

Although Kasem and his crew never banned a song from airplay on the countdown, there was at least one instance in which Kasem refused to announce the title of a song on his show. When George Michael

Also, as had been done with previous controversial hits, because of the song's suggestiveness, the show's structure was altered slightly, so stations could opt out of the song. This pattern was also evident during the 1987 Year End countdown. The song title was mentioned five times during its chart run (6/20/1987; 6/27/1987; 7/4/1987; 9/12/1987 and 9/19/1987), during the week-ending episode of September 26, 1987, when it dropped out of the Top 40, and during the Top 100 of 1987 show; Shadoe Stevens, his successor, however did mention the title on the show from July 31, 1993 as part of the Flashback feature, as it was in the top 5 from that week in 1987.

" by The Digital Underground, and "Tic Tac Toe" by Kyper.

As has been mentioned previously, many rock radio stations in the late 1970s adopted anti-disco stances, and this, too, was reflected in the way some affiliates edited AT40. For example, one 1979 show featured a story about disco saving New York; again, the show was structured so that anti-disco stations could edit the story out of the show. (Notably, Kasem ended the monologue with the prediction that "disco is here to stay," which was proven false in short order, as disco rapidly fell out of fashion by 1980.)

 handling the hosting duties for Casey Kasem. The special Cleveland-only
American Top 40 episode did not feature the AT40 Archives, extras, or Long Distance Dedications — just the top 40 singles of that week, which was preceded by a recap of the previous week's top three. Most of the songs played were longer album versions or 12-inch extended versions. Through clever editing, Coleman also took the "Casey's Coast to Coast" jingle and spliced in a "T," to provide an appropriate "TC's Coast to Coast" jingle. Kasem did not learn about the deception until 1996, laughing the whole thing off by saying, "Maybe I don't want to hear it!"

Coleman's sleight-of-hand was actually the
second time a version of the AT40 had aired that was not quite on the up and up. According to Rob Durkee's book "American Top 40: The Countdown of the Century", Dave Morgan of WDHF (now WNUA

Billboards list and merely played the records, apparently heavily implying (but not actually identifying) the show as American Top 40. "My program director made me do it!" Morgan said years later.

Additionally, the top songs of the year were counted down at the end of every year. In 1970 & 1972, AT40 counted down the year's top 80 hits. In 1971 & 1973, they only counted down the top 40 because of their top 40 Christmas

It is a Christian feast that commemorates the birth of Jesus Christ, liturgically closing the Advent season and initiating the season of Christmastide, which lasts twelve days...

 Countdowns those two years. Beginning in 1974, the top 100 songs of the year were counted down and was done so every year with few exceptions. In 1979, they did the top 50 songs of that year and followed it with the top 50 songs of the 1970s. This was done again in 1999, except only the top 40 of the year and decade were aired. In 2009, the year-end countdown took place as usual (two weeks long, with the top 100 songs of the year being counted down), but on the first week of 2010, the top 40 songs of the decade were counted down. The year-end shows were counted down over a two week period (although stations could edit the shows into one long show) until 1983, when the year-end show ran just one week for eight hours. In 1992, the year end countdown was temporary back to its two-week format, in 1994 (the last year of the old AT40) the year end countdown was only 50, and with the AT40 return in 1998 the year end countdowns were the 2 week format (except for 1999 when it was 50).

During the run of "American Top 20" and "American Top 10," an updated Christmas countdown, the "Top 60 Christmas Songs," would air annually the two weeks immediately preceding Christmas.
