''American Country Countdown'' is a weekly, [[LongRunner long-running]] syndicated radio program, currently hosted by Kix Brooks (of the country music duo BrooksAndDunn), which counts down the 40 most popular radio songs in the United States.

The show's history dates to October 6, 1973, and was conceived as a spinoff of ''AmericanTop40''. Both programs were created by Don Bustany, Tom Rounds and Los Angeles radio personality (and {{voice actor|s}}) CaseyKasem. Initially, Don Bowman – a Lubbock, Texas, native who became famous for his comedy recordings and association with Waylon Jennings and Willie Nelson – was the host. While he did a very credible job, conflicts with his touring schedule eventually forced him to give up the show in the spring of 1978. Bob Kingsley, who began producing the program in the spring of 1974, took over as host, and the rest was history.

The Kingsley era was arguably the height of the program, with his shows very much similar to Kasem's programs, in both hosting style and features: the occassional oldie or album cut, and stories about each of the songs. ''[=ACC=]'' – as the show is sometimes known – was initially three hours (just like ''[=AT40=]'' in its early years), and expanded to four effective with the January 18, 1986, show.

Like ''[=AT40=]'', ''[=ACC=]'' plays requests and dedications from listeners, today called "''[=ACC=]'' Inbox". Much like Kasem's "Long Distance Dedication," the requests were often sentimental in nature and directed at someone whom the listener had not seen in some time, or an anniversary of a landmark event (such as an anniversary or a relative's death).

Kingsley hosted ''[=ACC=]'' until 2005, when he was forced out after ABC Radio Networks – which owns the program – wanted to revamp the show; the announcement was made in October, and Kingsley's last program was December 24, the last regular countdown program of 2005. Kingsley started a rival program, ''Radio/BobKingsleysCountryTop40'', while ''[=ACC=]'' tapped Brooks as its new host. After several weeks of substitute hosts, Brooks took over on January 21, 2006.

Like ''[=AT40=]'', song-ranking data originally came from ''Magazine/{{Billboard}}'' magazine, only this time using the Hot Country Singles (now Hot Country Songs) chart. The show has used Mediabase as its chart source since August 2009. The show's chart length was trimmed to 30 songs effective February 12, 2011. Kix has also ditched the retro songs in favor of more recent recurrents.

!!''American Country Countdown'' provides examples of:
* EarlyInstallmentWeirdness:
** Pertaining to the Don Bowman years:
*** Early shows had him cracking jokes that today would be considered politically incorrect, if not downright offensive. (For instance, one of the very first shows from the fall of 1973 had him make the joke: "How do you make a horse quit complaining in the wintertime? Shoot him in the summertime!") In fact, one episode from April 1974 had him read a letter on-air from a fan who said he appreciated hearing the songs and countdown but thought the jokes were a little much; Bowman cooled it after that, and having Bob Kingsley begin producing the show around that time also helped keep his humor under control.
*** One of the early outro commercial bumpers featured the chorus singing, "Sweet talking', wise crackin' good timing' Don Bowman" along with a country artist of the day delivering in spoken word the "My kind of country, my kind of music" hook line. These were done by Bobby Bare, Tom T. Hall and Jerry Reed.
** Early 4-hour shows from 1986:
*** To fill in the time, a larger number of extras was played, usually by an artist who had a song debuting on the chart at least two years earlier.
*** The "ACC Calendar" was a semi-regular feature that was played at no set point in the countdown. This wasn't set until 1996, when it became the end-of-the-third hour feature.
** Early Kix Brooks shows:
*** Also featured a large number of extras, often a song that Kix himself wrote. Included on one of the first shows from January 2006 was Brooks' first No. 1 as a songwriter, "I'm Only In It For the Love" by John Conlee.
* TheEighties and TheNineties: When the show was arguably at the height of its power, although it actually started in TheSeventies and is still doing well today.
* GuestHost: Late in his tenure, Kingsley would often take one or two weeks off per year and hand the mic over to someone else (usually a DJ at a major market radio station). Incidentally, Kingsley was a guest host about a half dozen times during the Don Bowman era of the mid-1970s, usually when Bowman's touring schedule didn't allow him to make the trip to Los Angeles to record the program; other top country acts of the day – including Red Stegall – hosted ''[=ACC=]'''s special programs during the 1970s. Today, Donna Britt, executive producer of ''[=ACC=]'', handles the guest duties when Brooks is absent.
* LaserGuidedKarma: Kix's decision to cut the show to 30 spaces meant that he never got to hear his post-Brooks & Dunn single "New to This Town" on his own countdown, as it peaked at #31.
* LongList[=/=]TopTenList: Thirty songs (originally 40), plus a couple of extras, in four hours (originally three).
* LongRunner: The program debuted in 1973 and has been going strong ever since.
* {{Montages}}: A staple of the year-end programs from 1973-2005; this was simply the No. 1 songs during the past year, often in chronological order. The host – Bowman or Kingsley – would tease that somewhere included was the No. 1 song of the year. The montage was played between the Nos. 2 and 1 songs.
** Through the Kingsley years, as part of a stretch story, he would sometimes assemble a montage of songs related to an artist or theme, or having a common subject in the title (such as songs about money). These montages typically ran 2-3 minutes and had often about a dozen songs or so included.
* NothingButHits: The entire premise of the program. Anyone who has been fortunate enough to obtain vintage copies of past programs – especially those from early in the run – would hear hit songs of their day that have likely not been played anywhere for 30-plus years.
* QuietlyPerformingSisterShow: Of the parent program, ''[=AT40=]''.
* PreviouslyOn: Starting in 1986, the No. 1 song from the previously week's show would [[OpeningNarration lead off the countdown]]. This segment, which continued throughout most of the rest of Bob Kingsley's tenure as host, was inspired by sister program [=AT40=], which had played back the No. 1 song from the last program (and at times, Nos. 2 and 3 as well) to begin each week's show starting in 1979.
** Today, a "Top 3 Recap" begins each program, with Kix Brooks playing clips from the songs within that part of the chart.
* RearrangeTheSong: Like ''[=AT40=]'', single edits were usually used ... and when time was running short, some of those songs would be butchered even further.
** Oddly, a couple songs late in the Kingsley era seemed to ''always'' be presented in abridged fashion even though they weren't that long of a song to begin with.
* SpinOff: ''[=ACC=]'' is the country version of ''[=AT40=]''.
