KMOX airs a talk radio format with blocks of news every morning and in weekday afternoon drive time. Middays it carries the nationally syndicated Rush Limbaugh Show with local talk hosts Charlie Brennan heard in late mornings and Mark Reardon in early afternoons. In the evening, the station airs sports. At night, local host Jon Grayson is heard, followed by two syndicated shows, "Our American Stories with Lee Habeeb" and "America in the Morning."
On weekend mornings, all-news blocks start the schedule, followed by programs on money, health, car repair, home improvement and old time radio dramas and comedies. Some weekend shows are paid brokered programming. KMOX is the flagship station of the St. Louis Cardinals Baseball team, and was the flagship station for the St. Louis Blues Hockey team through the 2018-2019 season.
KMOX has a large team of local newscasters and reporters, and airs CBS Radio News at the beginning of most hours. KMOX also has an agreement to share news gathering and weather information with KMOV, the CBS Network affiliate for St. Louis. At one time, KMOX and KMOV (formerly KMOX-TV) were sister stations, both owned by CBS.
KMOX was started in the early 1920s by a group of businessmen who formed a company known as "The Voice of St. Louis, Inc." According to the station's official website, the KMOX call sign was assigned by the Federal Radio Commission (a forerunner of the Federal Communications Commission). The station's owners wanted KVSL, for "Voice of St. Louis." The owners also applied for KMO, with MO the abbreviation for Missouri, but those call letters had been in use by another station since 1922, KMO (now KKMO) in Tacoma, Washington. KMOX signed on the air on December 24, 1925. The "X" was added because the starting date was Christmas Eve, or "X"mas Eve. A local legend states the call letters mean Kirkwood, Missouri On Xmas.
In 1927, the station gave prominent coverage to the Charles Lindbergh flight across the Atlantic, in his plane, The Spirit of St. Louis. That same year, KMOX became one of the first 16 stations in the CBS Radio Network. Two years later, CBS bought KMOX, and began the process of getting approval to build a 50,000-watt transmitter tower. When completed, it gave the now-clear-channel station a signal that could be heard at night through much of the U.S. In the early days of radio, KMOX broadcasts had been picked up in Scotland, New Zealand, the Arctic Circle and South Africa.
In 1933, KMOX covered the first post-Prohibition case of Budweiser beer leaving the Anheuser-Busch St. Louis brewery for the White House, a story carried nationally by CBS. Through the "Golden Age of Radio," KMOX carried the CBS schedule of dramas, comedies, news, sports, soap operas, game shows and big band broadcasts. The studios and offices were housed in the Merchandise Mart Building on Washington Street.
CBS had planned to have a corporate-owned and operated television station in St. Louis, to pair with KMOX 1120. In 1957, the network originally won an FCC construction permit to build a new station on Channel 11, the last remaining commercial VHF channel in St. Louis. But after being approached with an offer, CBS decided in August of that year to instead buy the existing KWK-TV for $4 million. KWK-TV was owned by a group including the publisher of the St. Louis Globe-Democrat.
CBS took control of Channel 4's operations that March, and changed its call letters to KMOX-TV, sharing the call sign with AM 1120. The original Viacom (not the current one) purchased Channel 4 from CBS in 1986, and because of an FCC law in place then that prohibited TV and radio stations in the same market, but with different ownership from sharing the same callsign, it subsequently amended its call sign to KMOV.
KMOX added an FM station on February 12, 1962. It broadcast at 103.3 MHz and mostly simulcast the AM station. By the late 1960s, KMOX-FM was separately programmed, airing an easy listening sound, later going to Top 40 as KHTR in 1982 and is currently classic hits KLOU, owned by iHeartMedia, Inc.
In July 1968, CBS opened a new studio and office facility in downtown St. Louis to house KMOX-AM-FM-TV, which until that point had been operating from separate locations. The radio stations had been headquartered near Forest Park. KMOX-TV moved from Cole Street into the new facility, known as One Memorial Drive, and remains there to the present day.
As network programming shifted from radio to television in the 1950s, KMOX scheduled a full service format of talk shows, news and middle of the road music. In 1955, Robert Hyland Jr. became KMOX's general manager, a role he held for nearly forty years. It was Hyland who leveraged KMOX's relationship with the Cardinals, signing many lucrative advertising contracts with local businesses.
Hyland made the decision in 1960 to eliminate the station's afternoon music programming, the last of the non-talk shows. That made KMOX the first full time talk radio station in the country, helping keep KMOX dominance in the St. Louis radio market for many decades. On February 29, 1960, Jack Buck hosted the first "At Your Service" program, which included an interview with former First Lady Eleanor Roosevelt. That program, like the sports and talk shows that soon followed, pioneered a format for radio featuring news maker interviews, guest appearances, and calls from listeners.
Karen Carroll was general manager from 1998 until 2003, when Tom Langmyer was promoted to the top position. Langmyer left in 2005 to become vice president/general manager of WGN Radio in Chicago. Dave Ervin managed the station from 2005 to 2008. Becky Domyan , who also oversees sister stations KEZK and KYKY is the station's current Market Manager & Sr. Vice President for Entercom.
On January 30, 2012, Jon Grayson's "Overnight America," based at KMOX, and also airing on CBS stations WCCO Minneapolis and KDKA Pittsburgh, became a nationally syndicated program with several dozen stations airing it across the country. The syndication was discontinued in 2017, but the show continues to air late nights on KMOX.
On February 2, 2017, CBS Radio announced it would merge with Entercom. The merger was approved on November 9, 2017, and was consummated on the 17th. The Entercom acquisition ended KMOX's 88 years of CBS ownership.
KMOX held the distinction of holding the record for consecutive number one Arbitron ratings books in the United States. The station was consistently the top rated radio station in St. Louis since the ratings service began in 1972 until 2010, when WARH took over the top spot in the Arbs. KMOX remains the top rated AM station, consistently in the top ten in the Nielsen ratings for St. Louis.
KMOX has carried the Rush Limbaugh show weekdays 11am-2pm for several decades. The program is sometimes pre-empted by St. Louis Cardinals' afternoon baseball games. Limbaugh is one of the few non-local shows broadcast on the station. It is syndicated by Premiere Networks, a subsidiary of iHeartMedia. KMOX also carries two non-local shows overnight, "Our American Stories with Lee Habeeb" and "America in the Morning." Habeeb is a programmer with the Salem Radio Network. America in the Morning is supplied by Westwood One, a subsidiary of Cumulus Media.
For the past 21 years, KMOX has hosted a holiday radio program, in which KMOX personalities perform an old-time radio show in front of a live audience.
During the 1930s and 1940s, KMOX was one of several St. Louis stations broadcasting both the Cardinals and St. Louis Browns baseball games. KMOX lost broadcasting rights in 1948 when a new Cardinals radio network was formed by the team, but by the 1950s, it became the flagship station of that network (in part due to its clear channel status).
KMOX's most famous sports broadcaster was Jack Buck, who was the station's year-round sports director during the years he was also calling baseball and football for the CBS radio and television networks. Another famous announcer was Harry Caray, who did play-by-play for Cardinals' baseball from 1945 through 1969. Bob Costas did play-by-play on KMOX for the Spirits of St. Louis of the American Basketball Association from 1974 until the ABA-NBA merger in June 1976.
At times, the station's emphasis had shifted away from broadcasting St. Louis professional sports teams. In 2000, the St. Louis Blues hockey team moved to KTRS after having been on KMOX for all but three of the team's 33 seasons (1967–2000), but the games returned starting in the 2006–07 season. The St. Louis Blues moved to WXOS starting in the 2019-2020 season. In 2006, the Cardinals' broadcasts moved to KTRS after 52 seasons on KMOX (1954–2005) after the team purchased controlling interest in KTRS. On September 1, 2010, the Cardinals announced the return of broadcasts to KMOX, starting in the 2011 baseball season. KMOX aired the University of Missouri Tigers Football and basketball games for many years. Starting in the Fall 2011, the Tigers moved their basketball, football, and news & talk programs to 550 KTRS.
The station continues to host sports programming such as "Sports Open Line," heard Monday through Friday nights, beginning at 6 p.m. Chris Hrabe is the main host. "Sports on a Sunday Morning" airs from 10 a.m. to noon on Sundays.
Notable current and past KMOX broadcasters include:

In the playoffs the Cardinals swept the San Diego Padres 3 games to 0 in the NLDS. However, the Cardinals lost to the Astros 4 games to 2 in the NLCS.
The season was the last one played in Busch Memorial Stadium by the Cardinals and they moved to the new Busch Stadium the next year. The Cardinals also moved their radio broadcasts from KMOX after a 55-year affiliation to KTRS after the season. After the 2010 season, the Cardinals would move their radio broadcasts from KTRS back to KMOX, starting in 2011.
First baseman Albert Pujols won the MVP Award this year, batting .330, with 41 home runs and 117 RBIs. Chris Carpenter won the Cy Young Award this year, with a 2.83 ERA, 21 wins, and 213 strikeouts.
