KOAM-TV first signed on at 5:22 p.m. on December 13, 1953, under the ownership of MidContinent Broadcasting Company, a joint venture of
The Joplin Globe newspaper and E. Victor Baxter and
Lester E. Cox, owners of KOAM radio (860 AM, the current
KKOW), with Baxter and Cox holding a controlling interest. The
Globe would eventually sell its minority stake in the station to Baxter and Cox. KOAM-TV launched as a primary affiliate of
NBC, owing to KOAM radio's long affiliation with NBC Radio, though it also had secondary affiliations with CBS (until
KSWM-TV launched in 1954),
DuMont (until that network's 1956 closure) and
ABC (until January 1968, when KODE became a full-time ABC affiliate and KUHI-TV signed on with CBS). On September 5, 1982, KOAM swapped affiliations with KTVJ (the former KUHI-TV and now known as
KSNF) and became a CBS affiliate. Mid-Continent Broadcasting sold the station to
Draper Communications, who also owned
WBOC-TV in
Salisbury, Maryland, in 1984. Draper then sold it to KOAM Ltd. Partnership in 1987. KOAM's digital signal on channel 13 signed on in 2001 and remained until KOAM turned off its analog signal at 12:38 a.m. on February 17, 2009 (the original date on which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate, which was later pushed back to June 12, 2009), following
The Late Late Show with Craig Ferguson, at which time KOAM ceased analog broadcasting and its digital broadcast returned to channel 7. Sister station
KFJX, the market's
Fox affiliate, moved onto KOAM's former digital channel 13 (KFJX continued to broadcast on analog channel 14 until May 2009 when a line of severe
thunderstorms damaged the broadcast tower, forcing the removal of the antenna). KFJX's signal is simulcast in
high definition on KOAM's digital subchannel 7.2. In June 2010, the DirecTV satellite system added Joplin locals to its channel lineup. Initially, KOAM and sister station KFJX refused to allow DirecTV to carry their stations. In February 2012, KOAM and KFJX began airing on DirecTV. On May 10, 2017,
Morgan Murphy Media announced that it would acquire Saga Communications' television clusters in Joplin, Missouri, including KOAM-TV, and
Victoria, Texas, including
KAVU-TV. The sale was completed on September 1. In
2024, KOAM parent company Morgan Murphy Media reached an agreement to broadcast eight
Oklahoma City Thunder games. Games aired on KOAM-TV or sister stations KFJX and KFJX-DT3. ==News operation==
