Originally signed on the air on July 2, 1954, as KGEO-TV, a primary ABC affiliate on VHF channel 5.
In 1958, KGEO moved from Enid to Oklahoma City, and became the ABC affiliate for the Oklahoma City area, taking the market's ABC affiliation from WKY-TV (channel 4), which replaced KTVQ (channel 25, channel allocation now occupied by KOKH-TV) as the city's ABC station when it signed off the air in 1956.

In November 1969, Cimarron Television announced that it would sell KOCO-TV to the Phoenix, Arizona-based Combined Communications Corporation (CCC) for $6.5 million. It was the first broadcast property ever acquired by CCC, which was formed earlier that year through the merger of the KTAR Broadcasting Company (owner of company flagships KTAR-AM-TV in Phoenix) and Eller Outdoor Advertising (a company founded by CCC president Karl Eller). The sale received FCC approval on July 17, 1970.
In February 1977, KOCO adopted "5 Alive" as its on-air branding, as part of Combined Communications' rollout of the "Alive" branding concept—which Peters Productions initially developed for Tribune Broadcasting-owned independent station WPIX (now a CW affiliate) in New York City in early 1976—on most of the group's television stations. Combined Communications would later be acquired by the Gannett Company for $370 million on June 7, 1979.

On November 20, 1996, Gannett announced that it would sell KOCO-TV to San Antonio-based Argyle Television Holdings II (the successor company to the original Argyle Television, which sold most of its television stations to New World Communications in May 1994) for $20 million, in exchange for fellow ABC affiliate WZZM in Grand Rapids, Michigan and NBC affiliate WGRZ in Buffalo, New York. The acquisition marked Hearst's return to the Oklahoma City market; the company owned radio station KOMA (1520 AM, now KOKC) from 1932 until 1938, when Hearst sold that station to John T. Griffin (who founded KWTV in 1953).
