Originally signed on the air on December 5, 1954 as KVOO-TV, a primary NBC affiliate on VHF channel 2 and was first owned by Central Plains Enterprises, a 50/50 venture between Southwestern Sales Corporation and All-Oklahoma Broadcasting, the former was led by William G. Skelly, founder of Skelly Oil who also owned KVOO radio (1170 AM, now KFAQ).
On June 15, 1970, Central Plains Enterprises sold KVOO-TV to the Scripps–Howard Broadcasting subsidiary of the Cincinnati-based E. W. Scripps Company, for $6.6 million in cash plus $1.2 million worth of stock shares; the sale received FCC approval on November 25, 1970, and was finalized the following month on December 31.
Channel 2 changed its callsign to KTEW-TV on January 1, 1971 (standing for "Tulsa E.W. Scripps", and also easily interpreted as sounding like the phoneticism for "two"). This change was made due to an FCC rule in effect at the time that prohibited television and radio stations in the same market, but with different owners from sharing the same call letters.
The "2" logo used by the station until 1990 is similar in design (but not wholly the same) to that of fellow NBC affiliate WESH in Daytona Beach and Orlando during this time period.

The 1976 "2" survived KTEW-TV's callsign to KJRH, which took place on July 14, 1980. The change was made in honor of Jack R. Howard, who served as president of the E. W. Scripps Company and chairman of the Scripps–Howard Broadcasting subsidiary from January 1953 until his retirement from the company in December 1976 (the "TV" suffix was added to the callsign on February 10, 2010; the KTEW call letters are now used by a Retro Television Network-affiliated low-power station based in Ponca City).
