WKOI-TV (channel 43) is atelevision station licensed toRichmond, Indiana, United States, broadcasting theIon Television network to theDayton, Ohio, area. The station isowned and operated by theIon Media subsidiary of theE. W. Scripps Company. Transmission facilities are provided by unrelatedNBC affiliateWDTN (channel 2), which shares its digital channel with WKOI-TV through achannel sharing agreement, along with WDTN's sister station,WBDT (channel 26), ade facto O&O ofThe CW; the transmitter is located on Frytown Road in southwest Dayton. For regulatory purposes, WKOI's "main studio" facility is located atScripps Center in downtownCincinnati (along with many other Ion stations).

WKOI-TV signed on May 11, 1982, as anindependent station airingreligious programming. In 1986, it was purchased by theTrinity Broadcasting Network (TBN). As a TBN O&O, the station cleared almost all of the network's programming, only breaking away from the network once a week for local communitypublic affairs programming.

Until June 7, 2018,^[4][5] WKOI-TV's transmitter was located onSR 73 inMilford Township,Butler County, Ohio, nearCollinsville, approximately halfway between Richmond and Cincinnati. It thus served as the TBN station forNorthern Kentucky,East Central Indiana and a large swath of southwestern Ohio (Greater Cincinnati and theMiami Valley). Even though its transmitter was based within the Cincinnatitelevision market, its city of license, Richmond, is in the Dayton market. Thus,Nielsen counted the station as part of the Dayton market.

TBN entered into an option agreement with Ion Media on November 14, 2017, which gave Ion the option to acquire the licenses of WKOI-TV and three other TBN stations that had sold their spectrum in theFederal Communications Commission (FCC)'s incentive auction; Ion exercised the option on May 24, 2018.^[6] The sale was completed on September 25, 2018.^[7]

WKOI-TV (along with all other TBN-owned full-power stations) shut down its analog signal, overUHF channel 43, on April 16, 2009.^[9] The station's digital signal remained on its pre-transition UHF channel 39,^[10] usingvirtual channel 43. The station's signal wasmultiplexed, carrying TBN on 43.1, The Church Channel on 43.2, JCTV on 43.3,Enlace on 43.4 andSmile of a Child on 43.5. Later, The Church Channel becameHillsong Channel, JCTV becameJUCE TV and was combined on 43.3 with Smile, andTBN Salsa was added on 43.5.

On April 14, 2017, it was reported that WKOI-TV's over-the-air spectrum had been sold in the FCC'sspectrum reallocation auction, fetching just over $20 million, with the station expected to go off the air.^[11] On March 22, 2018, it was announced that WKOI-TV would share spectrum with unrelated NBC affiliate WDTN.^[1]

On June 7, 2018, WKOI-TV began sharing WDTN's digital channel, with all TBN channels dropped, andIon Television programming appearing on virtual channel 43.1.^[4] WDTN also continued to carry Ion Television on virtual channel 2.3, as it had since February 1, 2018; on June 29, 2018, when WDTN's sister station WBDT also began sharing WDTN's digital signal, virtual channel 2.3 was dropped.

WKOI-TV's programming was previouslyrelayed on W20CL (channel 20) inSpringfield, Ohio, and W36DG (channel 36) in Cincinnati. A deal was reached to sell W20CL (nowWLWD-LD in Dayton)^[12] to Word of God Fellowship, owner of theDaystar Television Network, on March 19, 2010;^[13] W36DG was also sold to Daystar, and is nowWDYC-LD.^[14][15][16]
