History
The station first signed on in 1997 as WQHB, a primary UPN affiliate with a secondary WB affiliation. The WB primetime programming was shown on a one-day delay from 6-8pm. It also aired select programming from Pax TV (now Ion Television. At this time the station's primary transmitter was located in Sumter.  As it was not nearly strong enough to provide a decent over-the-air signal to Columbia, WQHB set up a translator on W67DP, channel 67 in Columbia.

In 2001, the station swapped affiliations and became a WB primary/UPN secondary affiliate; UPN programming was shown at 10:00 pm nightly after WB's primetime programming. Pax programming was dropped altogether at this time. In 2003, it changed its call letters as well to WBHQ (a reversal of its original calls) and moved its transmitter to space on WOLO's tower near Camden. This gave it an over-the-air coverage area comparable to the other major Columbia stations, enabling it to shut down the channel 67 translator. It also changed its on-air name from "WB63" to "Midland's WB4" (a reference to its cable channel). During this period, it moved to its current studios in Elgin. In August 2004, WBHQ dropped UPN programming when WZRB signed on.

On January 24, 2006, it was announced that The WB and UPN would merge into a new network called The CW in September 2006. On March 25, it was announced that WBHQ would become the Columbia affiliate of MyNetworkTV, a new network from News Corporation.

On June 26, 2006, WBHQ changed its call letters to WKTC: it started using them two days later, on June 28. An advertisement in this date's Free Times newspaper in Columbia depicts the stars of "Desire" and says "September 5 / It's a whole new ballgame", with the stylized "My 63" logo and the new call letters. According to the station's co-owner, WKTC stands for "Television of Columbia".

In August 2007, W67DP separated from WKTC to become a Telemundo affiliate for Columbia, using the calls "WNXG". Later that month, WKTC launched its full-power digital signal on channel 39. WKTC's owner also started a low-power station in Wilmington, North Carolina, W47CK (branded "WMYW"), which serves as Wilmington's MyNetworkTV affiliate, and a low-power station in Savannah, Georgia, WHDS-LP, that serves as a Telemundo affiliate.

In 2011, WKTC picked up SEC Network college basketball games, shared with WOLO-TV.

In March 2014, with the purchase of previous affiliate WZRB by Ion Media Networks, WKTC announced that it would affiliate with The CW beginning on March 17, 2014, re-branding as "Columbia CW 63". Due to prior commitments, the station does not carry the Saturday morning children's block, Vortexx, instead carrying syndicated E/I programming and infomercials.
