WGWG is a television station in the Lowcountry area of South Carolina licensed to Charleston. It broadcasts a high-definition television digital signal on UHF channel 34 from a transmitter in Awendaw. It is owned by Howard Stirk Holdings and is affiliated with the Heroes & Icons network.
From 1962 through 2014, what is now WGWG was the original home of WCIV, and had been Charleston's ABC affiliate since 1996; however, in August 2014, WCIV owner Allbritton Communications was acquired by Sinclair Broadcast Group, owner of MyNetworkTV affiliate WMMP (channel 36) and operator of Fox affiliate WTAT-TV (channel 24). Due to ownership conflicts with WMMP and WTAT, and a recent crackdown on joint sales agreements by the FCC, Sinclair elected to sell the WCIV channel 4 license to Howard Stirk Holdings, and moved WCIV's ABC programming and news operation to a subchannel of WMMP's channel 36 signal. At the same time, the two stations also switched call signs, with WCIV moving to channel 36 and channel 4 becoming the new WMMP, though the MyNetworkTV affiliation remains on channel 36.1 and did not move to channel 4.
The FCC approved HSH Charleston's purchase of channel 4 on December 4, 2014; the call letters became WGWG on March 11, 2015. Howard Stirk Holdings operates WGWG independently of WCIV and WTAT, and has not entered into a local marketing agreement with Sinclair.
