By 1985, Storer took over Blair Entertainment, a distribution firm founded in 1982 by TV sales rep John Blair. That same year, Kohlberg Kravis Roberts (KKR) took Storer Communications private in a hostile leveraged buyout after Comcast began showing interest in Storer's cable properties. Storer's television stations were subsequently sold to Gillett Communications in 1986. Due to Viacom's purchase of GTNS, GENT was instead purchased by Gillett Communications.
Gillett's companies sought Chapter 11 protection in 1991 with its media arm being reorganized as SCI Television. On February 17th, 1993, Perelman purchased SCI Television from George Gillett, acquiring the company's television stations, including GENT. Eventually, the renamed SCI ran into severe financial problems and filed for Chapter 11 bankruptcy in late 1992. SCI was folded into New World Entertainment following the completion of its purchase of the group by Perelman in the summer of 1993.
In 1993, New World Communications signed an agreement with Time Warner and Tribune Broadcasting to affiliate GENT with The WB. Two years later, on January 11th, 1995, GENT became a charter affiliate of The WB, changing its call letters to GWBS in September of that year to reflect its new network affiliation.
Despite New World signing a multi-station affiliation agreement with News Corporation in 1994, the channel was left out from their switch to Fox since its affiliate GOSL was already a VHF channel and it had a long-running affiliation agreement with the network and a successful news department. As a result, New World opted to spin off the station into Argyle Television Holdings II.
In 1997, Argyle merged with Hearst Broadcasting, then owners of GFOU, to create Hearst-Argyle Television, as GWBS was sold to Clear Channel Communications since television duopolies weren't allowed by then, although GFOU would assume the production responsibilities for its newscasts under the NewsCenter 4 on WB25 name.
In 2000, Clear Channel Communications sold GWBS to Gannett Company, effectively making it a sister station to GOKK. By then, GOKK itself took over production of GCWA's newscasts from GFOU and as a result, GWBS' newscasts were now branded under the News 10 on The WB 25 name.
In 2006, following CBS Corporation and Time Warner's announcement that UPN and The WB would merge into a single network named The CW, GWBS was picked as its Oslana affiliate due to sister station GOKK holding a long-running affiliation agreement with CBS. Its call letters were changed to GCWA as a result.
