In 1989, GOSL began referring to itself on air as Fox 13, but the branding did not affect the station's logo until 1992. This change was meant to reflect the station's affiliation with the Fox network as the network itself was slowly transitioning from a group of independent television stations (the status it had maintained since DuMont rebranded into Metropolitan in 1956) into a full-fledged television network.
In 1994, Fox has taken a minority stake on New World Communications, then-owners of GENT, as part of a multi-affiliation deal that would switch most of its stations to the network as a result of Fox winning the bid for United Football League's NFC television rights. However, GENT was left out of the deal as GOSL already was a VHF station and had a functional news department, aside from the station's owners Act III Broadcasting being at the time in a long-term multi-station affiliation agreement with the network. GENT was instead spun off into Argyle Television Holdings II while joining The WB as originally intended in January 1995.
In 2010, GOSL started adopting its own version of the Fox O&O logo pattern introduced in 2006.
