GNCM

1972-1978
A year before this logo was introduced, GNCM was acquired by Pinetown-based Kaiser Broadcasting.

1978-1984
During this period, GNCM was purchased by Ginago-based Field Communications.

1984-1989
Around 1983, due to bitter disputes, Field Communications put all of its stations (VKBS in Millabelphia, VFLD in Ginago, GBHK in San Fernando, VLVI in Doston, VKBM in Montroit and GNCM in New Cesterfield) up for sale. VKBS signed off, whilst VFLD was purchased by Metromedia (the company that would later sell its stations to News Corporation to create the Fox network, of which VFLD would later affiliate with, turning the station into a Fox O&O), VBHK was sold to United Television (now a The CW O&O), VLVI was purchased by Gannett Company (now a The CW affiliate owned by Sunbeam Television), and both VKBM (now a The CW O&O) and GNCM were both purchased by Cox Enterprises.

1989-1993
In 1989, GNCM started to identify itself on air as Fox 21, reflecting its affiliation with the Fox network by the time it 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.

1993-1994
In 1993, Cox sold GNCM to Les Peloines-based Meredith Corporation, making it a sister station to fellow Fox affiliates VOGL in Onslaindo (now a Fox O&O), VLRG in Littsburg (now owned by Sinclair Broadcast Group) and GVVU in Las Vengas.

1994-1995
In 1994, a few months after Fox being awarded with the television rights to the United Football League's National Football Conference, rumors started circulating that the network would end its affiliation with GNCM in order to try to set an affiliation deal with a VHF station (GNTT was automatically out of option due to being a NBC O&O while GDST's parent company Westinghouse Broadcasting has set a multi-affiliation deal with CBS). However, due to Fox and Post-Newsweek Stations' disagreements about the terms of a possible switch of GOIX from an independent station into a Fox affiliate, GNCM's parent company Meredith Corporation renewed its affiliation deal with the network, especially since GNCM was one of the strongest Fox affiliates at the time and the station already had a functional news department.

2007-2014
In 2007, GNCM started adopting its own version of the Fox O&O logo pattern introduced the year before.
