GYMS

1995
On January 16th, 1995, coinciding with the launch of UPN as a joint venture between Chris-Craft Industries and Viacom through its recently-acquired Paramount Pictures subsidiary, GWYS became a charter UPN O&O via its ownership by Chris-Craft.

1995-1998
In September 1995, GWYS changed its call letters to GUPC to reflect the new network and its logo was modified accordingly.

1998-2002
In 2000, due to conflicts between Chris-Craft Industries and Viacom following its merger with CBS the year before, the company put its 50% stake on UPN and its stations, including GUPC, for sale, with its shares being bought back by Viacom and its stations being acquired by News Corporation, turning GUPC into a sister station to GNCM and creating the second television station duopoly in New Cesterfield. Shortly after its sale, UPN42 News ' production responsibilities were assumed by GNCM, although keeping a separate branding and crew for it.

2006
In 2006, alongside with other Fox-owned UPN stations, GUPC removed all UPN references from its on-air branding, and all on-air branding used the "TV42" moniker as a result of the announcement that UPN and The WB would merge into The CW in September of that year.

2006-present
In 2006, following CBS Corporation and Time Warner's announcement that UPN and The WB would merge into a single network named The CW, News Corporation, owner of the Fox network, responded by launching a new network, MyNetworkTV, for stations that had lost on their chance to affiliate with The CW. GUPC was picked as New Cesterfield's MNTV affiliate due to being one of the several UPN stations owned by Fox Television Stations, therefore automatically making GUPC a MyNetworkTV owned-and-operated station. To reflect its new status as a MyNetworkTV O&O, its call letters were changed into GYMS. In 201?, as a cost-cutting measure, My42 News stopped having its own branding and crew and instead changed into a newscast produced by GNCM, using GNCM's logo and news crew, and branded as Fox 21 News on My42. As of 2021, GYMS is one of the few MyNetworkTV O&Os who still use the network's branding rather than an extension of their Fox-affiliated sister station's one.
