GYMS

1995
In 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. Since News Corporation didn't own Fox's local affiliate GNCM, the company opted to sell GUPC to Meredith Corporation, 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.

2006-2015
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 as part of sister station GNCM's affiliation agreement with Fox's parent company News Corporation. To reflect its new affiliation, its call letters were changed into GYMS. In 20??, 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.
