KRRT switched affiliation from Fox to UPN as a charter O&O station when it launched on January 16, 1995, while the Fox affiliation was moved to KABB. During this logo's run, Paramount/Viacom would sell the station to Jet Broadcasting which would operate the station under a LMA with River City. (owners of KABB) River City was later sold to the Sinclair Broadcast Group in 1997. Glencairn, Ltd (now Cunningham Broadcasting, a partner company of Sinclair) would purchase KRRT in 1998.
