On March 5. 1979, ABC moved its affiliation to KSTP; leaving KMSP as an independent station.
KMSP would resume its status as a network affiliate in October 1986, when it became a charter outlet of the upstarting Fox network. The station disaffiliated from Fox in 1988, due to dissatisfaction with the network's low-rated programming and its affect on KMSP's prime time viewership; the Fox affiliation in the Twin Cities subsequently moved to KITN (now sister station WFTC).
Following another six-year tenure as an independent station, KMSP became a charter affiliate of UPN when that network launched on January 16, 1995, joining the network by way of the station's ownership under UPN co-parent Chris-Craft/United Television.
KMSP-TV became a Fox station for the second time in September 2002, as part of an affiliation swap between the two stations following WFTC's 2001 acquisition by Fox Television Stations Group from Clear Channel; FTSG also purchased KMSP from Chris-Craft in 2001, but kept the UPN affiliation on KMSP until after the expiration of its affiliation agreement with that network.
This logo branding, currently in use by most of the Fox O&Os, is based on the Fox News logo; with their website names ("myfox(city name).com") based off the domain for the social network Myspace, which former Fox parent News Corporation briefly owned.
