Canadian CBC), and was also predominately used at CBS (which has most of its owned-and-operated stations, with a few exceptions, brand using a combination of the network's name and over-the-air channel number) and The WB (with the exception of its Tribune Broadcasting-owned affiliates in Los Angeles and Chicago, and certain other stations); NBC and ABC also use similar branding schemes, but not to the same broad level outside their O&Os. While the "Big Three" networks do not require their affiliates to have such naming schemes (though some affiliates choose to adopt it anyway) and only on the network's O&Os is the style required, UPN mandated it on all stations – though in one case, Milwaukee affiliate WCGV branded as "Channel 24" from 1998 to 2001, excluding UPN imagery from its station branding (WCGV, which previously branded as "UPN 24", had disaffiliated from the network for eight months in 1998 due to a compensation dispute; it received a rare waiver from the network to air a marathon of the last half of season four of Star Trek: Voyager which it had not aired in August 1998, before the fifth season's premiere in September.). One Chris-Craft/United Television-owned station, KMSP-TV in Minneapolis–Saint Paul, only branded as "UPN 9" for its entertainment and network programming. Due to the station's circumstances of holding full cable carriage across the state of Minnesota and into The Dakotas as a superstation, local management preferred to retain their pre-UPN "Minnesota 9" branding in some manner, as most of the UPN schedule was of low appeal to the station's rural viewers, and it was building a successful and competitive news department that did not depend on the success or failure of UPN. KMSP's news division success despite UPN affiliation was one of the pushes for Fox Television Stations to acquire United Television overall, then convert KMSP-TV to a Fox owned-and-operated station in Fall 2002. The UPN affiliation thus moved to new sister station WFTC, which followed all UPN branding guidelines until Fox pulled their support for the network in January 2006.
