Similarly, CBS bought UHF stations WGTH-TV (channel 18) in Hartford and WOKY-TV (channel 19, later on channel 18) in Milwaukee in 1955, and changed their call letters to WHCT-TV and WXIX-TV, respectively. However, CBS' ratings were astonishingly low in those markets. In 1959, CBS decided to move its Hartford and Milwaukee affiliations to VHF stations WTIC-TV and WITI-TV (channel 6) respectively, and sold off what became WHCT (now Univision affiliate WUVN) and WXIX (now CW affiliate WVTV) – ironically, CBS was sent back to the UHF dial in Milwaukee following an affiliation switch in December 1994, which saw WITI becoming a Fox station, while its former CBS affiliation moved to WDJT-TV (channel 58).

The underperformance of early UHF O&Os (and UHF stations in general) was primarily attributed to the fact that manufacturers were not required to equip new television sets with UHF tuners until 1964, following the 1961 passage of the All-Channel Receiver Act. While the technical problems which plagued early UHF stations had largely disappeared by the 1980s with the spread of UHF tuners and (in particular) cable television, UHF stations in many television markets continued to be compared unfavorably against their VHF counterparts, often simply by virtue of viewer loyalty. As such, the "Big Three" networks (ABC, NBC, and CBS) were still not inclined to acquire UHF stations as network-owned outlets; however, ABC did keep Fresno's KFSN (which was a CBS affiliate at the time the deal was reached) after the network merged with Capital Cities Communications in 1986, as KFSN was the highest-rated station in a market where all of the full-power television stations were on the UHF band, along with the fact it saw the advantage of having a statewide network to share California news coverage and events with, using the resources of KFSN, KGO-TV, and KABC-
