Owned-and-operated television stations in the United States


In the United States, owned-and-operated television stations constitute only a portion of their parent television networks' station bodies, due to ownership limits imposed by the Federal Communications Commission. Currently, the total number of television stations owned by any company can only reach a maximum of 39% of all U.S. households; in the past, the ownership limit was much lower, and was determined by a specific number of television stations rather than basing the limits on total market coverage.

Distribution

At the dawn of the American television industry, each company was only allowed to own a total of five television stations around the country. As such, when the networks launched their television operations, they found it more advantageous to put their five owned-and-operated stations in large media markets that had more households on the belief that it would result in higher revenue. In other markets, they opted to run their programming on stations through contractual arrangements, making them affiliates instead.
The five-station limit posed a problem for the DuMont Television Network, the first attempt at a "fourth" television network. Paramount Pictures, which had owned KTLA in Los Angeles and WBKB in Chicago, owned a share of the network. However, the FCC declared that Paramount controlled DuMont and thus forbade the network and the studio from acquiring any more stations. This was one of the factors that led to DuMont shutting down in August 1956.
For much of the era from 1958 to 1986, the major network-owned stations were distributed as follows: ABC, CBS and NBC each owned stations in the top three markets. Between 1958 and 1965, fourth-ranked Philadelphia housed CBS-owned WCAU-TV and NBC-owned WRCV-TV, a station which NBC had acquired two years earlier through a trade with Westinghouse Broadcasting in return for NBC's television and radio stations in Cleveland. The FCC reversed the trade in 1965 and NBC regained control of the Cleveland television station, which is today known as WKYC. Each network owned stations in other markets where the other networks did not: in addition to Cleveland, these were ABC's KGO-TV in San Francisco and WXYZ-TV in Detroit, NBC's WRC-TV in Washington, D.C., and CBS' KMOX-TV in St. Louis.
As a result of a revision to the FCC's media ownership rules in 1999, a company can now own any number of television stations with a combined market reach of less than 39% of the country, but cannot own two of the four highest-rated stations in any market. Still, O&Os in the United States are primarily found in large markets such as New York City, Los Angeles and Chicago, among others. Despite that, network-owned stations can still be found in smaller markets in Fresno, California is an ABC O&O; WOGX.

UHF vs. VHF

Early development

Local television stations in the United States were concentrated on the VHF dial in the early days of the industry. However, it soon became apparent that the twelve channels available on the VHF dial would not be sufficient to meet the demands of the growing industry. As a result, in 1952, the FCC opened up a new spectrum of frequencies on the UHF dial for terrestrial television. As an incentive for companies to operate UHF stations, the FCC relaxed the ownership limit for a given entity from five to seven stations, provided that no more than five were on the VHF dial.
With this opportunity to expand its roster of O&Os, NBC bought WBUF-TV in Buffalo in 1955 and WKNB-TV in New Britain, Connecticut in 1957, and changed WKNB's call letters to WNBC-TV. The network wanted to see if a UHF station could effectively compete against VHF stations, and attempted to make the stations more competitive by investing in significant equipment upgrades. However, WBUF consistently ranked behind its VHF competitors, WGR-TV and WBEN-TV. Similarly, WNBC consistently rated behind VHF competitor WNHC-TV ; WNBC faced an additional problem as its signal was not strong enough to cover New Haven and western Connecticut.
By the time the FCC allocated additional VHF stations to Buffalo and Hartford, NBC decided that its experiment was a lost cause, and put WBUF and WNBC up for sale. While it found a buyer for WNBC, there were no takers for WBUF, and it went off the air in 1958. NBC then affiliated with WGR-TV, where it remains to this day. NBC donated WBUF's license and some of its equipment to PBS member station WNED-TV, which took over the channel 17 frequency in 1959.
Similarly, CBS bought UHF stations WGTH-TV in Hartford and WOKY-TV 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 respectively, and sold off what became WHCT and WXIX – 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.

1980s and beyond

The underperformance of early UHF O&Os 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 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 were still not inclined to acquire UHF stations as network-owned outlets; however, ABC did keep Fresno's KFSN 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-TV.
By the time the Fox network launched in October 1986, many of the nation's VHF stations were already affiliated with one of the "Big Three" networks. As a result, Fox had little choice but to affiliate with UHF stations in most markets upon its launch. The network even had UHF O&Os in markets like Chicago, Houston, and Dallas. However, by the time that the National Football League awarded Fox the rights to broadcast games from the National Football Conference in 1993, it became convinced that the network would not be viable without more VHF affiliates. As such, in May 1994, the network arranged a deal with New World Communications, which saw nearly all of that group's stations becoming Fox affiliates. Fox then acquired New World Communications outright in July 1996, and those VHF stations became Fox owned-and-operated stations in the process. The network, however, did acquire more UHF O&Os in subsequent years, including Philadelphia's WTXF-TV in 1995, Orlando's WOFL in 2002, and Charlotte's WJZY in 2013.
As a result of the New World deal, CBS lost its longtime Detroit affiliate WJBK to Fox. CBS then unsuccessfully sought to affiliate with other stations in the market before it eventually purchased low-rated ethnic independent WGPR-TV and changed the station's callsign to WWJ-TV in 1995. The station continues to receive low ratings, and after a brief attempt at running an 11:00 p.m. newscast from 2001 to 2002 that was produced by sister station WKBD-TV, was the only CBS owned-and-operated station without a local news presence until 2009, when a morning newscast produced by the Detroit Free Press premiered. CBS also bought KEYE-TV in Austin, Texas from the Granite Broadcasting Corporation in 2000, five years after that station took the CBS affiliation from KTBC, another former New World station that switched to Fox.
NBC would not buy a UHF O&O again until 1995, when it acquired WNCN in Goldsboro, North Carolina. It subsequently purchased KNSD in San Diego in 1996, and it repurchased channel 30 in Hartford, now WVIT, in 1997.
Currently, most American networks have at least one owned-and-operated station on a UHF frequency. Newer networks, such as Univision and Ion Television, even have mostly UHF O&Os.

Ownership and network changes

Mergers, acquisitions, and other business deals between television networks and other companies sometimes require a network to sell off an O&O, in order to stay under the ownership cap. In addition, networks may choose to sell off O&Os in smaller markets in order to concentrate on their stations in larger markets, or to give themselves leeway to purchase stations in other growing markets. The following are examples of transactions involving owned-and-operated stations in the United States:

DuMont Television Network

The DuMont network found itself in financial trouble in 1954, and decided to sell off its Pittsburgh owned-and-operated station, WDTV, which was the only commercial VHF station in what was then a top ten television market in the United States. Westinghouse Electric Corporation bought the station for $6.75 million, and changed its call letters to KDKA-TV.
However, even with income generated from the sale, DuMont was never able to recover from its problems, and the network shut down in August 1956. Its two other owned-and-operated stations, WABD in New York City and WTTG in Washington, D.C., became independent stations and remained so until October 1986, when they became Fox O&Os at the network's inception.

CBS

In 1986, CBS sold its longtime owned-and-operated station in St. Louis, KMOX-TV, to Viacom. Viacom changed the station's callsign to KMOV, then sold it to Belo in 1997, in a three-way swap that also saw Viacom acquiring KSTW in Seattle–Tacoma from Cox Enterprises, and that company in return getting KIRO-TV from Belo. Belo merged with the Gannett Company in 2013; as a condition of the deal, KMOV was acquired by the Meredith Corporation in 2014. CBS purchased KOVR in Stockton, California from the Sinclair Broadcast Group in May 2005.
On February 7, 2007, CBS announced the sale of its owned-and-operated stations in Salt Lake City and Austin to Four Points Media Group, a holding company owned by Cerberus Capital Management as part of a group deal which also included two CW owned-and-operated stations, one low-power MyNetworkTV affiliate and one low-power Azteca América affiliate. Six days later, CBS announced that it was swapping its O&O in Green Bay, WFRV-TV, and its satellite in Escanaba, Michigan, WJMN-TV, to Liberty Media in exchange for common CBS stock held by Liberty Media; the sale of WFRV/WJMN closed on April 18, 2007. The Four Points transaction was approved by the FCC on November 21, 2007, and was finalized on January 10, 2008. In 2012, the Four Points stations were acquired by the Sinclair Broadcast Group; WFRV/WJMN was sold to the Nexstar Broadcasting Group in 2011.

NBC

For much of the modern television era, NBC did not have an owned-and-operated station in Philadelphia. In 1955, NBC forced Westinghouse to trade its NBC-affiliated Philadelphia cluster of KYW-AM and WPTZ-TV to NBC in exchange for WTAM-AM-FM and WNBK-TV in Cleveland. Westinghouse only agreed to the trade after NBC threatened not only to yank its programming from WPTZ, but also Westinghouse-owned WBZ-TV in Boston. NBC changed the callsigns of the Philadelphia stations to WRCV-AM-TV, while Westinghouse changed the Cleveland stations' callsigns to KYW-AM-FM-TV. NBC's then-ownership of Philadelphia's channel 3 was cited by CBS when it purchased its then-affiliate WCAU-TV in 1958, despite FCC rules at the time barring companies from owning stations with overlapping signals, as WRCA/WRCV did.
In 1965, NBC was forced to reverse the trade on orders from the Federal Communications Commission and the United States Department of Justice. WRCV-TV's callsign was then changed to KYW-TV to match its radio cousin. When NBC regained control of the Cleveland stations, it changed their callsigns to WKYC-AM-FM-TV, because of the AM station's popularity as "KY11". It sold the radio stations in 1972, but kept WKYC-TV until 1990, when majority control of the station was sold to Multimedia, Inc. ; NBC remained minority owner of WKYC-TV until 1999 when it sold its remaining interest to Gannett. NBC continued to pursue efforts to acquire an owned-and-operated station in Philadelphia, especially when KYW became its weakest major-market affiliate for much of the 1980s. However, NBC was unsuccessful until 1995, when it won a bidding war for longtime CBS O&O WCAU-TV.
In 1997, LIN TV Corporation sold a 76% stake in Dallas-Fort Worth's KXAS-TV to NBC in exchange for 24% of San Diego's KNSD; therefore, NBC owned 76% of both stations. Although this was not defined as a traditional O&O arrangement, NBC's controlling interest in the stations allowed them to be considered NBC owned-and-operated stations. In February 2013, LIN pulled out of the joint venture, giving NBC 100% ownership of the two stations.
In December 2001, NBC acquired an O&O in the San Francisco Bay Area, when it purchased San Jose-based KNTV from the Granite Broadcasting Corporation; the sale to NBC was finalized in April 2002. Prior to the purchase, KNTV had been affiliated with ABC for most of its history, while NBC was affiliated with KRON-TV ; by 2000, ABC wished for its own longtime San Francisco O&O station, KGO-TV, to exclusively serve the San Jose portion of the market and terminated its 40-year affiliation with KNTV; while KRON, which had recently been sold to Young Broadcasting, opted to end its NBC affiliation after 52 years in the wake of a dispute with NBC over the terms of the renewing the station's affiliation contract. Granite, which had been operating KNTV as a WB affiliate since it ended its affiliation with ABC, offered to pay NBC a then unheard-of annual payment of $37 million for the station to become an NBC affiliate, an offer which NBC accepted before later finalizing the outright acquisition.
On March 19, 2008, NBC announced its intention to sell two additional O&Os: WTVJ in Miami and WVIT in New Britain-Hartford, Connecticut. On July 18 of that year, it was announced that WTVJ would be sold to Post-Newsweek Stations, then owner of Miami's ABC affiliate WPLG. Had the FCC approved this deal, it would have resulted in the Miami market being home to the largest duopoly in the United States between two "Big Three" or "Big Four" network affiliates. WVIT was later withdrawn from the selling block, as all of the offers made for that station were much lower than NBC's asking price. The sale of WTVJ also fell through due to the delay in FCC approval for the deal, the election of Barack Obama as president effectively de facto signaling a rejection of the deal from a Democratic-led FCC board of commissioners was coming, and public opposition over the proposed sale of WTVJ to the owner of another major network station.
In 2016, NBC announced that it would launch a new O&O in Boston on January 1, 2017, replacing WHDH-TV as the network's Boston affiliate.

ABC

Detroit's WXYZ-TV had been an ABC owned-and-operated station from its sign-on in 1948, as WXYZ radio had been an affiliate of ABC radio's predecessor, the NBC Blue Network. However, when Capital Cities Communications acquired ABC in 1985, the combined assets of the new company exceeded the FCC's ownership limit at the time. As such, the network opted to sell WXYZ to the E. W. Scripps Company, having remained with ABC ever since then as an affiliate of the network.
During the series of network affiliation switches that was spurred by Fox's 1994 deal with New World Communications, ABC bought two stations in markets adjacent to Detroit: WTVG in Toledo, Ohio and WJRT in Flint, Michigan – specifically in order to keep some fringe suburban coverage of its programming in the Detroit market, in the event that Scripps would attempt to affiliate WXYZ-TV with another network, resulting in a possible move of ABC to a lower-tier station in the market. Though WXYZ stayed with ABC after Scripps agreed to keep that station affiliated with the network in exchange for affiliation deals with stations that the company owned in other cities, ABC decided to retain ownership of WTVG and WJRT.
Capital Cities also owned two CBS affiliates – Fresno's KFSN and Raleigh-Durham's WTVD – and chose to switch them both to ABC. CBS programming moved to former ABC affiliates in the two markets, WRAL-TV in Raleigh-Durham and KGPE in Fresno; WRAL was one of CBS's strongest affiliates until it switched to NBC in 2016, instead becoming one of NBC's strongest affiliates.
On November 3, 2010, ABC reached an agreement to sell WJRT and WTVG back to former owner SJL Broadcasting, amidst speculation that The Walt Disney Company might spin off ABC; both stations retained their ABC affiliations. When the sale was completed, KFSN in Fresno would then become the smallest English-language owned-and-operated major network station by market size. The sale was completed on April 1, 2011. The Disney spin-off of ABC has never occurred, mainly due to insider trading allegations that scuttled the deal.

Fox

In 1987, Fox purchased its Boston affiliate, WFXT. The network's then-parent company News Corporation also owned The Boston Herald, requiring Fox to obtain a temporary cross-ownership waiver for the station. When the waiver to retain ownership of both the newspaper and television station expired, WFXT was sold to the Boston Celtics of the National Basketball Association. The Celtics could not survive as a broadcaster, and Fox purchased WFXT a second time in 1995 after the Herald was sold.
As a result of the aforementioned Fox/New World partnership, Fox had to sell off its original O&Os in Dallas and Atlanta, respectively selling them to Renaissance Broadcasting and Qwest Broadcasting. KDFW and WAGA-TV became Fox owned-and-operated stations in the respective markets after Fox Television Stations merged with New World Communications.
On June 13, 2007, Fox announced its intention to sell nine of its owned-and-operated stations: WJW in Cleveland, Ohio; KDVR in Denver, Colorado; KTVI in St. Louis, Missouri; WDAF-TV in Kansas City, Missouri; WITI in Milwaukee, Wisconsin; KSTU in Salt Lake City, Utah; WHBQ-TV in Memphis, Tennessee; WBRC in Birmingham, Alabama and WGHP in Greensboro, North Carolina. On December 21 of that year, it was announced that eight of the stations – WHBQ being the only one not included – would be sold to Local TV, a broadcast holding company controlled by the private equity firm Oak Hill Capital Partners; the sale closed on July 14, 2008.
Of the eight former Fox O&Os involved in the sale to Local TV, WBRC ended up being traded to Raycom Media on March 31, 2009, in exchange for Richmond, Virginia CBS affiliate WTVR-TV ; WBRC was subsequently acquired by Gray Television as part of its merger with Raycom, which was completed on January 2, 2019. WHBQ was later withdrawn from the selling block after Fox failed to find a suitable buyer for the station, as both Local TV and Raycom both already owned stations in that market and WMC-TV which would easily put them over the FCC's market ownership caps, and the only other buyer that might have been interested – Newport Television – already owned two stations in Memphis at the time: WPTY-TV and WLMT. The remaining seven former Fox O&Os were acquired by Tribune Broadcasting as part of its purchase of Local TV, an acquisition that closed on December 27, 2013. Sinclair Broadcast Group would announce its acquisition of Tribune in 2017, which would have seen Fox reacquire WJW, KSTU, and KDVR and acquire WSFL-TV in Miami, KSWB-TV in San Diego, KTXL in Sacramento, and KCPQ-TV in Seattle, which all would have become owned-and-operated stations of the network; however, Tribune terminated the deal in August 2018.
On June 24, 2014, Fox announced that it would trade WFXT and WHBQ to the Cox Media Group, in exchange for the San Francisco duopoly of Fox affiliate KTVU and independent station KICU-TV, which Fox had sought to acquire for several years. The trade was completed on October 8, 2014.
In December 2018, Nexstar Media Group announced its acquisition of Tribune. As was the case with Sinclair's failed acquisition of the company, Fox sought to buy certain Fox-affiliated stations owned by Tribune, with KDVR, KCPQ, and WJW emerging as potential candidates. However, in March 2019, Nexstar announced that KSTU and WSFL-TV would be acquired by the E.W. Scripps Company; Nexstar intended to retain KSWB, KTXL, WJW, KCPQ, and KDVR after the transaction is completed. Two months after the close of the Nexstar deal, Fox Television Stations and Nexstar announced a swap, where Fox will acquire KCPQ and KZJO in Seattle, along with a re-acquisition of WITI in Milwaukee, with Nexstar acquiring Fox's Charlotte, North Carolina duopoly of WJZY and WMYT-TV.

The WB

From January 1995 to September 2006, Time Warner and Tribune Broadcasting jointly owned The WB Television Network. Tribune initially held a 12.5% ownership interest in the network at its launch, a stake that it later increased to 22%. As a result of its partnership, in November 1993, Tribune agreed to a deal to affiliate most of its independent stations with The WB. Despite Tribune's minority stake, the company's stations were not considered to be WB owned-and-operated-stations due to Time Warner's controlling interest in the network. This resulted in The WB having the unusual distinction of being the only broadcast network that did not have O&Os in New York City, Los Angeles and Chicago throughout its existence.
However, Tribune was the only one of the two companies involved in The WB that owned any stations aligned with the network as Time Warner did not own any television stations at the network's launch and would not own one until its 1996 merger with the Turner Broadcasting System, owners of Atlanta superstation WTBS. On January 24, 2006, Time Warner and CBS Corporation announced that they would merge The WB with the CBS-owned United Paramount Network to form a new broadcast network called The CW. All except three of Tribune's 19 WB stations joined The CW when it launched on September 18, 2006, through ten-year affiliation agreements in San Diego and WTTV in Indianapolis – have since disaffiliated from the network under Tribune ownership, while another – WLVI. Tribune, however, does not have an ownership interest in The CW, having opted to forego a stake in the network in order to avoid having to finance shutdown costs for The WB.
ACME Communications, which operated WB-affiliated stations in small and mid-sized markets, was owned by Jamie Kellner, the network's president from its 1995 launch until 2001. However, neither Time Warner or Tribune considered the ACME stations on the same level as the Tribune stations, nor did Time Warner have any interest in the stations outside of traditional affiliation agreements, or vice versa did ACME have any interest in Time Warner. The ACME stations were among the first awarded de facto affiliations for The CW when the network began to open up affiliation negotiations in March 2006.

UPN

UPN stations that were formerly owned by Chris-Craft Industries and those that were owned by CBS Corporation at the end of the network's run were sometimes considered owned-and-operated stations of the network, and several transactions have involved these stations. Not too long after becoming a UPN owned-and-operated station itself, San Antonio station KRRT was sold to Jet Broadcasting in 1995, eventually becoming an affiliate of The WB.
On August 12, 2000, Chris-Craft sold its UPN stations to the Fox Television Stations subsidiary of News Corporation for $5.5 billion – these stations had been stripped of their status as UPN owned-and-operated stations earlier that year due to Viacom's buyout of Chris-Craft's stake in the network, but remained with UPN as affiliates. Of those stations, San Francisco's KBHK was traded to the Paramount Stations Group, while Portland's KPTV was traded to the Meredith Corporation. Both KPTV and former Minneapolis-St. Paul sister station KMSP-TV traded their UPN affiliations with Fox affiliates in those markets that they respectively became co-owned with, WFTC and KPDX. Fox had acquired WFTC from Clear Channel Communications not long after the Chris-Craft purchase was finalized, while Meredith already owned KPDX at the time it purchased KPTV. The other UPN stations that remained under Fox ownership retained their affiliations with that network, but were no longer O&Os – giving UPN the distinction of being one of only two broadcast networks whose stations in the three largest markets of New York, Los Angeles and Chicago were not owned-and-operated stations ; WWOR-TV in Secaucus, New Jersey and KCOP-TV in Los Angeles were de facto O&Os prior to Viacom's buyout of Chris-Craft's stake in UPN, while WPWR-TV in Chicago was an affiliate of UPN throughout the network's run.
In September 2006, these stations became O&Os of MyNetworkTV, which was created in response to The CW's decision to affiliate stations owned by Tribune Broadcasting and network part-owner CBS Corporation's CBS Television Stations subsidiary with the network instead of Fox's UPN-affiliated stations. In fact, two of the former Chris-Craft stations have the distinction of being owned-and-operated stations of two networks: WWOR-TV, and KCOP-TV, both having been O&Os of UPN and MyNetworkTV.
Viacom/CBS sold off several UPN owned-and-operated stations during the network's final five years. Mercury Broadcasting bought Wichita, Kansas' KSCC in 2001 ; KTXH in Houston and WDCA in Washington, D.C. were sold to Fox Television Stations that same year. In 2005, WNDY-TV in Indianapolis and WWHO in Columbus were sold to LIN TV; in 2006, KAUT-TV in Oklahoma City was sold to The New York Times Company, and in 2008, WUPL in New Orleans was sold to Belo.

The CW

Because of CBS Corporation's ownership stake in The CW Television Network, while not a traditional O&O arrangement, stations owned by the company that carry programming from the network can be considered O&Os. In February 2007, as part of the aforementioned group deal that included two of CBS's O&Os, CBS Corporation sold its CW owned-and-operated stations in West Palm Beach, Florida and Providence to Four Points Media Group. The Four Points stations were subsequently acquired by the Sinclair Broadcast Group; WLWC, in turn, has since been spun off to OTA Broadcasting, LLC.
In June 2010, CBS announced the sale of its Norfolk, Virginia CW O&O WGNT to Local TV, then owner of that market's CBS affiliate WTKR-TV . This created the second television duopoly in that market and Fox affiliate WVBT ). As part of the deal, Local TV would take over the operations of WGNT through a time brokerage agreement while the deal awaited FCC approval. Until the sale closed on August 4, WGNT was the smallest station by market size to be owned by CBS following the Four Points Media Group deal. The sale of WGNT also made WJZ-TV in Baltimore the smallest station by market size that is still owned by CBS.

Other networks

In 1999, not long after Ion Television launched as Pax TV, its parent company Paxson Communications sold its Dayton, Green Bay and Decatur O&Os – WDPX, WPXG and WPXU, respectively – to ACME Communications; the stations later changed their respective callsigns to WBDT, WCWF and WBUI. All three stations then became primary affiliates of The WB ; the stations are now CW affiliates.
Two years later, in 2001, Pax sold its Little Rock owned-and-operated station KYPX to Equity Broadcasting, which switched the station's affiliation to The WB as KWBF. In 2003, Pax sold its Albuquerque, New Mexico O&O, KAPX, to Univision Communications, which turned it into an O&O of TeleFutura. That same year, Paxson sold KPXJ in Shreveport, Louisiana, to KTBS, Inc. ; that station became a UPN affiliate and is also now an affiliate of The CW.

Multiple networks

Philadelphia's WCAU-TV had been a CBS owned-and-operated station starting in 1958. However, after CBS announced its alliance with Westinghouse Broadcasting in 1995, the network chose to affiliate with Westinghouse's KYW-TV, Philadelphia's longtime NBC affiliate. After a bidding war, WCAU was sold to NBC. KYW became a CBS owned-and-operated station after Westinghouse's merger with CBS a few months later.
As part of the same deal, NBC in turn transferred its own O&O stations in Denver and Salt Lake City to Westinghouse/CBS, and those stations became CBS O&Os after Westinghouse merged with CBS. NBC and CBS also swapped transmitting facilities in Miami between the then-weaker CBS-owned WCIX and the then-stronger NBC-owned WTVJ.

Until 2018, TBN never sold any of its full-power television stations, though several translator stations have been sold off since the digital transition to other parties for either spectrum speculation, to become translators of other commercial stations, or in the case of W41BN in Dothan, Alabama, to become an affiliate of one of the major broadcast networks; in that case W41BN is now WRGX-LD, the market's NBC affiliate under the ownership of Gray Television. Several other translator stations have been taken off-the-air completely as TBN's distribution has become concentrated on pay television and IPTV distribution, due to the prohibitive costs of upgrading the entire network's translator system to digital.
In September 2018, TBN completed the sale of full-power station WDLI-TV to Ion Media, with whom it had entered into a channel sharing agreement in March 2018 involving Ion's WVPX-TV; Ion chose to exploit WDLI-TV's full-market cable and satellite coverage for carriage of Ion Life/Plus in Cleveland, formerly carried on WVPX-DT3. The same transaction resulted in the sale of WKOI-TV to Ion Media which allowed dual-market carriage of Ion Television in Dayton and Cincinnati after TBN entered into a channel sharing agreement with WDTN, WSFJ-TV's channel share with Daystar's WCLL-CD resulted in full-market coverage of Ion Plus in the Columbus market, and the same arrangement with Ion's WIPX-TV resulted in WCLJ becoming a primary Ion Plus station for the Indianapolis market.
