In the
United States, the practice of duopolies has been frowned upon when using public airwaves, on the premise that it gives too much influence to one company. However, rules governing radio stations are less restrictive than those for television, allowing as many as eight radio stations under common ownership in the largest U.S.
media markets. Ownership of television stations with overlapping coverage areas was normally not allowed in the United States prior to 2002, even those that were not duopolies under the present legal definition, by way of being located in separate albeit adjacent markets; this required broadcasters to apply for cross-ownership waivers in some cases to retain full-power stations based in adjacent markets.
Non-commercial educational broadcasters, mainly those that were
members of the Public Broadcasting Service (
PBS), were the only licensees allowed to sign-on or acquire a second television station that did not repeat the parent station's signal in the same market where they already owned a station (some of these acquired stations were originally licensed as commercial outlets). On August 5, 1999, the
Federal Communications Commission voted 4–1 to allow common ownership of two television stations within a single market by one company, so long as eight unique station owners remain in the market once the duopoly is formed, and the four highest-rated stations (based on local monthly viewership reports for the market) remain under separate ownership. The FCC only requires the severance of an existing duopoly in which a once lower-rated station falls within the ratings criteria that prohibits such ownership over time if an ownership transaction is under review (such as a piecemeal or group sale of stations, or necessary license transfers during an ownership transaction involving the stations' existing owner); a company is required to sell one of the stations in the duopoly to another licensee if it is no longer compliant with one or both provisions. Currently, an entity is permitted to own up to two television stations in the same media market if either the service areas of the stations do not overlap, or at least one of the stations is not rated among the top four rated stations in the media market. There is no limit on the number of television stations a single entity may own as long as the stations group collectively reaches no more than 39% of U.S. households. Once a duopoly is formed, the acquiring company takes over the operations of its new property. The operations of the two stations are usually consolidated into one facility, depending on the size and age of the facility chosen to house their operations. Since the stations involved in the duopoly are not restricted by FCC law from consolidating their operations, duplicative jobs at one of the stations are often terminated as the consolidation takes effect. News departments are also often consolidated into a singular operation, with anchoring and reporting staffs from the respective stations often being folded into one unit, subject to hiring determinations made by management; anchors and reporters are usually shared between the two stations, though in some cases, certain anchors may be employed to appear only on each station's own newscasts. In some cases (like with
WHDH and
WLVI in
Boston, Massachusetts, when the former's owner
Sunbeam Television formed a duopoly with WLVI after purchasing the station from
Tribune Broadcasting in 2006), the junior partner's news department is shut down completely, with the senior partner subsequently taking over production of its news content using only their existing staff. In many cases, news programming on a junior partner is structured to avoid direct competition with a senior partner affiliate of either
ABC,
NBC or
CBS (one notable exception involves
WTTV and
WXIN in
Indianapolis, which carry competing morning and evening newscasts as Tribune Broadcasting opted to launch a separate slate of newscasts for WTTV when it became a CBS affiliate in January 2015, rather than shift those seen on sister
Fox affiliate WXIN to the station; WXIN and WTTV largely maintain their own anchors, but share a news department and most reporting staff). This situation is uncommon in duopolies involving only
Big Three affiliates, as stations affiliated with those networks are more inclined to carry newscasts in overlapping time periods in order to fulfill local programming requirements included in affiliation agreements. Certain
syndicated programs are also shared between the stations, in the form of either same-day repeat airings of programs seen on the one which holds primary rights or separated runs of programs that air on each station, although each station maintains separate syndication inventories as well. The junior partner, unless it is affiliated with a major network, may also be used to carry network (and occasionally, first-run syndicated) programs that the senior partner is unable to broadcast because of long-form
breaking news or
severe weather coverage or a locally produced
special airing in a scheduled program's normal timeslot, or in the case of certain non-prime time network programs, because the senior partner chooses not to carry it on its regular schedule to carry other scheduled programming. Although the FCC bars common ownership of any of the four major broadcast networks (ABC, NBC, CBS and Fox), it does not prohibit duopolies involving stations affiliated individually with any two of them, unless both are among the four highest-rated in the market at the time of a sale. As such, several Big Four duopolies exist based on certain market conditions that originally allowed them to be formed under the criteria (such as a company having acquired one of the major network stations as a low-rated affiliate of a smaller network prior to an affiliation switch or the ratings of a non-English station placing among the top four over a Big Four network affiliate). While most duopolies are made up of a senior partner that is affiliated with one of the four major networks and an affiliate of a minor network (such as
The CW and
MyNetworkTV) or an
independent station as the junior partner, those in which both stations are major network affiliates typically involve a Fox station (which serves as the junior partner in all but a few instances) and an ABC, CBS or NBC affiliate, with some limited arrangements where two Big Three affiliates are jointly owned or managed. One of the few markets where two major network duopolies exist in some form is
Jacksonville, Florida, where two companies once owned the licenses of the Big Four stations they respectively controlled. In 2000, the
Gannett Company, owner of NBC affiliate
WTLV, purchased ABC affiliate
WJXX, which had struggled in the local ratings since its sign-on in February 1997 (when it took the ABC affiliation from
WJKS through a
group affiliation deal with the
Allbritton Communications Company) due to its status as a relatively new station and issues with signal interference from PBS station
WJCT on its
Mediacom cable channel slot. The following year,
Clear Channel Communications created a legal duopoly involving its existing Fox affiliate WAWS (now
WFOX-TV) and WTEV-TV (now
WJAX-TV), a
UPN affiliate that it had been managing under a local marketing agreement since 1994; WTEV's viewership gradually rose after it became a CBS affiliate in July 2002, putting it in the top four threshold with WAWS, resulting in
Newport Television – upon purchasing the Clear Channel television group in 2007 – restructuring the operation as a virtual duopoly by selling WTEV to shell licensee High Plains Broadcasting (WFOX and WJAX are now respectively owned by the
Cox Media Group and Bayshore Television, LLC, but remain under common management through JSA/SSA in which WJAX is the junior partner). The use of
digital subchannels has been termed an "instant duopoly," because of the ease by which a single digital station can deliver multiple channels of programming from different networks at the same time. One station can carry four or more
standard definition digital channels; multiple
high definition feeds typically require too large a bitrate size to be carried on different subchannels of the same station simultaneously without loss of image quality.
2017 changes On November 20, 2017, in its reconsideration order to the Quadrennial Regulatory Review regarding media ownership, the FCC voted to make significant changes, particularly to local television ownership. In its decision, the FCC eliminated the "Eight-Voices Test" requirement, allowing media companies to form duopolies regardless of the number of full-powered stations licensed to each market. It also allows media companies to form duopolies comprising two of the four highest-rated stations in a particular market, provided that companies can prove to the FCC that the transaction "would serve the public interest, convenience, and necessity," and that it is necessary "due to specific circumstances in a local market or with respect to a specific transaction on a case-by-case basis." The said changes were put into practice on two occasions: • On May 1, 2018,
KDLT-TV owner
Gray Television announced that it is buying
KSFY-TV from
Red River Broadcasting, despite both stations ranking within the four highest-rated stations in the
Sioux Falls market. Gray obtained a waiver from the FCC, citing that KSFY would be in a stronger position if its resources are to be combined with KDLT, and that a duopoly for the said stations would fulfill "a dire need for an effective competitor" in the market, given that rival station
KELO-TV ranks higher in the ratings. The sale was approved by the FCC on September 24, 2019, and was completed the following day. • On May 8, 2023,
KSWB-TV owner
Nexstar Media Group announced that it is buying independent station
KUSI-TV for $35 million. The transaction would create the first legal duopoly in
San Diego – the largest US market that was ineligible to do so under the 1999 "Eight-Voices Test" set by the FCC, owing to its proximity with stations in
Tijuana along the international border with Mexico. The transaction was completed on August 31.
Virtual duopolies Some broadcasting companies have used
loopholes to establish duopolies in smaller markets by way of a
local marketing agreement, shared services agreement or joint sales agreement; where a station effectively
brokers its entire airtime to the owner of another station in the market, which becomes responsible for handling its programming and advertising sales – and in effect, operations. These are termed as "virtual duopolies" as the station's license is held by one company, while its operations are handled by another. Through a 2014 FCC ruling, joint sales agreements in which the senior partner sells a minimum of 15% of the advertising time for its junior partner are counted toward ownership caps. Some larger broadcasting companies have controversially built business models around the practice, by funding the acquisition of stations by what are effectively
shill companies or
shell corporations; for example,
Sinclair Broadcast Group operates the stations of
Cunningham Broadcasting and
Deerfield Media under LMAs, JSAs, or SSAs. Nearly all of Cunningham's stock is held by trusts in the name of Sinclair's founders and owners, the Smith family. Similarly,
Nexstar Media Group funds the purchase of stations by
Mission Broadcasting and
Vaughan Media, which forms duopolies with their stations through shared services agreements with a Nexstar station. In some cases, the senior partner may acquire a station's physical assets and intellectual property (such as the station's facilities and programming rights), but spin off the license itself to a shell corporation and enter into an agreement to operate the station, making it the
de facto owner, but not the legal owner. Following the purchase, the station's operations and programming are often merged into that of its new parent station. Similarly, a company that acquires an existing legal duopoly that is no longer complies with FCC rules on duopoly ownership may spin off the junior partner station's license to a shell, rather than sell one of the stations to a licensee that would also assume operational responsibilities, allowing the restructured duopoly to remain under common operation through a resulting management agreement. In some cases, the use of an adjacent-market
city of license has been used on a secondary station to avoid a limit on the number of stations controlled by the same broadcaster in the same market. Occasionally, those arrangements cross international borders. For instance,
radio station WLYK in
Cape Vincent, New York in the United States is operated from the Canadian studios of
Kingston, Ontario's
CIKR-FM, a broadcaster already at the two-station limit in its own market, under an LMA. Broadcasters such as
Entravision have often entered into local marketing agreements with Mexican border stations (such as
Tecate's
XHDTV-TDT for content directed at
San Diego).
Failing station waivers It is also possible to obtain a "failing station waiver," which can exempt a broadcaster from some portion of the existing restrictions on common ownership in order to acquire and operate a station which otherwise would be economically non-viable or would be forced to
cease operations. Requests for failing station waivers have historically met with variable reception; in general, the FCC views requests favorably if: • The failing station consistently received less than 4% of all local all-day audience share; • the station is in poor financial condition, normally operating at a loss for at least the previous three years; • the merger will produce public interest benefits, and; • the in-market buyer is the only suitable candidate as a sale to an out-of-market buyer would result in an artificially depressed price. Waivers under these criteria were granted to sell
WASV-TV in
Asheville to
Media General, owner of CBS affiliate
WSPA-TV in that market, and
KWBA in
Tucson to the
Journal Broadcast Group, owner of that market's ABC affiliate
KGUN-TV. A similar waiver was refused to
KNIN-TV in
Boise as the station, a CW affiliate at the time the waiver application was filed, appeared to have reasonable prospects of financial break-even without a takeover by Journal-owned ABC affiliate
KIVI-TV; that decision was subsequently appealed, with the waiver being granted upon further review (Journal Broadcast Group would eventually be required to sell KNIN in 2014, as the station's financial condition improved enough in its post-2011 existence as a Fox affiliate to make it unsuitable for the
E. W. Scripps Company – which was in the process of purchasing Journal's broadcasting unit in a deal in which Journal simultaneously merged with Scripps' publishing unit – to acquire it under a renewed waiver, in addition to the fact that it could not acquire it legally as the market had fewer than eight unique owners).
Low-power TV stations Low-power and
Class A television stations are not subject to ownership caps in the United States, as their broadcast signals do not reach as many homes as full-power stations. In areas with high
cable television penetration, this distinction is essentially meaningless. LPTV stations were also exempt from
digital television transition requirements imposed on full-service broadcasters upon the
June 2009 digital conversion. As such, low-power stations can also be formed to create duopolies; for instance,
Weigel Broadcasting maintains triopolies in three markets surrounding the southern part of
Lake Michigan (
Chicago, Illinois;
Milwaukee, Wisconsin; and
South Bend, Indiana) using a combination of full-power and low-power television stations. In Chicago, it maintains one full-power signal (CW-affiliated station
WCIU-TV) and two low-power stations (
MeTV flagship station
WWME-CD and independent station
WMEU-CD). In Milwaukee, Weigel has two full-power stations (CBS affiliate
WDJT-TV and full-power independent station
WMLW-TV) and two low-power stations (MeTV station
WBME-CD and
Telemundo affiliate
WYTU-LD, the latter stations of which use subchannels of WDJT as its main conduit for full-power carriage). Weigel also takes advantage of digital subchannel broadcasting heavily in addition to MeTV, it also owns
MeTV+,
Heroes & Icons,
Start TV,
Decades,
Movies!, and
Story Television, all of which air on its stations, in addition to other station groups; the company had also previously executed time share agreements on other subchannels with ethnic broadcasters, and in Milwaukee, a local real estate agency to air programming. A similar situation exists in
Lima, Ohio, where
Block Communications controls a quadropoly of stations owned by itself (
WLIO, a full-powered NBC affiliate which also carries Fox and MyNetworkTV on a digital subchannel) and low-power stations owned by West Central Ohio Broadcasting, Inc. (which owns ABC affiliate
WPNM-LD/
WOHL-CD, and CBS affiliate
WAMS-LD) under an LMA. One of the latter company's heads, Allan J. Block, is the chairman of Block Communications. The group is the sole over-air provider of secular network television programming in the Lima market, though area cable systems also carry out-of-market affiliates from
Toledo,
Columbus and
Dayton. (All of the Block owned or operated stations have a pending sale to
Gray Media expected to close in the fourth quarter of 2025).
Radio stations As mentioned above, current FCC rules limit the number of radio stations a single entity may own in a certain market. As of May 2020, these are the limitations on radio ownership in a certain market, according to the FCC website: • In a radio market with 45 or more stations, an entity may own up to eight radio stations, no more than five of which may be on the same band (AM or FM). • In a radio market with between 30 and 44 stations, up to seven stations are allowed under common ownership, no more than four of which could be on AM or FM. • In a radio market with between 15 and 29 stations, an entity may own up to six stations, no more than four of which may be on the same band. • In a radio market with 14 or fewer radio stations, an entity may own up to five radio stations, of which no more than three of which may be on the same band, as long as the entity does not own more than half of the stations in that market. Unlike television, there is no limit on the percentage of the population to that an entity may reach. ==Canada==
