Broadcast network

A terrestrial network (or broadcast network in the United States) is a group of radio stations, television stations, or other electronic media outlets, that form an agreement to air, or broadcast, content from a centralized source.[1] For example, PBS (U.S.) and BBC (U.K.) are TV networks that provide programming for local terrestrial television station affiliates to air using signals that can be picked up by the home television sets of local viewers.[1] Large networks are mostly national, but there is also a Global Television Network.

Streaming media, Internet radio, and webcasting are sometimes considered forms of broadcasting despite the lack of terrestrial stations; its practitioners may also be called "broadcasters" or even "broadcast networks".

Broadcasting chains (original)
Original major radio broadcasting networks in the United States

American networks

AT&T's "WEAF Chain"

Following the introduction of radio broadcasting in the early 1920s, the American Telephone and Telegraph Company (AT&T) developed the first radio network, linking together individual stations with specially prepared long-distance telephone lines in what at the time was called a "chain". The key station was AT&T's WEAF (now WFAN) in New York City. The network featured a variety of regularly scheduled programs which included sponsorships (at the time not called advertising but "toll broadcasting").[2]

From the beginning, AT&T planned to eventually expand nationwide, so that national companies would be able reach large portions of the nation with their brand names and slogans in an efficient manner. At first the network's expansion was slow. In 1924, the Eveready Hour was broadcast over 12 stations, primarily located in the U.S. Northeast. Eveready Hour was the first commercially sponsored variety show in the history of broadcasting. By 1925, AT&T had linked together 26 stations in its network.[3]

AT&T eventually decided to concentrate on its most profitable business, telephones, and in 1926 sold its broadcasting interests to the Radio Corporation of America (RCA). RCA's purchase included an agreement to lease AT&T phone lines.[3]

RCA's "WJZ Chain"

In 1922 the Radio Corporation of America (RCA) followed AT&T's network model lead, and formed a small competing network centered on its New York City station, WJZ (now WABC). However, conflict resulted as RCA had a limited ability to lease lines from AT&T, and often had to use telegraph lines to connect stations, which had inferior acoustical properties.[3]


After acquiring WEAF and AT&T's network assets in 1926, RCA created the National Broadcasting Company (NBC) and reorganized the WEAF chain (with WGR, WTIC, WTAG, WEEI, WJAR, WZAN, WFI-WLIT, WCAE, WRC, WTAM, WSAI, WWJ, WGN, WOC, KSD, WDAF, WCCO) as the NBC Red network, and the WJZ chain as the NBC Blue network (with WBZ, WBZA, KYW, KDKA). (One explanation for the color designations is that they reflected the red and blue push pins used on a map that AT&T originally used to designate the affiliated stations on the two networks.)[2]

On 23 December 1928, NBC instituted the first permanent transcontinental network. As of September 1938, when there were 154 NBC outlets; 23 composed the basic Red network and 24 composed the basic Blue network. Supplementing these basic networks were 107 stations, of which one was available only to the basic Red network, six were available only to the basic Blue network, and the remainder available to either. NBC also had a chain of shortwave stations, called the "NBC White Network", in the 1930s.

In 1941, the Federal Communication Commission's (FCC) Report on Chain Broadcasting[4] reviewed the alleged monopolistic practices of the radio networks. The FCC was concerned NBC Red and NBC Blue were anti-competitive. Because the FCC did not have the power to directly regulate networks, it decided to enact regulations affecting the stations, and adopted standards intended to force NBC to relinquish one of its networks. In 1943, the Supreme Court upheld the FCC's power to enforce its chain broadcasting regulations.[5][6] As a consequence, NBC Blue was sold to Edward Noble who later named it the American Broadcasting Company (ABC).[5] After NBC Blue was divested the remaining NBC Red network was renamed the NBC Radio Network.[2]


In 1927, United Independent Broadcasters, Inc., supported by the Columbia Phonograph Record Company, started a new network of 16 stations (WOR New York, WFBL Syracuse, WMAK Buffalo-Lockport, WNAC Boston, WEAN Providence, WCAU Philadelphia, WJAS Pittsburgh, WCAO Baltimore, WADC Akron, WAIU Columbus, WKRC Cincinnati, WGHP Detroit, WOWO Fort Wayne, WMAQ Chicago, KMOX St. Louis, KOIL Council Bluffs) named the Columbia Phonographic Broadcasting System.

In 1928 William S. Paley assumed control of the network, which under his leadership focused on entertainment programming, news, and news affiliation. He quickly turned the failing company around, which was named Columbia Broadcasting System, Inc. (CBS) in 1929. By the end of 1938 there were 113 CBS outlets. Regional networks on CBS also existed in various parts of the country.[3]

CBS later hired Edward R. Murrow who is credited with boosting ratings dramatically. Murrow and CBS covered the war in Europe while Adolf Hitler was in power. NBC and ABC withdrew from the war for safety reasons. As a result of taking the risk, CBS's ratings skyrocketed.[7]


In 1945, the NBC Blue network was sold to Edward John Noble, who later renamed it American Broadcasting Company (ABC).[5] By the mid-1940s broadcasting had become a big Three television networks battle. ABC almost went bankrupt and in 1951 Leonard Goldenson and United Paramount Theaters bought the network for $25 million. In 1964, ABC won the ratings race in the fifty largest U.S. markets. In the 1970–71 season, ABC ranked #1 in the Nielsen ratings with a medical drama called Marcus Welby, M.D.,[8] the first ABC television show to top the list.


In 1929, a group of four radio stations in the major markets of New York City, Chicago, Cincinnati, and Detroit organized into a loose confederation known as the Quality Network. In 1934 this was reorganized as the Mutual Broadcasting System. The network was organized with the members contracting for telephone-line transmission facilities and agreeing to collectively enter into contracts with advertisers for their networked shows.

Westwood One News

Radio news network launched on January 1, 2015 and operated by Westwood One through its parent company Cumulus Media.[9]

Canadian national networks

The first network in Canada was CNR Radio starting in 1923. The first regularly scheduled coast-to-coast network program produced by CN Radio was broadcast on 27 December 1928. By 1930, the network consisted of 27 stations.

Alsco 300 (Bristol)

The Alsco 300 is a NASCAR Xfinity Series stock car race that takes place at Bristol Motor Speedway, the first of two Bristol races on the schedule.

The first Busch Series race at Bristol was 150 laps, and was won by Phil Parsons in 1982. The race was not held in 1984. The race has increased in length several times since then. It was lengthened to 200 laps in 1985, 250 laps in 1990, and 300 laps in 2006.

In 2016, the Bristol format was changed to include two 50-lap heat races and a 200-lap feature for a total of 300 laps, as part of the Xfinity Dash 4 Cash program. In 2017 that format did not return and instead reverted to its 300-lap distance with the new stage format. Stages 1 and 2 will be 85 laps each, with stage 3 being the final 130 laps.

The race has been put on broadcast network television to heighten the popularity of the circuit; Fox's broadcasts of Bristol's Food City 500 were the first time broadcast network television covered the event; the races between 2004 and 2006 aired as Nationwide/Cup Fox doubleheaders. Beginning in 2007 the event aired on ABC as part of ESPN2's new Nationwide Series television package, as ESPN2 had committed to the NCAA Women's Basketball Tournament at the time.

Bible Broadcasting Network

The Bible Broadcasting Network (BBN) is a listener-supported global Christian radio network staffed and headquartered in Charlotte, North Carolina. The programming consists of 50% outside ministries, 30% music and 20% BBN-produced programs. The network was founded in 1968 by its then-president, Lowell Davey (1933–2017). Programming content includes traditional Christian music, prayer times, children's programs, Bible teaching, teen programs, and family guidance programs. The network was born out of Davey's failed offer to buy a radio station in Norfolk, Virginia. The company was incorporated and on March 28, 1969, bought bankrupt WYFI and began broadcasting on October 2, 1971, at 5 p.m.The station plays all-traditional Christian music, including vocalists, choirs, and instrumentalists. BBN's mission statement is "to get the Word of God into the hearts and minds of as many people as possible using the most efficient means." Doctrinally, the programming is conservative evangelical in approach. BBN also avoids programming geared towards "signs and wonders", "charismatic" theology, and "prosperity theology".

Cable television

Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fiber-optic cables. This contrasts with broadcast television (also known as terrestrial television), in which the television signal is transmitted over the air by radio waves and received by a television antenna attached to the television; or satellite television, in which the television signal is transmitted by a communications satellite orbiting the Earth and received by a satellite dish on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation.

A "cable channel" (sometimes known as a "cable network") is a television network available via cable television. When available through satellite television, including direct broadcast satellite providers such as DirecTV, Dish Network and Sky, as well as via IPTV providers such as Verizon FIOS and AT&T U-verse is referred to as a "satellite channel". Alternative terms include "non-broadcast channel" or "programming service", the latter being mainly used in legal contexts. Examples of cable/satellite channels/cable networks available in many countries are HBO, Cinemax, MTV, Cartoon Network, AXN, E!, FX, Discovery Channel, Canal+, Eurosport, Fox Sports, Disney Channel, Nickelodeon, CNN International, and ESPN.

The abbreviation CATV is often used for cable television. It originally stood for Community Access Television or Community Antenna Television, from cable television's origins in 1948. In areas where over-the-air TV reception was limited by distance from transmitters or mountainous terrain, large "community antennas" were constructed, and cable was run from them to individual homes. The origins of cable broadcasting for radio are even older as radio programming was distributed by cable in some European cities as far back as 1924.

Court TV

Court TV is a current digital broadcast network and former American cable television channel. It was originally launched in 1991 with a focus on crime-themed programs such as true crime documentary series, legal dramas, and coverage of prominent criminal cases. In 2008, the original cable channel became TruTV. The channel relaunched on May 8, 2019 as a digital broadcast television network that is owned by Katz Broadcasting, a subsidiary of the E. W. Scripps Company.


Digital Video Broadcasting – Satellite (DVB-S) is the original DVB standard for Satellite Television and dates from 1995, in its first release, while development lasted from 1993 to 1997. The first commercial application was by Galaxy in Australia, enabling digitally broadcast, satellite-delivered Television to the public.

It is used via satellites serving every continent of the world. DVB-S is used in both Multiple Channel Per Carrier (MCPC) and Single channel per carrier modes for Broadcast Network feeds as well as for direct-broadcast satellite services like Sky (UK & Ireland) via Astra in Europe, Dish Network and Globecast in the U.S. and Bell TV in Canada.

While the actual DVB-S standard only specifies physical link characteristics and framing, the overlaid transport stream delivered by DVB-S is mandated as MPEG-2, known as MPEG transport stream (MPEG-TS).

Some amateur television repeaters also use this mode in the 1.2 GHz amateur band.

Interstate matches in Australian rules football

Australian rules football matches between teams representing Australian colonies, states and territories have been held since 1879. For most of the 20th century, the absence of a national club competition and international matches meant that football games between state representative teams were regarded with great importance. Football historian John Devaney has argued that: "some of the state of origin contests which took place during the 1980s constituted arguably the finest expositions of the game ever seen".Until 1976, interstate Australian rules football games were played by teams representing the major football leagues or organisations. From 1977 to 1999, players were generally selected under State of Origin selection rules and they were chosen mostly from the Australian Football League (AFL). Since 2000, all matches have been between teams representing the second-tier state or territorial leagues. Players from the AFL no longer take part in interstate matches.

The matches have mostly been held on a stand-alone basis. However, an Australian Football Carnival, a national championship series, held in either one or two cities, took place between 1908 and 1993, usually at three year intervals. Teams which have taken part have included Victoria, South Australia, Western Australia, Tasmania, New South Wales, Queensland, Northern Territory, Australian Capital Territory and an Australian Amateurs team. Between 1937 and 1988 the player judged the best at each of these carnivals was awarded the Tassie Medal.

Between 1953 and 1988, the selection of All Australian Teams was based on players performance during Australian Football Carnivals, and the team was named after each carnival concluded.

Opinion journalism

Opinion journalism is journalism that makes no claim of objectivity. Although distinguished from advocacy journalism in several ways, both forms feature a subjective viewpoint, usually with some social or political purpose. Common examples include newspaper columns, editorials, op-eds, editorial cartoons, and punditry.Unlike advocacy journalism, opinion journalism has a reduced focus on facts or research and its perspective is often of a more personalized variety. Its product may be only one component of a generally objective news outlet, rather than the dominant feature of an entire publication or broadcast network.There are a number of journalistic genres that are opinion-based. Among them, for example, there is Gonzo journalism and New Journalism.

There is also an international service, TCT World, now broadcasting in over 170 nations, which covers every continent except South America. TCT World's schedule is also around-the-clock. TCT World, like their three over-the-air television feeds, can also be viewed online via their live streaming video feed on their website archived videos of recent

TCT Today and TCT Alive programs are available for viewing on their website.

TCT is also available on DirecTV on channel 377, and on Sky Angel channel 133.

The network was founded in May 1977 by Garth and Tina Coonce, who are still both involved in TCT today, as well as hosts of their flagship program, which, is TCT Today.

From the mid-1980s to 2007, TCT was an affiliate of the Trinity Broadcasting Network. The network currently maintains a relationship with the Christian Broadcasting Network, airing that network's flagship program The 700 Club twice daily as well as CBN's nightly newscast.

From 2011 to 2013, TCT operated a Spanish-language subchannel which was available both on line and over the air on TCT stations called La Fuente.

In June 2018, TCT ended local operations at all of its owned-and-operated stations, consolidating all of its stations into a single national feed. The change came after the Federal Communications Commission lifted its Main Studio Rule, which had required broadcast stations to have a local studio. All local employees were laid off, and studio sites were placed up for sale. TCT stated that the change was made to free up capital to improve the network's programming, moving away from the straight televangelism-dominated lineup it had previously maintained (television remains the network's core programming) and adding more Christian films.
