Television network

Not to be confused with television channel or television station.

A television network is a telecommunications network for distribution of television program content, whereby a central operation provides programming to many television stations or pay TV providers. Until the mid-1980s, television programming in most countries of the world was dominated by a small number of broadcast networks. Many early television networks (e.g. the BBC, NBC or CBS) evolved from earlier radio networks.

In countries where most networks broadcast identical, centrally originated content to all their stations and where most individual TV transmitters therefore operate only as large "repeater stations", the terms "television network", "television channel" (a numeric identifier or radio frequency), and "television station" have become mostly interchangeable in everyday language, with professionals in TV-related occupations continuing to make a difference between them. Within the industry, a tiering is sometimes created among groups of networks based on whether their programming is simultaneously originated from a central point, and whether the network master control has the technical and administrative capability to take-over the programming of their affiliates in real-time when it deems this necessary — the most common example being national breaking news events.

In North America in particular, many television networks available via cable and satellite television are branded as "channels" because they are somewhat different than traditional networks in the sense defined above, as they are singular operations – they have no affiliates or component stations, but instead are distributed to the public via cable headends or direct-broadcast satellite companies. Such networks are commonly referred to by terms such as "specialty channels" in Canada or "cable networks" in the U.S.

A network may or may not produce all of its own programming. If not, production houses such as Warner Bros. and Sony Pictures can distribute their content to the different networks, and it is common that a certain production house may have programmes on two or more rival networks. Similarly, some networks may import television programmes from other countries, or use archival programming to help complement their schedules.

Some stations or headends have the capability to interrupt the network through the local insertion of TV commercials, station IDs, and emergency alerts. Others completely break away from the network for their own programming, known as regional variation. This is common where small networks are members of larger networks.

As with individual stations and headends, modern centralcasting network operations centers usually use broadcast automation to handle most tasks. These systems are not only used for Broadcast programming and for video server playout, but use exact atomic time from GPS or other sources to maintain perfect synchronization with upstream and downstream systems, so that programming appears seamless to audience viewers.

Global

A major international television network is the British Broadcasting Corporation, or BBC which is perhaps well known for its news agency BBC News. Owned by the Crown, the BBC operates primarily in the United Kingdom. It is funded by the television licence paid by British residents that watch broadcast TV and as a result, no commercial advertising appears on their networks. Outside of the UK, advertising is shown because the licence fee only applies to the BBC's British operations. 23,000 people worldwide are employed by the BBC and it's subsidiary, BBC Worldwide.

United States

Television in the United States has long been dominated by the Big Three television networks, ABC, CBS and NBC, but Fox, launched in 1986, has gained prominence and is now considered as part of the "Big Four." The Big Three provide a significant amount of television programs to each of their affiliates, including newscasts, prime-time, daytime television and sports television, but still have periods each day when each affiliate can air local programming, such as local news or syndicated programmes. Since the creation of Fox, the number of American television networks has grown, but the amount of programming they provide is often much less: for example, The CW Television Network only broadcasts for ten hours each week, leaving its affiliates free to broadcast a large amount of syndicated programming. Other networks are dedicated to specialist programmes, such as religious broadcasting or services in languages other than English, especially in Spanish.

The largest television network in the United States, however, is the Public Broadcasting Service (PBS), a non-profit, non-commercial educational, publicly owned service. In comparison to the commercial television networks, there is no central unified arm of broadcast programming, meaning that each PBS affiliate has a significant amount of freedom to schedule television shows as it sees fit.

There are also regional state networks in the U.S., mostly for public television which refers to a miniature television network serving an entire state or multiple states. State Networks are common with stations aligned with the PBS, however there are a few state networks that are affiliated with a Commercial broadcasting television network. These public television may also carry separate digital networks. For example, all Georgia Public Broadcasting stations simulcast, and carry mostly PBS and some GPB TV programs on one channel, PBS Kids on another channel branded as GPB Kids, and PBS World and other PBS and GPB programming on a third channel branded GPB Knowledge. Besides Georgia, several other U.S. states have statewide or regional PBS state networks.

With the digital terrestrial television and the mandated DTV transition in the United States, several television networks have been created specifically to be transmitted on the digital subchannels of TV stations. These include Ion Life (which is almost always paired with Ion Television as most of the stations are network-owned), and ThisTV (which is carried on an assortment of unrelated stations).

Providers of pay TV generally on cable television pay the networks a certain amount per subscriber (the highest charge being for ESPN). Direct-broadcast satellite company can sell local television commercials, in which case there may be revenue sharing. Networks that consist entirely of home shopping or infomercials may instead pay the station or cable/satellite provider, which is known as brokered programming. This is especially common with low-power TV stations, and now even more so for the ones that are using this income to make the forced conversion to digital, which in turn provides them with several extra channels to transmit different program sources on.

History

Television broadcasting in the United States was heavily influenced by radio, a precursor to television. Early individual experimental radio stations in the United States began limited operations in the 1910s. In November 1920, in Pittsburgh, Westinghouse launched "the world's first commercially licensed radio station", KDKA.^[1] Other companies built early radio stations in Detroit, Boston, New York City, and other areas. Radio stations received permission to transmit through broadcast licenses obtained through the Federal Radio Commission (FRC), a government entity created in 1926 to regulate the radio industry. With few exceptions, radio stations east of the Mississippi River received official call signs beginning with the letter W; those west of the Mississippi a K. The amount of programs these early stations aired was often limited, in part due to the expense of program creation. The idea of a network system which would distribute programming to many stations simultaneously, saving each station the expense of creating all of its own programs and expanding the total coverage beyond the limits of a single broadcast signal, was devised.

NBC set up the first permanent coast-to-coast radio network in the United States by 1928, using dedicated telephone line technology. The network physically linked individual radio stations, nearly all of which were independent radio owned and operated station, in a vast chain, NBC's audio signal thus transmitted from station to station to listeners across the United States. Other companies, including CBS and Mutual, soon followed suit, each network signing hundreds of individual stations on as affiliates: stations which agreed to broadcast one network's programs.

As radio prospered throughout the 1920s and 1930s, experimental television stations, which broadcast both an audio and a video signal, began sporadic broadcasts. Experimental television station broadcast license were often granted to experienced radio broadcasters, and thus advances in television technology closely followed breakthroughs in radio technology. As interest in television grew, and as early television stations began regular broadcasts, the idea of networking television signals (sending one station's video and audio signal to outlying stations) was born. However, the signal from an electronic television system, containing much more information than a radio signal (6 MHz), required a broadband transmission medium. Transmission by a nationwide series of radio relay towers would be possible but extremely expensive.

Researchers at the AT&T subsidiary Bell Telephone Laboratories patented coaxial cable in 1929, primarily as a telephone improvement device. Its high capacity (transmitting 240 telephone calls simultaneously) also made it ideal for long-distance television transmission, where it could handle a frequency band of 1 megahertz.^[2] German television first demonstrated such an application in 1936 by relaying televised telephone calls from Berlin to Leipzig, 180 km (110 mi) away, by cable.^[3]

AT&T laid the first L-carrier coaxial cable between New York and Philadelphia, with automatic signal booster stations every 10 miles (16 km), and in 1937 they experimented with transmitting televised motion pictures over the line.^[4] Bell Labs gave demonstrations of the New York–Philadelphia television link in 1940–1941. AT&T used the coaxial link to transmit the Republican national convention in June 1940 from Philadelphia to New York City, where it was televised to a few hundred receivers over the NBC station.^[5]

NBC had earlier demonstrated an inter-city television broadcast on February 1, 1940, from its station in New York City to another in Schenectady, New York by General Electric relay antennas, and began transmitting some programs on an irregular basis to Philadelphia and Schenectady in 1941. Wartime priorities suspended the manufacture of television and radio equipment for civilian use from April 1, 1942 to October 1, 1945, temporarily shutting down expansion of television networking. However, in 1944 a short film, "Patrolling the Ether", was broadcast simultaneously over three stations as an experiment.

The DuMont Television Network in 1949. DuMont's network of stations stretched from Boston to St. Louis. These stations were linked together via AT&T's coaxial cable feed, allowing the network to broadcast live television programming to all the stations at the same time. Stations not yet connected received kinescope recordings via physical delivery.

AT&T made its first postwar addition in February 1946, with the completion of a 225-mile (362 km) cable between New York City and Washington, D.C., although a blurry demonstration broadcast showed that it would not be in regular use for several months. The DuMont Television Network, which had begun experimental broadcasts before the war, launched what Newsweek called "the country's first permanent commercial television network" on August 15, 1946, connecting New York with Washington.^[6] Not to be outdone, NBC launched what it called "the world's first regularly operating television network" on June 27, 1947, serving New York, Philadelphia, Schenectady and Washington.^[7] Baltimore and Boston were added to the NBC television network in late 1947. DuMont and NBC would be joined by CBS and ABC in 1948.

In the 1940s, the term "chain broadcasting" was used when discussing network broadcasts,^[8] as the television stations were linked together in long chains along the East Coast. But as the television networks expanded westward, the interconnected television stations formed great television networks of connected affiliate television stations. In January 1949, with the signon of DuMont's WDTV in Pittsburgh, the midwest and east-coast networks were finally connected by coaxial cable (with WDTV showing the best shows of all four networks)[1]. By 1951, the four networks stretched from coast to coast, carried on the new microwave radio relay network of AT&T Long Lines. Only a few local TV stations remained independent of the networks.

Originally, each of the four major television networks only broadcast a few hours of programs a week to their affiliate stations, mostly between the hours of 7 and 10 PM when most viewers were watching television. Most of a television station's programs were still locally-produced. As the networks increased the number of programs they aired, however, officials at the Federal Communications Commission grew concerned that local television might disappear altogether. Eventually, the federal regulator enacted the Prime Time Access Rule, which restricted the amount of time that the networks could air programs; officials hoped the rules would foster the development of quality local programs, but in practice, most local stations did not want to bear the burden of producing many of their own programs, and instead chose to purchase programs from independent producers. Sales of television programs to individual local stations is called broadcast syndication, and today nearly every television station in the United States obtains syndicated programs in addition to network-produced fare.

The Fox Broadcasting Company network, part of Rupert Murdoch's News Corporation, was launched on October 9, 1986. In the 2006–2007 television season, The CW Television Network was launched by the merger of The WB Television Network and the UPN network.

Late in the 20th century, cross-country microwave radio relays were replaced by fixed-service satellites. Some terrestrial radio relays remained in service for regional connections.

Regulation

Federal Communications Commission (FCC) regulations in the United States restricted the number of television stations that could be owned by any one network, company or individual (Concentration of media ownership). This led to a system where most local television stations were independently owned, but received programming from the network through a franchising contract, except in a few big cities that had network owned-and-operated stations (O&O) and independent stations. In the early days of television, when there were often only one or two stations broadcasting in an area, the stations were usually affiliated with several networks and were able to choose which television programs to air. Eventually, as more stations were licensed, it became common for each station to be affiliated with only one network and carry all of the "prime-time" network programs. Local stations occasionally break from regularly scheduled network broadcast programming however, especially when there is local breaking news (e.g. severe weather). Moreover, when stations return to network programming from commercial breaks, the station identification is displayed in the first few seconds before switching to the network's logo.

Another FCC regulation, the Prime Time Access Rule, restricted the number of hours of network programming that could be broadcast on the local affiliate stations. This was done to encourage the development of local programming, and to give local residents access to broadcast time. More often, the result included a substantial amount of syndicated programming, usually consisting of old movies, independently produced and syndicated shows, and reruns of network programs. Occasionally, these shows were presented by a local host, especially in programs that showed cartoons and short comedies intended for children. See list of local children's television series (United States).

Canada

Main articles: Television system and Television in Canada

A number of different definitions of "network" are used by government agencies, industry, and the general public.

Under the Broadcasting Act, a network is defined as "any operation where control over all or any part of the programs or program schedules of one or more broadcasting undertakings is delegated to another undertaking or person"^[9] and must be licensed by the Canadian Radio-television and Telecommunications Commission (CRTC).

Only four national over-the-air television networks are currently licensed by the CRTC: the government-owned CBC (English) and Radio-Canada (French), French-language private network TVA, and a network focused on Canada's indigenous peoples, APTN. A third French-language service, V, is licensed as a provincial network within Quebec, but not nationally.

Currently, licensed national or provincial networks must be carried by all cable systems (in the country or province, respectively) with a service area above a certain population threshold, as well as all satellite providers. However, they are no longer necessarily expected to achieve over-the-air coverage in all areas (APTN, for example, only has terrestrial coverage in parts of northern Canada).

In addition to these licensed networks, the two main private English-language over-the-air services, CTV and Global, are also generally considered to be "networks" by virtue of their national coverage, although they are not officially licensed as such. CTV was previously a licensed network, but relinquished this licence in 2001 after acquiring most of its affiliates, making operating a network licence essentially redundant (per the above definition).

Smaller groups of stations with common branding are often categorized by industry watchers as television systems, although the public and the broadcasters themselves will often refer to them as "networks" regardless. Some of these systems, such as CTV Two, Citytv, and the now-defunct E!, essentially operate as mini-networks, but have reduced geographical coverage. Others, such as Omni or CTS, have similar branding and a common programming focus, but schedules may vary significantly from one station to the next.

Most local television stations in Canada are now owned and operated directly by their network, with only a very few affiliates still operating.

Europe, Asia, Africa and South America

Most television services outside North America are national networks established by a combination of publicly funded broadcasters and commercial broadcasters.^{[citation needed]} Most nations established television networks in a similar way: the first television service in each country was operated by a public broadcaster, often funded by a TV licensing fee, and most of them later established a second or even third station providing a greater variety of content. Commercial television services also became available when private companies applied for television broadcasting licenses. Often, each new network would be identified with their channel number, so that individual stations would often be numbered One, Two, Three, and so forth.

United Kingdom

The first television network in the United Kingdom was provided by the BBC, but commercial broadcasting was established in order to create a second television network. Rather than creating a single network with local stations owned and operated by a single company (as is the case with the BBC), each local area had a separate television station independently owned and operated, although most of these stations shared a number of programmes. Gradually, each of these stations formed the ITV Network.

When UHF television allowed a greater number of television stations to broadcast, the BBC launched a second network, BBC Two (and the original service was later renamed BBC One). A fourth nationwide commercial network was launched, Channel 4, although Wales introduced a Welsh-language service instead, S4C. A fifth network, currently called Channel 5, was later launched. Since the introduction of digital television, the BBC, ITV, Channel 4 and Channel 5 each introduced a number of digital-only channels. The large amount of remaining channels are operated by satellite and virgin media cable only BSkyB and free to view UKTV who operate a number of channels including Dave, GOLD, Watch, yesterday and other more specific channels

Netherlands

Until 1989, Netherlands Public Broadcasting was the only television network in the Netherlands, with three stations, Nederland 1, Nederland 2 and Nederland 3. Rather than having a single production arm, there are a number of public broadcasting organizations that create programming for each of the three stations, each working relatively independently. Commercial broadcasting in the Netherlands is currently operated by two networks, RTL Nederland and SBS Broadcasting, which together broadcast seven commercial stations.

Russia

Soviet era

The first television network of Soviet Union appeared on 4 November 1967 when the Channel One of USSR Central Television became all-union one. Until 1989 there were six TV channels, all owned by the USSR Gosteleradio. This changed during Gorbachev's Perestroika when the first independent television network, 2×2, was launched.

1990s

Following a breakup of the Soviet Union, USSR Gosteleradio ceased to exist as well as its six channels. Only Channel One had a smooth transition to the Ostankino Channel One and the network itself survived. The other 5 networks were Ground Zero. This free airwave space allowed many private television networks like NTV and TV-6 to appear in the mid-1990s.

2000s

2000s were marked by the increased state intervention in Russian Television. On 14 April 2001 NTV television channel had its management changed following the expulsion of former oligarch and the founder of NTV Vladimir Gusinsky. As a result most of the star reporters left the channel. Later, on 22 January 2002, the second biggest private television network TV-6, where the former NTV staff took refuge, was shut down allegedly because of its editorial policy. Five months later, on 1 June TVS was launched, mostly consisting of NTV/TV-6 staff, only to stop airing 1 year later. Since then four biggest TV networks (Channel one, Russia 1, NTV and Russia 2) are state-owned.

Still, 2000s saw a rise of several independent TV networks like REN (its coverage increased vastly allowing it to become federal channel), Petersburg — Channel Five (overall the same), the relaunched 2×2 and others. Now the TV audience is mainly shared by 5 leading companies: Channel one, Russia 1, NTV, TNT and CTC.

Australia

See also: Television in Australia

Australia has two national public networks, the ABC and SBS. The ABC operates eight stations as part of its main network ABC1, one for each state and territory, as well as three digital-only channels, ABC2, ABC3 and ABC News 24. SBS currently operates two stations, SBS One and SBS Two.

The first commercial networks in Australia involved commercial stations in Sydney, Melbourne, Brisbane, Adelaide, and later Perth, sharing programming, with each network forming networks based on their allocated channel numbers: TCN-9 Sydney, GTV-9 Melbourne, QTQ-9 Brisbane, NWS-9 Adelaide and STW-9 Perth together formed the Nine Network, while their equivalents on VHF channels 7 and 10 formed the Seven Network and Network Ten respectively. Until 1989, areas outside of these main cities had access to only a single commercial station, and these rural stations often formed small networks such as Prime Television. Beginning in 1989, however, television markets in rural areas began to aggregate, allowing these rural networks to broadcast over a larger area, often an entire state, and become full-time affiliates to one specific metropolitan network.

Philippines

In the Philippines, in practice, the terms network, station and channel are used interchangeably as programming line-ups are mostly centrally planned from the networks' main offices, and since provincial/regional stations usually just relay the broadcast from their parent company network's flagship station (usually based in the Mega Manila area). Hence VHF networks are sometimes informally referred to by the channel number they are seen on terrestrial TV in the Mega Manila area (e.g. Channel 2 or Dos for ABS-CBN, Channel 5 or Singko for TV5, and Channel 7 or Siyete for GMA Network) while some networks have the channel numbers in their name (e.g. TV5, Studio 23 and Net 25 which are seen on channels 23 and 25 respectively).

Unlike the US where networks get programmes from various production houses, the two largest networks in the Philippines produce all their prime time programmes except for Asianovelas. Other networks adopt block-time programming whose programming arrangements are similar to the relationship between a US network and station. And also Philippines has network wars in which the fans of the 2 major networks defend their favorite channel, or when the 2 major networks produce similar and rival programming, and example of this, is when an ABS-CBN fan tells an insult on GMA (usually being called cheap), and a GMA fan would answer and make another insult (usually the answer is that ABS-CBN is mayabang (arrogant in English), and an exchange of insults would occur, usually on social networking sites, especially Facebook. In terms of programming, for example, after the launch of Showtime, GMA launched Diz Iz It!, but was cancelled due to the former's popularity, and the latter was called a copycat and cheap. But the real definition of the network wars is that the 3 networks battle for ratings supremacy.
