It is also important to note that some countries have launched national television networks, so that individual television stations can act as common repeaters of nationwide programs. On the other hand, television networks also undergo the impending experience of major changes related to cultural varieties. The emergence of cable television has made available in major media markets, programs such as those aimed at American bi-cultural Latinos. Such a diverse captive audience presents an occasion for the networks and affiliates to advertise the best programming that needs to be aired. This is explained by author Tim P. Vos in his abstract ''A Cultural Explanation of Early Broadcast'', where he determines targeted group/non-targeted group representations as well as the cultural specificity employed in the television network entity. Vos notes that policymakers did not expressly intend to create a broadcast order dominated by commercial networks. In fact, legislative attempts were made to limit the network's preferred position.

s beginning with the letter "W"; those west of the Mississippi were assigned calls beginning with a "K". The number of programs that 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 their own programs and expanding the total coverage beyond the limits of a single broadcast signal, was devised.

, soon followed suit, each network signed hundreds of individual stations on as affiliates: stations which agreed to broadcast programs from one of the networks. As radio prospered throughout the 1920s and 1930s, experimental television stations, which broadcast both an audio and a video signal, began sporadic broadcasts. Licenses for these experimental stations 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, required a broadband transmission medium. Transmission by a nationwide series of radio relay towers would be possible but extremely expensive. Researchers at

Regulation

FCC regulations in the United States restricted the number of television stations that could be owned by any one network, company or individual. 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 major cities that had owned-and-operated stations (O&O) of a network and independent stations. In the early days of television, when there were often only one or two stations broadcasting in a given market, the stations were usually affiliated with multiple networks and were able to choose which programs would air. Eventually, as more stations were licensed, it became common for each station to be exclusively affiliated with only one network and carry all of the "prime-time" programs that the network offered. Local stations occasionally break from regularly scheduled network programming however, especially when a

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," and must be licensed by the Canadian Radio-television and Telecommunications Commission (CRTC). Only three national over-the-air television networks are currently licensed by the CRTC: government-owned CBC Television (English) and Ici Radio-Canada Télé (French), French-language private network

, but is not licensed or locally distributed (outside of carriage on the digital tiers of pay television providers) on a national basis. Currently, licensed national or provincial networks must be carried by all cable providers (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

, 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 license in 2001 after acquiring most of its affiliates, making operating a network license essentially redundant (per the above definition). Smaller groups of stations with common branding are often categorized by industry watchers as

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. Most nations established television networks in a similar way: the first television service in each country was operated by a

public broadcaster Public broadcasting involves radio, television and other electronic media outlets whose primary mission is public service. Public broadcasters receive funding from diverse sources including license fees, individual contributions, public financing ...

, often funded by a television 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.

). On 2 November 1936 the BBC opened the world's first regular high-definition television service, from a 405 lines transmitter at Alexandra Palace. The BBC remained dominant until eventually on 22 September 1955, commercial broadcasting was established to create a second television network. Rather than creating a single network with local channels owned and operated by a single company (as is the case with the BBC), each local area had a separate television channel that was independently owned and operated, although most of these channels shared a number of programmes, particularly during peak evening viewing hours. These channels formed the

launched on 22 March 1951 when Channel One of USSR Central Television became a unionwide network. Until 1989, there were six television networks, all owned by the USSR Gosteleradio. This changed during Mikhail Gorbachev's Perestroika program, when the first independent television network, 2×2, was launched.

1990s

Following the breakup of the Soviet Union, USSR Gosteleradio ceased to exist as well as its six networks. Only Channel One had a smooth transition and survived as a network, becoming Ostankino Channel One. The other five networks were operated by Ground Zero. This free airwave space allowed many private television networks like

. As a result, most of the prominent reporters featured on NTV left the network. Later on 22 January 2002, the second largest 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 employing NTV/TV-6 staff, only to cease operations the following year. Since then, the four largest television networks (Channel One, Russia 1, NTV and Russia 2) have been state-owned. Still, the 2000s saw a rise of several independent television networks such as REN (its coverage increased vastly allowing it to become a federal network), Petersburg – Channel Five (overall the same), the relaunched 2×2. The Russian television market is mainly shared today by five major companies: Channel One, Russia 1, NTV, TNT and CTC.

In the 1960s, the service operated at the time by the New Zealand Broadcasting Corporation was four separate television stations – AKTV2 in Auckland, WNTV1 in Wellington, CHTV3 in Christchurch and DNTV2 in Dunedin – which each ran their own newscast and produced some in-house programmes, with other shows being shared between the stations. Programmes and news footage were distributed via mail, with a programme airing in one region being mailed to another region for broadcast the following week. A network was finally established in 1969, with the same programmes being relayed to all regions simultaneously. From the 1970s to the 1990s, locally produced programmes that aired on TV One and TV2 were produced out of one of the four main studios, with TVNZ's network hub based in Wellington. Today, most locally produced programmes that are aired by both TVNZ and other networks are not actually produced in-house, instead they are often produced by a third party company (for example, the TV2 programme ''Shortland Street'' is produced by
