Television and radio broadcasting in unencrypted form

Free to air (FTA) services are television (TV) and radio services broadcast in unencrypted form, allowing any person with the appropriate receiving equipment to receive the signal and view or listen to the content without requiring a subscription, other ongoing cost, or one off fee (e. g., pay per view). In the traditional sense, this is carried on terrestrial radio signals and received with an antenna. FTA also refers to channels and broadcasters providing content for which no subscription is expected, even though they may be delivered to the viewer/listener by another carrier for which a subscription is required, e. g., cable television, the Internet, or satellite. These carriers may be mandated (or OPT) in some geographies to deliver FTA channels even if a premium subscription is not present (providing the necessary equipment is still available), especially where FTA channels are expected to be used for emergency broadcasts, similar to the 1 1 2 (112) emergency service provided by mobile phone operators and manufacturers. On the other side, free to view (FTV) is generally available without subscription, but it is digitally encoded and may be restricted geographically. Free to air is often used for international broadcasting, making it something of a video equivalent to shortwave radio. Most FTA retailers list free to air channel guides and content available in North America for free to air use.

In 1971, the SABC was finally allowed to introduce a television service. Initially, the proposal was for two television channels, one in English and Afrikaans, aimed at white audiences, and another, known as TV Bantu, aimed at black viewers. However, when television was finally introduced, there was only one channel with airtime divided evenly between English and Afrikaans, alternating between the two languages. Test transmissions in Johannesburg began on 5 May 1975, followed in July by ones in Cape Town and Durban. Nationwide services finally commenced on 5 January 1976. In common with most of Western Europe, South Africa used the PAL system for colour television, being only the second terrestrial television service in sub Saharan Africa to launch with a colour only service, Zanzibar in Tanzania having introduced the first such service in 1973. (Tanzania itself did not establish a television service until the early 1990s, similarly concerned about the expense and perceived threat to cultural norms.) The Government, advised by SABC technicians, took the view that colour television would have to be available so as to avoid a costly migration from black and white broadcasting technology. Initially, the TV service was funded entirely through a licence fee as in the UK, charged at R36. However, advertising began on 1 January 1978. On 1 January 1982, two services were introduced, TV2 broadcasting in Zulu and Xhosa and TV3 broadcasting in Sotho and Tswana, aimed at a black urban audience. In 1985, a new service called TV4 was introduced, carrying sports and entertainment programming, using the channel shared by TV2 and TV3, which ended transmissions at 9:30 pm. In 1992, TV2, TV3 and TV4 were combined into a new service called CCV (Contemporary Community Values). A third channel was introduced known as TSS, or Topsport Surplus, Topsport being the brand name for the SABC's sport coverage, but this was replaced by NNTV (National Network TV), an educational, non commercial channel, in 1994. The main channel, now called TV1, was divided evenly between English and Afrikaans, as before. It also became available in Walvis Bay, an enclave of South Africa in Namibia, which was itself then under South African administration, with a live feed of the channel broadcast via Intelsat being retransmitted on a local low power repeater. In 1986, the SABC's monopoly was challenged by the launch of a subscription based service known as M Net, backed by a consortium of newspaper publishers on 1 October. However, as part of its licensing restrictions, it could not broadcast news programmes, which were still the preserve of the SABC, although M Net started broadcasting a current affairs programme called Carte Blanche in 1988. As the state controlled broadcaster, the SABC was accused of bias towards the apartheid regime, giving only limited coverage to opposition politicians.

In Hong Kong, the largest and most dominant television channel, Television Broadcasts Limited, was the first free to air commercial television channel when it commenced broadcasting on 19 November 1967. It may also well be among the oldest and first station to broadcast over the air in East and Southeast Asia. ViuTV and RTHK TV started broadcasting in 2016.

Around 600 FTA television channels and 180 Radio Channel are broadcast from ku band and c band transponders on the INSAT 4B and GSAT 15 satellite covering India, Pakistan, Bangladesh, Bhutan, Nepal, Sri Lanka and parts of Afghanistan, and Myanmar. In India, the channels are marketed as DD Direct Plus/ DD Free Dish by Doordarshan, India's national broadcaster and other Indian private broadcaster ABS Free Dish from the ABS2 satellite, one can receive free to air regional TV channels using small DTH antenna and freetoair set top box.

In Korea, KBS, MBC (the 2 main public broadcasters), SBS (privately owned, but available for free to viewers), and EBS (including both TV and radio) are the free to air broadcasting stations. They dominate more than 80% of advertisement profits, according to the recent survey from the agency Due to the recent government's decision, digital television service for all free to air networks would be scheduled before the year 2012, followed by the end of analog television broadcasting.

European countries have a tradition of most television services being free to air. Germany, in particular, receives in excess of 100 digital satellite TV channels free to air. Approximately half of the television channels on SES Astra's 19.2° east and 28.2° east satellite positions, and Eutelsat's Hot Bird (13° east) are free to air. A number of European channels which one might expect to be broadcast free to air including many countries' national terrestrial broadcasters do not do so via satellite for copyright reasons. (Rights to purchase programs for free to air broadcast, especially via satellite, are often higher in price than for encrypted broadcast.) The lack of FTA among public broadcasters are prevalent in countries whose broadcasters tend to use subtitles for foreign language programmes; although Spain's two public domestic channels, La Una and La Dos, are also encrypted despite dubbed foreign programmes being the norm in Spain. However, these channels usually provide a scheme to offer free, but encrypted, viewing with free to view broadcasts. Certain programming on Italy's RAI, and the majority of Dutch channels are covered by such schemes (although in the case of RAI some programming is transmitted without encryption where there are no copyright issues). In Austria, the main national networks broadcast free to view via satellite; however, all regional and some smaller channels are transmitted free to air, and the national public broadcaster, ORF, offers a special free to air channel which airs selected programming without (i. e. those without copyright issues) via satellite all over Europe. As Germany and Austria speak the same language and use the same satellite, Austrian viewers are able to receive about 120 free German speaking channels from both countries. In general, all satellite radio in Europe is free to air, but the more conventional broadcast systems in use mean that SiriusXM style in car reception is not possible. Cable and satellite distribution allow many more channels to carry sports, movies and specialist channels which are not broadcast as FTA. The viewing figures for these channels are generally much lower than the FTA channels.

Various European countries broadcast a large number of channels via free to air terrestrial, generally as an analog PAL/SECAM transmission, digital DVB T/T2 or a combination of the two.

In Croatia eleven national channels are free to air: HRT 1, HRT 2, HRT 3, HRT 4 (HRT being national broadcaster), Nova TV, Doma TV, RTL, RTL2, RTL Kockica, CMC and SPTV. There are around 21 local or regional channels. Before June 2020, they used to be transmitted via three OiV (state owned public broadcasting company) DVB T and one DVB T2 (HEVC/H.265) MUXes. As of June 2020, the DVB T MUXes were switched off and all eleven national channels are now distributed via two OiV DVB T2 (HEVC/H.265) MUXes.

In Denmark, six channels are as of 2020 free to air, distributed via 18 main transmitter sites and 30 smaller, auxiliary transmitters. The six channels (DR1, DR2, DR Ramasjang, Folketinget, TV2 Regionerne, and sign language/local programme) come in one DVB T2 multiplex.

In the Netherlands, 3 national public television channels NPO 1, NPO 2 and NPO 3, and 7 national public radio channels broadcast free to air via the DVB T Digitenne service. The television and radio channels of the regional public broadcasters are also free to air via the DVB T service.

In the UK, the five main free to air television networks are BBC One, BBC Two, ITV, Channel 4 and Channel 5. Around 108 free to air television channels and 30 free to air radio channels are available terrestrially via the Freeview DVB T service. Seven HD channels are also broadcast via a public service broadcast multiplex and a commercial multiplex, both DVB T2. The informal term "council telly" is sometimes used for free to air television in the UK, evoking a basic service accessible to all.

Australia has five major free to air networks: the two public broadcasting networks ABC and SBS, and three commercial networks Seven Network, Nine Network, and Network 10. Traditionally each network had only a single channel in a geographic area, but with the advent of digital television each network started broadcasting several SD multichannels, such as 7two, 9Gem, 10 Bold, and SBS Food, as well as at least one HD channel. There are also free to air community television channels in some major cities. Viewers in remote parts of Australia are able to access many Australian free to air channels using the DVB S2 Optus VAST service.

New Zealand has a number of FTA broadcasters such as Television New Zealand's TVNZ 1 and TVNZ 2, as well as Discovery New Zealand's Three and Bravo, Sky Network Television's Sky Open and the government subsidised the Whakaata Māori and Te Reo channels.

Local stations such as CTV and Face TV (previously Triangle TV) were free to air analogue PAL transmissions prior to CTV migrating to the free to air digital DVB T service and Face TV's terrestrial free to air service shutoff from December 2013. A digital terrestrial version of Freeview was launched in 2008, which, unlike the analogue and free to air satellite options, supports high definition broadcasts for TVNZ 1, TVNZ 2, Three and Bravo.
