Each company would be (and nominally still is) afforded a 'franchise' to broadcast to a specific coverage area of the UK, with larger areas sometimes having two broadcasters 'time-sharing' a channel between weekdays and weekends. A separate nationwide 'breakfast' franchise also began in 1983. Most viewers would only receive one service (unless they happened to receive signals from two transmitters in different areas). Each regional 'franchisee' would broadcast a combination of unique regional programmes and shared 'networked' content aired nationwide; the latter practice becoming ever more commonplace throughout the network's history. Originally each company would broadcast with their own, unique station name, such as "

For many years, the ITA, IBA and the ITV companies campaigned for further frequencies on which to broadcast, though these goals were never wholly realised on analogue.


Channel 4 and S4C

After many decades of demand by the commercial broadcasters for a second commercial station or network of stations,

and S4C were launched in 1982. Channel 4 was originally run as a uniform national service, by the IBA through a subsidiary, the Channel Four Broadcasting Company. Channel 4 does not make the programmes it broadcasts; content is commissioned from independent, private production companies such as the ITV companies and companies not related to ITV who had previously little space to broadcast in the UK. Channel 4 was originally funded by allowing each local ITV franchisee to sell adverts during the station's airtime in their area in exchange for a guaranteed income to be paid to the IBA. The station was established with the intention to provide programmes for minority groups and cater for specialist interests and has a remit that details these obligations. Since the abolition of the IBA, which took effect in 1993, Channel 4 has been run by the publicly owned,

and manages its own advertising. S4C ( cy, Sianel Pedwar Cymru; ''Channel 4 Wales'') began broadcasts the day before Channel 4 after demands for a dedicated Welsh-language service for Wales. Previously ITV and the BBC were obliged to air Welsh language programmes, though these were often shown at off-peak times. S4C broadcast in place of Channel 4 which would never be available in Wales via analogue terrestrial; consequently some Channel 4 programmes were aired during off-peak times on S4C. Digital platforms in Wales provide both services; S4C's digital variant airing Welsh-language content only. S4C is operated by the S4C Authority, independent of the IBA and latterly Ofcom and is funded through advertising and direct government funding. The BBC also airs its Welsh language programmes on the service, funded by the licence fee. S4C ceased broadcasting on analogue at the end of March 2010, when the last analogue television transmissions in Wales ended.


Channel 5

A fifth service was licensed during the 1990s and began broadcasts in 1997, called Channel 5, it has since been re-branded as Five and later back to Channel 5 in August 2010. The Channel 5 licence has one single licensee and provides a nationwide service. Compared to the other analogue broadcasters, it has relatively few public-service obligations, provision of news programming being one exception. Limited space within the analogue television bands meant Channel 5 had substantially reduced coverage compared to the other networks, at around 70% coverage.


Restricted service licences

In addition to the five national networks, a limited number of local stations were broadcast to various towns and cities under what was known as a
Restricted Service Licence A UK Restricted Service Licence (often called an RSL), is typically granted to radio stations and television stations broadcasting within the UK to serve a local community or a special event. Licences are granted by the broadcasting authority Ofc ...

625 line system

1964 saw the launch of a third television service, known as BBC2, and with it the introduction of the 625 line service on UHF Bands IV and V. Whilst the extra lines theoretically offered better resolution and picture clarity, the fledgling network of new transmitters required to provide the service offered far inferior coverage compared with the existing VHF services and was prone to increased interference often resulting in poor picture quality. Furthermore, few people had the new sets required to receive the new service or the different type of aerial required to pick up the UHF signal.


Colour

During the late 1950s, when the decision to introduce colour television was first seriously mooted, the then two main systems for consideration were the French

Broadcast on this system officially commenced in 1967 with BBC2's (and the UK's) launch of colour television programming, though previous years had seen many unofficial colour test films outside of official broadcasting hours, including some which trialled NTSC and SECAM. BBC2 was joined in 1969 by

digital audio system used since the early 1970s for transmitting the audio carrier signal of a broadcast between two or more regional broadcasters and sometimes to the transmitters, where it was converted back to an analogue FM audio carrier 6 MHz above the video carrier signal. Reception of the NICAM signal provided the user had a VCR or a TV capable of decoding the NICAM signal, which was broadcast on a carrier 6.552 MHz above the video carrier, and thus just 0.552 MHz above the FM mono audio carrier. The first UK NICAM stereo broadcast was made in May 1986 on BBC2, NICAM slowly being rolled out across the UK and across the broadcaster's programme schedules over the next 5 years, culminating in the official launch of NICAM on the BBC in 1991, ITV and Channel 4 having begun broadcasting NICAM in 1989 and 1990 respectively. The service was sometimes referred to by its full, official, name, NICAM-728 – the 728 denoting the datarate of the digital stereo information – the datarate was 728kbit/s, non- PCM.


Channel allocations

The 625 line system divided the spectrum into 44 channels, 21–34 and 39–68 (Bands IV and V). These channels were allocated, by the GPO, to the broadcasters to allow for four networks to operate with eventual maximum coverage and minimum cross-network interference. The two BBC channels and the ITV network were catered for, as well as space for a future fourth network, at the time expected to be a second network for the ITA. The fourth network didn't come into being until the

s, requiring a massive equipment retuning exercise to be undertaken at the broadcaster's expense. Additionally, lack of compatibility with older antennas, plus existing use of the channels by stations in France, meant that Channel 5 never acquired the level of analogue coverage enjoyed by the other broadcasters.


Digital switch-over

The government was committed to switching terrestrial television broadcasting to fully digital by 2012. The digital network features six multiplexes at each of the 80 main nodes, at other nodes there is only three multiplexes because fewer broadcasters were interested in the less densely populated regions. A company called

It was also announced that a support scheme would be put in place to ensure that no one is left behind in the switch. It provided help with equipment and installation and follow-up support for people aged 75 years and over and people with significant disabilities. The scheme was funded by the BBC through the licence fee. The final region to switch off was
