BBC Home Service
Between the 1920s and the outbreak of the Second World War, the BBC had developed two nationwide radio services, the BBC National Programme and the BBC Regional Programme. As the name of the latter suggests, as well as a "basic" service programmed from London, the Regional Programme included a large measure of additional, alternative or rescheduled programming originating in six regions. Although the programmes attracting the greatest number of listeners tended to appear on the National, the two services were not streamed – that is, they did not attempt to appeal to different audiences; instead, they appealed to a single audience but provided a choice of programming.
World War II 
On 1 September 1939, the BBC merged the National and the Regional Programmes into one national service from London. The reasons given for this included the need to prevent enemy aircraft from using differentiated output from the Regional Programme's transmitters as navigational beacons. To this end, the former "regional" transmitters were synchronised in chains on (initially) two frequencies, 668 and 767 kHz, with an additional chain of low powered transmitters (known as "Group H") on 1474 kHz appearing later. Under this arrangement "regional" broadcasting in its pre-war form was no longer feasible; however, much of the programming on the new service was gradually decentralised to the former "regional" studios (because of the risks from enemy attack/bombing/invasion in London) and broadcast nationally.
The new service was named the Home Service, which was also the internal designation at the BBC for domestic radio broadcasting (the organisation had also had Television Service and Overseas Service departments).
On 29 July 1945, the BBC resumed its previous regional structure and began "streaming" its radio services. Following the wartime success of the Forces and General Forces Programmes, light entertainment was transferred to the new BBC Light Programme, whilst 'heavier' programming – news, drama and talks – remained on the now-regionalised Home Service.
However, popular light programming from the former national Home Service – such as ITMA – remained on the new Home Service; similarly, some speech programming of the type pioneered by the Forces Programmes – the newly-launched Woman's Hour being very much in this mould – remained on the new Light Programme.
The Home Service had seven regions.
A shortage of frequencies meant that the Northern Ireland Regional Home Service was treated as part of the North Regional Home Service, as the Northern Ireland service used the same frequency as a North service booster. The Northern Ireland service was separated from the North region on 7 January 1963.
|Regional Home Service||Home city||Wavelength (metres)||Frequency (kHz)|
|Basic||London||330 (plus a local booster on 202)||908 (1484)|
|North||Manchester||434 (plus local boosters on 261 and 202)||692 (1151, 1484)|
|West||Bristol||285 and 206||1052 and 1457|
|Northern Ireland||Belfast||261 until 1963; 224 thereafter.||1151, 1340|
As well as five national news programmes a day from London, the Home Service also provided drama, talks and informational programmes. After the BBC Third Programme began broadcasting on 29 September 1946, non-topical talk programmes and heavier drama output were transferred to the new network.
During the day, the Home Service included in its schedules a number of programmes of "serious" (classical) music. These were reduced in number when government limits on radio broadcasting hours were relaxed in 1964 and the BBC Music Programme began broadcasting during the daytime on the frequencies of the (evening-only) Third Programme. They disappeared entirely when the Music Programme began regular 0700–1830 daily broadcasting on 22 March 1965.
The Home Service broadcast educational programmes for use in schools during the day, backed with booklets and support material available from the BBC.
Programmes were reorganised across the three BBC networks on 30 September 1957, with much of the Home Service's lighter content transferring to the Light Programme and the establishment of the BBC Third Network, which used the frequencies of the Third Programme to carry the Home Service's adult education content (BBC Study Session) and the Home and Light's sports coverage (BBC Sports Service) as well as the Third Programme itself.
Becomes BBC Radio 4 
On 30 September 1967, the BBC split the Light Programme into two services: a popular music service and an entertainment network. The Corporation took the opportunity of renaming the national networks from the same date. The Light Programme became BBC Radio 1 and BBC Radio 2. The Third Network became BBC Radio 3, with the Music Programme losing its separate identity (the Third Programme, Study Session, and Sports Service, however, retained their identities – under the banner of BBC Network Three – until 4 April 1970).
The BBC Home Service was renamed BBC Radio 4.
Regional radio legacy 
BBC Radio 4 continued as a regionalised service and continued to use the term "Home Service" to refer to regional programming and scheduling, with the Radio Times listings being headlined "BBC Radio Four - Home Service".
"Broadcasting in the Seventies" 
With the introduction of BBC Local Radio, starting with BBC Radio Leicester on 8 November 1967, it was felt that the future of non-national broadcasting lay in local rather than regional services. To this end, the BBC produced a report, Broadcasting in the Seventies, on 10 July 1969, proposing the reorganisation of programmes on the national networks and the end of regional broadcasting.
The report began to be implemented on 4 April 1970 and the Home Service regions gradually disappeared (with some of its frequencies reallocated to Independent Local Radio), until 23 November 1978 when Radio 4 was given the national longwave frequency previously used by Radio 2 and was relaunched as Radio 4 UK (with two additional longwave transmitters opened in Scotland).
National regions 
The "national regions" survived to become separate stations – BBC Radio Scotland, BBC Radio Wales / BBC Radio Cymru and BBC Radio Ulster – at first relaying the majority of Radio 4 programming but later becoming completely independent.
South West region 
The last remaining Regional Home Service was an FM opt-out of Radio 4 for Devon and Cornwall. This "South West Region", also carried on several low power medium-wave transmitters, continued in existence until BBC Radio Cornwall and BBC Radio Devon opened on 17 January 1983.
East Anglia region 
During the 1970s Radio 4 FM in the East of England (Tacolneston, Peterborough and relays) carried a breakfast magazine programme, Roundabout East Anglia, the region lacking any BBC Local Radio stations. The service closed in advance of the opening of BBC Radio Norfolk in 1980.
English regional news bulletins 
Radio 4 FM continued to carry four daily five-minute regional news bulletins on Mondays to Saturdays until the early 1980s, by which time BBC Local Radio had reached most areas of England. The wide coverage of the Holme Moss transmitter meant that listeners in much of Northern England received combined North and North-West news.
