All India Radio (AIR)
Sound broadcasting started in India in 1927 with the proliferation of private radio clubs. The operations of All India Radio began formally in 1936, as a government organisation, with clear objectives to inform, educate and entertain the masses.
All India Radio was created in 1936.
AIR stands for "All India Radio," which is a public service broadcaster in India.
In British India, broadcasting began in June 1923 with programmes by the Radio Club of Bombay and other radio clubs. According to an agreement of 1926, the private Indian Broadcasting Company (IBC) was authorized to operate two radio stations; the Bombay station began on 23 July 1927, and the Calcutta station followed on 26 August 1927. On 1 March 1930, however, the company went into liquidation. The government took over the broadcasting facilities, beginning the Indian State Broadcasting Service (ISBS) on 1 April 1930 (on an experimental basis for two years, and permanently in May 1932). On 8 June 1936 the ISBS was renamed All India Radio. On 1 October 1939 the External Service began with a broadcast in Pushtu; it was intended to counter radio propaganda from Germany directed to Afghanistan, Iran and the Arab nations. When India became independent in 1947 the AIR network had only six stations (in Delhi, Bombay, Calcutta, Madras, Lucknow, and Tiruchi); the total number of radio sets at that time was about 275,000. On 3 October 1957 the Vividh Bharati Service was launched, to compete with Radio Ceylon. Television broadcasting began in Delhi in 1959 as part of AIR, but was split off from the radio network as Doordarshan on 1 April 1976.[2] FM broadcasting began on 23 July 1977 in Madras, and was expanded during the 1990s.[3]
