Doordarshan is the public television broadcaster of India and a division of Prasar Bharati, a public service broadcaster nominated by the Government of India. It is one of the largest broadcasting organizations in the world in terms of the infrastructure of studios and transmitters. Recently, it has also started Digital Terrestrial Transmitters. On September 15 2009, Doordarshan celebrated its 50th anniversary.
Doordarshan had a modest beginning with the experimental telecast starting in Delhi on 15 September 1959 with a small transmitter and a makeshift studio. The regular daily transmission started in 1965 as a part of All India Radio. The television service was extended to Bombay and Amritsar in 1972. Till 1975, seven Indian cities had television service and Doordarshan remained the only television channel in India. Television services were separated from radio in 1976. Each office of All India Radio and Doordarshan were placed under the management of two separate Director Generals in New Delhi. Finally Doordarshan as a National Broadcaster came into existence.
National telecasts were introduced in 1982. In the same year, colour TV was introduced in the Indian market with the live telecast of the Independence Day speech by then prime minister Indira Gandhi on 15 August 1982, followed by the 1982 Asian Games being held in Delhi. Now more than 90 percent of the Indian population can receive Doordarshan (DD National) programmes through a network of nearly 1400 terrestrial transmitters and about 46 Doordarshan studios produce TV programs today.
Presently, Doordarshan operates 19 channels – two All India channels-DD National and DD News, 11 Regional languages Satellite Channels (RLSC), four State Networks (SN), an International channel, a Sports Channel and two channels (DD-RS & DD-LS) for live broadcast of parliamentary proceedings.
On DD National(DD-1), Regional programmes and Local Programmes are carried on time-sharing basis. DD-News channel, launched on 3 November 2003, which replaced the DD-Metro Entertainment channel, provides 24-Hour news service. The Regional Languages Satellite channels have two components – The Regional service for the particular state relayed by all terrestrial transmitters in the state and additional programmes in the Regional Language in prime time and non-prime time available only through cable operators. DD-Sports Channel is exclusively devoted to the broadcasting of sporting events of national and international importance. This is the only Sports Channels which telecasts rural sports like Kho-Kho, Kabbadi etc. something which private broadcasters will not attempt to telecast as it will not attract any revenues.
DD-India is being broadcasted internationally through Satellite. It is available in 146 countries worldwide, however the information on picking up this channel in other countries is not easily available. In the UK, DD-India was available through the Eurobird Satellite on the Sky system on Channel 833 (the logo is shown as Rayat TV). The timing and programming of DD-India international is different from that of India. Transmissions for Sky Digital U.K. stopped in June 2008 and DirecTV U.S. stopped in July 2008.
