The motto of Doordarshan is "Satyam Shivam Sundaram" which translates as : 'The Truth is The God and The God is Beautiful'.

The Television service in India was started by All India Radio in 1 November 1959 on experimental basis in its Research Department with a small transmitter and a make-shift studio. The regular daily transmission began in 1965. The service was extended to Bombay in 1972. By 1975, the TV services were available in 7 cities.
Television was separated from Radio on 1 April 1976. The name of new organisation was given as 'Doordarshan'. National Programme was introduced in 1982. At the time of 1982 Asian Games in Delhi, the black-&-white transmission was converted to the colour. In July 1984, Doordarshan started its ambitious scheme for the expansion of its coverage in the country by installing one-transmitter-a-day.
Doordarshan is headed by a Director General (DG), who is an ex-officio member of Prasar Bharati Board. Engineering activities in Doordarshan are supervised by Engineer-in-Chief (E-in-C), assisted by Additional Director Generals (ADGs).
Doordarshan is one of the largest broadcasting organisations in the world in terms of the infrastructure of studios and transmitters, the variety of software and the vastness of the viewer-ship.
