DD National (DD1) is a state-owned general interest terrestrial television channel in India. It is the flagship channel of Doordarshan, the Indian public service broadcasting corporation, and the most widely available terrestrial television channel in India.

DD National is a government body but it has its own editorial independence.

On 15 September 1959, at the studio of All India Radio, Delhi, the very first TV channel in India, started an experimental telecast with a small transmitter and a makeshift studio. Until 1965, DD was part of All India Radio, so all the regular daily transmissions were operated by All India Radio. On 15 August 1982, Doordarshan introduced a national telecast service from its own TV studio in Mandi House, New Delhi. This telecast was named DD1 Channel and started regular transmission. Krishi Darshan, Chaupaal, Samachar, and Kalyani were the first programs on the channel.

In 1984, DD1 Channel started telecast of sponsored TV serials, which were produced by veteran filmmakers. Hum Log was the first TV serial of Indian television, and started airing on 7 July 1984. After the success of Hum Log, many other TV producers and filmmakers created many popular shows.
