DOORDARSHAN

Doordarshan (Hindi: द   रूदशन ; literally Far Vision) is the public television broadcaster of India and

a division of Prasar Bharti, 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.

Beginning 

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 (now

Mumbai) and Amritsar in 1972. Up until 1975, only seven Indian cities had a television service and

Doordarshan remained the sole provider of television 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, in 1982, Doordarshan as a

National Broadcaster came into existence.

Nationwide transmissionNational 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 primeminister Indira Gandhi on 15 August 1982, followed by the 1982 Asian Games which were

held in Delhi. Now more than 90 percent of the Indian population can receive Doordarshan(DD National) programmed through a network of nearly 1,400 terrestrial transmitters. There

are about 46 Doordarshan studios producing TV programs today.

DOORDARSHAN KENDRA: BHOPAL

(A brief history) 

The studio of Doordarshan Kendra Bhopal was commissioned on 20th October 1992. It started as aRegional Kendra and has ever since played a major role as a Public Service Broadcaster for viewers

of the state. It has enormously enriched the ethos of this land while projecting and promoting the

cultural heritage of the State. With the passage of time, program activities of the Kendra have

witnessed manifold changes through which basic objectives of Doordarshan viz. INFORMATION,EDUCATION, AND ENTERTAINMENT have been provided to the masses. Various program

formats like live phone in program, serials, telefilms, variety show, concerts poetic symposiums,

ELECTRONICS & COMMUNICATION

quiz features, multi segmented magazine programs and programs for specific target audience like

children, youth, women and physically challenged people have been adopted.

The Kendra has produced special program on specific themes like socio cultural heritage,environmental awareness, family welfare, health care, population control, legal awareness,

promotion of tourism, promotion of sports, public grievances and promotion of national integrationand communal harmony.

In order to come up to the ever increasing expectations of the public, many reforms have been

adopted in the overall program pattern through which aspirations of different sections of the society

have been taken care of. The quantum of in-house production has been increased which has raised

opportunities for different scholars, artists and other talented persons to get associated with programs

of their choice through which their talent is ventilated. Introduction of interactive formats with

suitable treatment has added color to our transmission. Quick response and spontaneous feedback 

from the public through live phone in programs has enhanced access of the viewers which has gone

a long way in establishing credibility of the Kendra. Efforts are continuously made to cast our net as

far and wide as possible within the constraints to net in fresh talent. Instead of restricting ourprogram activity to the four walls of studio, the Kendra has tried to take the TV closer to the door

steps of viewers. Various ENG and OB teams have recorded programs on natural locations in

different formats.

Although the main language of transmission is Hindi, yet programs in other dialects which are

spoken in the different parts of MP viz. Bagheli, Bundeli, Nimari & Malvi are also included in our

telecasts.

Optimum utilization of manpower, equipment and other infrastructural facilities has changed the

complete working of the Kendra. On an average 3 to 5 programs are generated inside the studios and

about 6 to 8 programs or News coverage on outdoor locations with ENG facilities per day.
