Television
Introduction
Television was first invented by JL Baird of Scotland in the year 1944. Television is a kind of wireless machine on which we can see distant objects through its radio action. TV machines can be powered by batteries or electricity.
How TV works
Television works with the help of electronics. We buy TV receivers that receive data and sound from a TV hub. The main feature of a TV center is its tower. The figures on TV receivers may be stationary or in action. These figures can be plain or colored.
Television in India
The first regular TV broadcast started in the year 1965 in Delhi. The TV station in Mumbai was established in the year 1972. The TV Tower in Mumbai TV Station is the tallest and self-supporting TV Tower in our country.
It is three hundred meters high. Later, TV stations were established in Amritsar, Srinagar, and Kolkata (Calcutta). Kolkata (Calcutta) became a TV City with effect from 9 August 1975. Indians are now making TV receivers.
In Odisha, a government enterprise in Bhubaneswar is manufacturing TV sets. Last August 1975, TV programs were broadcast through Satellite Instructional Television Experiments (SITE) to two thousand five hundred (2,500) villages in six states of India.
These six states are Andhra Pradesh, Bihar, Karnataka, Madhya Pradesh, Orissa and Rajasthan. These villages were provided 2,000 special TV sets by the United States National Aeronautical and Space Administration (NASA) to receive programs directly from an artificial Earth satellite located over the Indian Ocean.
These special TV sets were designed by the Indian Space Research Organization (ISRO) in Ahmedabad. In Orissa, on 1st August 1975, the then Chief Minister Mrs. Nandini Shatapati inaugurated the satellite education program at village Ankarantipur in Dhenkanal district.
It serves selected villages of Dhenkanal, Sambalpur, Balangir, Kalahandi, Sundergarh, and Keonjhar districts.
Usefulness
The usefulness of TV certainly extends far beyond radio. TV is the best medium for mass education about public health, sanitation, advanced farming, indigenous industries, small savings, family planning, and personal hygiene. It is the best medium of mass education in literacy and elementary science.
It is also the best medium to teach higher science and geography to students in colleges and universities. It is also the best medium of audio-visual entertainment through songs and broadcasts. It is also the best medium to convey to us the tragedies of war, the havoc of nature, and the development works going on in the country and abroad.
Conclusion
The government of India is trying to provide and popularize TV facilities all over India. People should cooperate with the government to make the best use of this offer. Because television also brings a wealth of sight and a wealth of sound to the television audience.
