A Sensational Scenario: Slow Start, Fast Expansion

2. INTRODUCTION TO TELEVISION
Television is a system for transmitting visual images and
sound that are reproduced on screens, chiefly used to
broadcast programs for entertainment, information, and
education. The television set has become a commonplace
in many households, businesses, and institutions. It is a
major vehicle for advertising. Few inventions have had as
much effect on contemporary American society as
television.
Jeff Greenfield, a media observer, stated “Television is the
pervasive American pass time cutting through
geographic, ethnic class and cultural diversity, it is the
single binding thread of this country, the one experience
that touches young and old, rich and poor, learned and
illiterate.”

3. INVENTION - STORIES
• Philo Taylor Farnsworth (1906 – 1971) was
an American inventor and television pioneer.
• He is best known for his 1927 invention of the
image pickup device, the image dissector, as
well as the first fully functional and complete
all-electronic television system.
• He produced a television system complete with
receiver and camera commercially through the
Farnsworth Television and Radio Co., Indiana.
• John Logie Baird (1888 - 1946) Is Scottish
engineer, the first man to televise pictures of
objects in motion.
• Educated at Larch field Academy, the Royal
Technical College, and the University of Glasgow,
The German post office gave him facilities to
develop a television service in 1929.
• Baird demonstrated color television in 1928 and
was reported to have completed his researches on
stereoscopic television in 1946.

4. HISTORY
• Electronic television was first successfully demonstrated in San Francisco on
September7, 1927. The system was designed by Philo Taylor Farnsworth, a
21-year-old inventor who had lived in a house without electricity until he was 14.
While still in high school, Farnsworth had begun to conceive of a system that could
capture moving images in a form that could be coded onto radio waves and then
transformed back into a picture on a screen. Boris Rosing in Russia had conducted
some crude experiments in transmitting images 16 years before Farnsworth's first
success.
• Also, a mechanical television system, which scanned images using a rotating disk
with holes arranged in a spiral pattern, had been demonstrated by John Logie Baird
in England and Charles Francis Jenkins in the United States earlier in the 1920s.
However, Farnsworth's invention, which scanned images with a beam of electrons, is
the direct ancestor of modern television. The first image he transmitted on it was a
simple line.
• Few inventions have had as much effect on contemporary American society as
television. Before 1947 the number of U.S. homes with television sets could be
measured in the thousands.

5. TV INVENTION PERIOD (1925 – 1959)

6. • The technical standards for modern television,
both monochrome (black-and-white) and color,
were first established in the middle of the 20th
century. Improvements have been made
continuously since that time, and
television technology changed considerably in
the early 21st century.
• Much attention was focused on increasing the
picture resolution High Definition TV and on
changing the dimensions of the television
receiver to show wide-screen pictures.

8. DOORDARSHAN

9. • While looking at this impressive contemporary scenario, one cannot imagine the very
modest start that Indian television had in 1959. The epoch-making day was
September 15, 1959.
• This dry spell lasted twelve long years, till Doordarshan’s second TV Centre came up
at Bombay in 1972. As the first step, urban community-viewing centers, called
tele-clubs, were established in different parts of capital before common citizens.
• This led DOORDARSHAN to take new initiatives in the field of formal education.
India’s first School Television (STV) was introduced in October 1961.
• Meanwhile, a special service, directed to farmers, ‘Krishi Darshan’, was launched
from Delhi on January 26, 1967.
• The late Prime Minister Indira Gandhi’s address to the nation on August 15, 1982
was Doordarshan’s first direct color transmission over the national network.
INDIAN TELEVISION IN RETROSPECT

10. Television has been an integral part of our
lives. It has influenced our lives in so
many ways. We have been now addicted to
this mode of entertainment. This has
resulted in positive and negative
influences. The availability of multiple
channels in regional languages has made
television more popular than any other
medium. And the program producers of the
channel cater to the needs of the people
after understanding the taste
requirements of their audiences.
IMPACT OF TELEVISION IN OUR LIVES

11. • The important change happened is the usage of different ways to deliver TV
programs. Earlier that was satellite relied antennas, now had switched to dishes
other methods of delivery include distribution through cable networks and direct
broadcast satellite.
• Now we can watch TV programs even on our mobile phones. The technology behind
this is called Internet Protocol TV. The advent and popularization of television and
computer have resulted in a revolutionary change and access to everyone to the world
of entertainment.
NEW TRENDS IN TELEVISION

12. Despite this continuous technical
evolution, modern television is best
understood first by learning the history
and principles of monochrome television
and then by extending that learning to
color. The emphasis of this article,
therefore, is on first principles and major
developments—basic knowledge that is
needed to understand and appreciate
future technological developments and
enhancements.
