History of Television


Television is one of the blessings of modern science. Today almost every house has a television set. Some have also two or more. In this modern era, we cannot think a single day without television. It’s a very important part of our day to day life. To see the world, to know the unknown, to get latest news of the world, to get some entertainment etc. we use this technology. This technology has not been invented overnight. It has a long history of invention.



Electronic television was first successfully invented by Philo Taylor Farnsworth in San Francisco on Sept. 7, 1927. Farnsworth had accepted a system which had the ability of moving images in a form that could be coded onto radio waves and then transformed back into a picture on a screen. 16 years before Farnsworth's first success Boris Rosing in Russia had some barnyard experiments of image transmission. Earlier in the 1920s John Logie Baird in England and Charles Francis Jenkins in the United States had also demonstrated a mechanical television system that could scan images using a rotating disk with holes arranged in a spiral pattern. However, Farnsworth's discovery of images scanning machine which used a beam of electrons is the actual founder of present television. In 1897 German scientist, Karl Braun invented the cathode ray tube oscilloscope (CRT) which is the picture tube found in modern TV sets. Electronic television is based on the development of this cathode ray tube.


RCA, the radio business company in the United States televised the opening of the New York World's Fair In 1939. This program included a speech by President Franklin Delano Roosevelt, who was the first president to appear on television.  RCA began selling television sets with 5 by 12 in (12.7 by 25.4 cm) picture tubes. Early television was totally undeveloped. All the action had to be captured by a single camera. As the early cameras had trouble with the color white, the actors in dramas were forced to work under impossibly hot lights, wearing black lipstick and green makeup. World War II slowed the development of television, as companies like RCA turned their attention to military production. In the United States full-scale commercial television broadcasting did not begin until 1947. However, the number of television sets in use rose from 6,000 in 1946 to some 12 million by 1951. No new invention came in American homes quicker than black and white television sets. Half of all U.S. homes had one TV set by 1955.
 
Color TV was a new idea which successfully began commercial broadcasting, first authorized by the FCC on December 17, 1953 based on a system invented by RCA. "Rabbit ears", the "V" shaped TV antennae was invented by Marvin Middlemark. Cable television, formerly known as Community Antenna Television or CATV, was invented in the mountains of Pennsylvania in the late 1940's. The first TV remote control called "Lazy Bones," was developed in 1950 by Zenith Electronics Corporation (then known as Zenith Radio Corporation). The TV remote controller first entered the American home in June of 1956. The American Broadcasting Company (ABC) first aired Saturday morning TV shows for children on August 19, 1950. First prototype for a plasma display monitor was invented by Donald Bitzer, Gene Slottow, and Robert Willson in 1964. Web TV was rolled out in 1996.


So step by step television has been modernized and more attractive to the millions of billions users in the world. Now we can be more connected with the world via television programs. We no more feel bored because we have this entertaining machine to company our leisure time. Assembled with USB ports, we can easily watch movies or view other videos by connecting the device through TV. Whether it is LED or the 3D TV, TV viewing experience for the users have improved giant strides. There has been significant improvement in the television since the time it was first launched. And the improvement has not been stopped; there is a lot to come in near future too.
