History of Television

Paul Nipkow in 1884 developed the first electromechanical television scanning device. This technology was based on a spinning disk which rotated before a moving image to capture it. In 1924 John Logie Baird invented the first mechanical television; he based his ideas on Nipkows work and developed it further. The concept of the first electronic television system was invented by Philo Farmsworth in 1927; he was just fourteen years old at that time.

The dissector device he developed transmitted current to a cathode ray tube and reproduced images by scanning it onto a fluorescent surface. The cathode ray tube is a picture tube found in all electronic television sets. It is based on the concept where images are formed when an electron beam strikes a phosphorescent surface. He transmitted the first image which was of a dollar sign.

At the same time Vladimir Zworykin develop a cathode ray tube called the kinescope and a television system called the iconoscope. The first long distance public television broadcast was an image of Herbert Hoover and it took place between Washington D.C. and New York City in 1927. Guillermo Camarena invented the color television and sent the first color transmission from his lab to the offices of The Mexican League of Radio experiments. The first electronic color televisions were invented in 1950 along with the remote control.

In 1936 AT&T set the first cable lines to transmit television signals between New York and Philadelphia. NBC started the first television station called W2XBS in the 1930’s. The early television sets had only 12 channels and nobody could have imagined at that time that more than 12 channels could ever exist. The television has made the world a smaller place, not only has television developed in the number of channels but also to broadcasts in other languages and to the birth of cable network.
