The History Of Television

Television shortly known as TV is a technology enabling transmission of full motion broadcasts to receivers

. It is a device used for watching broadcasts. Nowadays televisions are everywhere in the western world and increasingly getting popular in less developed nations. It is estimated that by the middle of 21st century every home will have at least one television set.

The idea of using television for entertainment happened late in the development of technology. The first use of TV was more useful for telephones, Alexander Graham Bell who was the inventor of telephone created a working photo phone in 1880.There were a number of technologies tested and developed in the late 1800s like radio broadcasts, telephones, use of electricity and personal photography. TV was not an invention of the 20th century and it took longer to develop.

The most significant enabling technologies for television was the cathode ray tube which was invented in 1876. It used electricity forced through a vacuum tube for producing light on the glass front. In 1926, the first broadcast of a picture over remote distances occurred in London. It was credited to John Logie Baird, a Scotsman and Charles Jenkins, an American.

The first television broadcast was basic as compared to this modern era. There was just a moving slideshow of stick figures or photographs. However it proved the technology and was a vital step in the development of full motion. The first electronic system with motion camera and broadcast abilities was demonstrated by Philo Farnsworth in 1927.

The technology of television continued to develop with the passage of time but at a slow speed. Bell Laboratories and RCA actively invested to develop the complete broadcasting and receiving system for commercial gain. The first breakthrough for RCA was in New York in 1939 when it successfully broadcasted the Presidents speech in black and white.

The full development of TV was prevented because of World War II although there was news broadcast. After the war, there was tremendous interest in television from the public desperate for new goods.

The second major development was the introduction of color television in 1960s. It was a revolution that transformed the world and the audiences could see shows, documentaries, musicals and news broadcasts for the first time as if they were right there.

With the availability of color television, the black and white quickly started to disappear. The impact of watching TV started to be felt. The most important contribution of television to mankind is its relative ease of bringing distant people together using satellite uplinks. Cable and satellite television quickly enabled networks to increase their reach across around the world. The high definition television standard with over double the number of lines at 1125 was approved in 1980s. The future of TV may be very different from its early 90s.
