The television is one of the biggest inventions over the past century, and there is a great history behind it. No single person can take credit for the invention of the television. The modern television was the result of a number of discoveries in electricity, electromagnetism, and electrochemistry. Some of the important discoveries were found in 1817 with the discovery of selenium, an element that when exposed to light is a strong conductor of electricity. Then in 1878 Sir William Crookes invented the cathode ray tube.
The first working television was made in 1884 by Paul Nipkow of Germany. Nipkow made a mechanical scanning disk which picked up fragments of a picture through small holes and then redrew them onto the light-sensitive selenium tube. The picture was then depicted on a receiver and as a result it was very crude, but it was a start. It was later suggested that the use of the cathode ray tube for the receiver would make the image clearer.
The final important piece of technology that made the television what it is today, was the work of the pioneers in radio-Heirich Hertz, John Fleming, Thomas Edison, and Lee De Forest. They were the ones who developed the methods of broadcasting needed to relay the signals to distant points.
Television technology is constantly changing with LCD, Plasma, and LED Televisions being the latest advances, it is great to know what started it all. With all of these discoveries put together and greater technology was created; the television is a truly astounding invention and has certainly helped civilization advance.
