The Television

Eadweard Muybridge created the first motion picture when he recorded a racehorse and his rider with 12 cameras. He then put these images in a Zoopraxiscope (which was invented by him) to create the animation. The Zoopraxiscope, invented in 1879, used spinning motion to make the impression of movement within the image. This was the dawn of filmmaking. In 1885, George Eastman and William H. Walker created the first reel of film. The reel's material will soon be changed to a synthetic plastic, celluloid. Edison would then invent the Kinetoscope, which could play the recorded material on a reel. It was invented August 31, 1897, though the true inventor would be William Kennedy Laurie Dickenson. The Kinetograph was also invented by William as a better device to record films. It would be used the same way as camera, except with reels instead of paper. This would lead the Lumière to make a better recording device, the Cinematograph. It could create better and clearer images than the Kinetograph.

The first camera to keep a permanent image would combine the camera obscura and of chemistry. Using substances such as silver chloride to retain the light shined in by the camera obscura. It would be in the year 1826 that Joseph Nicephore Niépce would create that camera. Using a method called the daguerreotype process, which he discovered, he was able to keep an image on a plate of metal. It would later be imprinted on paper using a printing press. However, the process took too long. The first picture took eight hours to be imprinted on the plate. However, Alexander Wolcott would then change the design so that the image could be registered directly on paper. Innovation would then lead to shorter exposure time, sharper images and colour.

The inspiration of the television probably started when man started seeing. The vivid colours that they saw would only be recorded in their memory, but how to share it? You could talk about it or write about, but it's not the same feeling. So the first paintings started to show up on cave walls. Painting was the only way to preserve and share the information in the image the most efficiently. However, time and effort were required and special care to prevent from letting the painting from being ruined. It will not be until the invention of camera in 1826 that images could be preserved. However, a technique in China was being used called "camera obscura" would lead to something like the first film. Using the light from an external area and having it enters a small hole, we could produce an image. These functions like the human eye. However, the image was inverted, it would not be until the 1700s when they would use mirrors to fix the effect.

The television is an extraordinary device. It has helped change world history. For example, the invention of the cathode tubes would create radar. This radar would then be used against the Germans in World War II as they attempt to bomb cities. The television is also a way to communicate information that the radio could not do. Sounds can give part of the information from the scene, but the image gives even more with the sounds. The television is a device that has innovated and probably influenced the invention of the computer and internet. Without the television, the world would not be the same.

Paul Julius Gottlieb Nipkow created the Nipkow disk in 1884. It was a rapidly spinning disk with holes in a spiral form that would quickly scan each line of the image. The disk would lead to the mechanical television. In 1925, John Logie Baird used the Nipkow disk to create the first mechanical television. He was able to transmit the picture of not only of an object, but of a person as well. Soon, the mechanical television had the electric television as its rival. Created by Philo Taylor Farnsworth on September 7th, 1927, the device used cathode tubes to display an image. In 1928, John performed the first transatlantic broadcast of his device to boost popularity. However, the quality, range, price and size of the electric television would overtake the mechanical television as inventors like, Vladimir Zworykin improved the electric television instead of the mechanical one. With time, the television will become flatter yet larger in height in length with vivid high definition colours creating new market opportunities for the TV manufactures and those who produce content for it.

The television is a device that can receive images and animations from signals and wires. The television would be the next milestone in the information age as we move away from just sending sounds to sending sounds and images through signals. This technology will also make the invention of the computer, the internet and many gaming systems possible as they require the ability to send the images through signals. It helps share information quickly and efficiently through broadcasts of news, entertainment, advertising, etc. The television influenced the way we send and share data.
