Television has evolved very fast. Although the history of television has been brief, it has been a very exciting. There are many people in today’s world that have seen the history of television from the beginning to where things are now. There have been many inventors throughput the history of TVs. All these people played important roles that have helped to bring television to the point where it is today. Inventors started working on transmitting pictures onto a screen since the early 1830s. However, it is surprising that the first television waited until the 1900s to evolve.
Early television designs
The first rotating disk TV that made it possible for picture to bee transmitted over wires was invented by a German known as Paul Nipkow in 1884. His discovery led to the development of the first electromechanical TV scanning system in the world. The disk would rate at high speed as light passed through the holes to form a picture on the screen. There have been many developments and many inventions since. In 1924, John Baird invented the first ever picture in motion. Later on, he was able to transmit a human face on a television screen. John Baird contribution to the development of the modern television was enormous.
Vladimir Zworykin invented the cathode ray tube in the 1920s. His invention marked a new era in the history of development of TV. Before his discovery, the TVs that were used were all mechanical. The cathode ray tube technology transformed the TV from being a mechanical device to being an electronic device. Later on, an America farmer by the name Philo Farnsworth got a breakthrough when he found a way to transmit images to a TV screen using 60 horizontal lines. His discovery helped to make pictures clearer. Farnsworth went on to discover 165 more devices, including a dissector tube. The dissector tube was the groundwork for the televisions used today.
People were very excited when the new televisions came into the public domain. However, there are other people who feared televisions because they thought they would transmit their personal conversations. The first televisions were owned only by people who were wealth. They were too expensive for the average people.
The screen of the first television was the size of a dollar coin. The actors who appeared on these TVs had to take turns on the camera because the screen was only enough for one person at a time. The invention of the cathode ray tube made a very big difference. It formed the basis for televisions for close to a century. The cathode ray tube technology made it possible for TVs to be bigger and to display better images. the first color TV was made in 1953. Before then, all TVs were displayed only black and white images.
The invention of the VCR was another major milestone in the history of TV. People were now able record shows and watch them later. The DVD came next. there have been many other developments since. The future of TVs is no doubt bright. Today, people are enjoying clearer and sharper images on bigger screens thanks to 1080P and 4K resolutions.
