Television

media type="custom" key="3846633"Television By Thomas Have you ever wondered how the television was invented? Or how it works? There were two very important people that made television possible, Vladimir Zworykin and Philo T. Farnsworth. They were two very important electrical engineers. Philo T. Farnsworth was 14 years old when he got the idea which triggered the gateway of television. In 1927 Farnsworth started creating the television. He had created the vacuum tube which was called the image dissector. The image dissector was the start of the early TV camera which transformed a picture into radio signals. Vladimir Zworykin was from Russia. He moved to the United States in 1919. In 1923 Vladimir applied for a patent for his iconoscope. The iconoscope was similar to the vacuum tube, because it also changed pictures into radio signals. Unfortunately, Vladimir failed but did not give up. He struggled to get the iconoscope to work. After a lot of hard work in the mid-1930s he finally succeeded.

Before television was invented people had to find other ways to entertain themselves. Many people wrote letters and sent messages to friends and family. People sent messages all over the country that would sometimes be carried by foot and by horse. Before the television was invented one of the main ways of getting information was listening to the radio. Listening to the radio was not only amusing but it kept them connected to news happening all around the world. They also would put on plays which everybody enjoyed. Today the television is one of the main ways of getting information.

The first TVs were almost the size of medium refrigerators. The first TV screens were almost the size of a single piece of printer paper. One of the bad parts of the first TVs were specks of light that drifted across the screen and the screen showed double vision. Televisions were also very expensive. They cost about 1,000 dollars and that was almost equal to a new car! Nine out of every one hundred homes had televisions. In 1955 50% of U.S. homes had TVs.

The television looks just like a box but it is much more then that! The TV receiver shows programs that are broadcasted by companies. The broadcasting stations send pictures and that go to the screen and sound signals go to the speakers. TVs create pictures and sound from the signals they receiver.
