Impact of TV on ME

I've learned a lot from watching television. I learned how to speak English and other languages. How do I protect myself? How to invent stuff? I learn about places. I learned how to dance.

TV is also good because during my free time I can watch movies. It helps me to relax. If I didn't have a TV, I would be bored.

what tv will look like in 10 years from now?

In 10 year tv will look like a I-pod touch, you can take it in your pocket, with a strong battery and solar , and you can watch anything you want for free.

Why was T.V Invented?

Television was the next logical step beyond radio. People used to sit around and listen to radio sitcoms like we watch TV shows. The next logical step beyond being able to only hear them was being able to see them. The TV like the radio was invented so the government could commincate over a long distance with its moving armies, but unlike the radio this way they would be able to sea each other face to face. It was a way of communicating life ideas. The TV was invented so people could be entertained by actors and watch people living dream jobs. Also, the TV can be used for education, like the Discovery Kids channel and the National Geographic channel. Television was invented for the advancement of society. It is not the inventor's fault if a creation meant for family entertainment is often used in a detrimental way. It was a simple act of the government. At the time TV was created, the government wanted to get the message of fear out to the public on a broader.

The modern television was only made possible with the scientific advances of the early 1900s, which included significant developments in radio, x-rays, and physics. Wireless transmission of sound became possible with the invention of the radio at the turn of the century. But the critical component necessary for the high-fidelity projection of reconstituted light information was the cathode-ray tube, originally used to produce x-rays for medical purposes. In 1906, I found that manipulating the electron stream of the cathode-ray tube with a magnetic field was possible. Less than a year later, it was suggested that the cathode-ray tube be used as a receiving device for images. Im a Russian scientist,i quickly created such a cathode-ray tube and encouraged further development of the technology.

Rosing's student, Vladimir K. Zworykin, migrated to the United States after WWI and created the "iconoscope", a device that scanned an image with an electron beam and converted it into electronic signals for transmission. To minimize the amount of data needing to be sent, he fed the image through a "mosaic" - a plate covered with microscopic photosensitive dots we now know as "pixels". The information was then broadcasted and received by a device that ran the process in reverse, using the cathode-ray tube to project images far more quickly and effectively than the mechanical televisions of the past. The first incarnation of the modern TV was born. It was successfully demonstrated in a public context in 1929.
