EOTO Com Tech Timeline Peer Review

During peer presentations what caught my eye was the information presented about the first television. At the end of the 1920s there were only a couple dozen televisions in the world which at the time were huge (basically covered the entire wall) which were all placed in research labs. It started at a RCA research lab and is now in almost every Americans living room. It was invented in 1928 by Philo Taylor Farnsworth who invented the first all-electric vision image. The original use of a television was delivering images to a screen and the first system broadcast was a straight-line photo, and the footage was seen in black and white. Philo wanted a tube that could somehow electronically show images by shooting a beam of electrons against a light sensitive screen. The TV got its name television meaning a device that mechanically scanned an image through a spinning disc with holes cut into it that is able to project tiny reproduction of what is being scanned on a screen. Without TV today we wouldn’t have Ellen, Netflix and my current major would definitely not exist.
