Television
1927 |
Television is the most popular way people get their news and entertainment today. Could you imagine what the world would be like without television? Unlike most of the world's major inventions, hardly anyone knows who created television. His name was Philo Farnsworth. In 1927, Philo, who was only 20 years old, sent the first all-electronic image in his own lab in San Francisco, California. The image was a simple black line that was being rotated to see if the television could record and reproduce its movement. The first television didn't have any sound. Philo loved inventing. He invented many other things, such as the idea to use radio waves to detect things (which later became radar), the baby incubator, and black light, which makes white things look as if they're glowing. It wasn't until the early 1950s that people in Canada could buy a television. The first televisions were black and white, and there were only a couple of channels. A few years later, people could buy colour televisions. CBC Television began broadcasting in colour in 1966. |
