Televisions are a device widely used by people today, this tool was created in 1926. Television was invented by John Logie Baird in 1923 in the city of Hastings, England and the first television image was broadcast by Baird in 1926. The images, which were initially dotted and flickering, were developed by Baird. its price when it came out on the market was USD 457.93, I think because John Logie Baird relied on the transmission of images by waves. The first time something appeared on a television screen was on January 26, 1926. The protagonist was the puppet of an inventor, John Logie Baird. This always believed in the possibility of transmitting images by waves, just like the radio did, these are the images of this device before and after

It is an ancient mechanism for projecting images, in which an entire room performed the same operations as a current photographic camera inside, with the difference that at that time there was no possibility of saving the image unless it was drawn manually. the creator of this tool was an electrical engineer Steve Sasson in Brooklyn, New York, United States and he worked for Eastman Kodak when in 1975 he invented this gadget of electronics, the first digital camera, its price when it went on sale was $351.20, I believe it because when he went with his boss, they persuaded a laboratory assistant to pose for they. You could see the silhouette of her hair that's when she decided to create the digital camera these are the before and after images of this device
