The television

The invention with the biggest impact was probably the television. It was invented by a Scottish man,John Logie Baird. The first televised pictures were sent over a short distance in 1924, and his invention was formally demonstrated at the Royal Institute two years later. The pictures on the screen were not clear, but the viewers could see that they were human faces, and they could see their eyes opening and closing. In 1928, images were sent from Britain to America, and later, to a ship 1,500 miles out to sea. In the same year, the first colour images were sent. The first ‘seeing-in sets’ were sold that same year. For £25 (£1000 in today’s money), people in their homes could watch moving images that were sent from a broadcasting station.
