1 janv. 1927 - 1927: Television

Description:

After the development of radio, the transmission of an image was the next logical step. Early television used a mechanical disk to scan an image. As a teenager in Utah, Philo T. Farnsworth became convinced that a mechanical system would not be able to scan and assemble images multiple times a second. Only an electronic system would do that. In 1922 the 16-year-old Farnsworth worked out a plan for such a system, but it wasn’t until 1927 that he made the first electronic television transmission, a horizontal line.
