Reply to comment by BailoutBill in TIL The inventor of the television was a 15 year old farm boy who got the idea for scanning an image in rows from the back and forth motion of plowing a field. by chapstickninja
The Baird system used spinning discs with holes at progressively different radii so that the as the disc spins, the holes trace curved lines progressively across the image. The disc in the camera and the display have to be synchronised. The system is different from the method that eventually caught on, but the principle of progressively scanning an image line by line absolutely is a feature of the Baird system.
