大象传媒

Michael Mosley, Cassie Newland and Mark Miodownik from the 大象传媒 series 'The Genius of Invention' describe the scientific achievements of John Logie Baird. In 1920 we had invented cinema and then radio. Scientists and inventors were racing to work out how to combine them into television.

John Logie Baird created the first prototype from four inventions from other people (all described) to develop the first mechanical television. In 1925 he sent the first television image of a ventriloquist's dummy across a room.
