Many people may think that talking about video is a very new technology. But it is not as new technology as you might think. During his work for the German Post, G. Karawinkel developed the first videophone system, which was able to transmit both audio and video in both directions, and introduced the invention at the Berlin Radio Fair held in the summer of 1929. The device was later removed from the Deutsche Museum in Munich, and from 1930 until 1945 it was introduced in this museum. On May 19, 1932, the television phone in Baird, England, was introduced by H.J.Barton-Chapple in Paris. A team of buyers was placed in the bureau of Le Matin newspaper and another in Lafayette Galleries. People in two different places, during the trials they performed, managed to see each other.
