Deutscher Fernseh-Rundfunk Wikipedia
Deutscher Fernseh Rundfunk (German Television Broadcasting) was a German television service that first aired on 22 March 1935. It used an early electro-mechanical system, based around the intermediate film technique and the Nipkow disk, at a resolution of 180 lines.
Transmitting from Berlin, via the Fernsehsender Paul Nipkow, initially three times per week for ninety minutes, it was on air until November 1944. However, as television sets were expensive in the mid-1930s, and few were privately owned, the service was mainly viewed in public television parlors (fernsehstuben) within the service area of Greater Berlin.
