Shortly after the Nazi seizure of power in January 1933, Hadamovsky served as the National Programming Director for the German Deutschlandsender broadcaster.[1] A few months later, he was appointed Reich production director and head of the nationalized Reichs-Rundfunk-Gesellschaft, whereby he played a vital role in the Nazi Gleichschaltung of the incorporated regional broadcasters. In 1935 he initiated the launch of the Fernsehsender Paul Nipkow TV station.
