Under the supervision of the United States Information Agency from 1965, the station was staffed almost entirely with German employees, who worked under a small American management team.
RIAS-TV, began broadcasting (as a part-time optout on the terrestrial frequency of SAT.1) from West Berlin in August 1988, which also acquired the German Educational Television Network in United States.
