The story
The ADN was established in October 1946 as a GmbH (limited liability company) with the support of the Soviet Military Administration in Germany. In 1953, the GDR's ruling Socialist Unity Party (SED) ordered ADN GmbH dissolved and converted into a government agency with a monopoly on national and international news coverage. Although the ADN was officially subordinate to the Council of Ministers, the SED maintained a careful watch over it as the most important means of disseminating news to the public. In 1956, ADN assumed control over formerly independent photographic agencies in Berlin under the name ADN Zentralbild (ADN-ZB – German: Central Picture).
According to the ADN statute of 1966, its task was to report news in light of the ruling party's program, resolutions of the party's Central Committee and regulations issued by the GDR Council of State and Council of Ministers. Until the end of the 1970s, ADN compiled and distributed news via teleprinters. The ADN began converting to electronic text processing and transmission in 1979, using technology purchased from the Kyoto-based Omron Corporation.
Up to 1989, ADN employed approximately 1,400 people. It did not survive for long after German reunification in 1990. In May 1992, reduced to a staff of 254 and unable to compete with West German news services, the firm was sold to the Deutsche Depeschendienst (German Telegraphic Service). The collection of approximately one million historical photos preserved by ADN Zentralbild, some dating back to the earliest years of photography, were acquired by the German Federal Archives in Koblenz.
