In the 1950s the ARD radio services became the major factor of the mass media system in West Germany. As early as 1952 the ARD radio stations had ten million listeners. However, the radio stations operated on a regional level, and it was only the development of a television umbrella that helped the ARD to establish itself nationwide. The broadcasting of a countrywide TV broadcast service was the goal of the ARD from the outset and the go-ahead for this was given at the end of 1952. The same year ARD was admitted as a full active member of the European Broadcasting Union and the "German sound archive", now German Broadcasting Archive (DRA, Deutsches Rundfunkarchiv), was established as a joint facility of the ARD.
