A major principle of Archivradio is that original sounds are unedited and played back in full length.
Typical topics in the past have been original recordings by the East German secret police Stasi, the complete proceedings of the first literature congress in Berlin after World War II (Erster Deutscher Schriftstellerkongress) or sounds from World War I, most of them recorded on Phonograph cylinders.
The internet radio consists mainly of spoken word and only broadcasts music in a specific context.
Archivradio was initiated by the German public radio journalist Maximilian Schönherr and his colleague at SWR Detlef Clas in summer 2007.
In several cases audio segments aired via Archivradio created spin-offs like radio documentaries.
