On 2 November 2009, the Southern German radio station SWR2 broadcast a feature in the rubric "Wissen" (Knowledge) entitled Gemein-Freiheit. Vorboten einer freien digitalen Kultur (In the public domain. Precursors of a free digital culture). The programme deals with the question of freedom of thought and knowledge and focuses on Open Content, Creative Commons, the public domain and Open Access. It is well worth listening to.
