Amsterdam is home to the second-largest Dutch commercial TV group SBS Broadcasting Group, consisting of TV-stations SBS 6, Net 5 and Veronica. However, Amsterdam is not considered 'the media city of the Netherlands'. The town of Hilversum,  south-east of Amsterdam, has been crowned with this unofficial title. Hilversum is the principal centre for radio and television broadcasting in the Netherlands. Radio Netherlands, heard worldwide via shortwave radio since the 1920s, is also based there. Hilversum is home to an extensive complex of audio and television studios belonging to the national broadcast production company NOS, as well as to the studios and offices of all the Dutch public broadcasting organisations and many commercial TV production companies.
