The study describes the role and the representation of popular music in the pre-war dramaturgy of Czech radio broadcast. Having overcome the elementary technical problems, Radiojournal had to consider the needs and preferences of its listeners-licensees and to create a programme scheme that would respect their demands. On the other hand, the management of the radio company from the beginning followed a rather idealistic path of establishing ambitious artistic objectives in the radio`s programme. The whole pre-war period of Radiojournal`s development was accompanied by constant solving of this crucial conflict in the programme`s creation - the one "between the cheap entertainment and the high artistic quality, between the listeners` wishes and the radio management`s conceptions".
