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."
