Some say that radio is the theatre for the blind. But is this true? Why do people tend to tell stories using sound alone? Can you capture your life on a tape? If so, is it a documentary for the blind then? And is it possible to create an epic, yet very intimate and emotional tale when your only tool is the spoken word and sounds from everyday life? The author of this thesis regularly visits the International Feature Conference (IFC), one of the biggest worldwide meetings of documentary producers, to find out more about publicly seldomly known genre of radio documentary. IFC is a unique platform where you can listen to productions from all over the world and discuss the tools, topics and rules of broadcasting and share inspirational ideas about recording. The founder of IFC is Peter Leonhard Braun - the first man who used the stereo technique in his documentary production during the 60s. Based on interviews with Braun (and other relevant speakers) the study deals with the phenomenon of radio documentary and its detailed characteristics. The aim of the work is to explicate certain specifics and dissimilarities in the radio production worldwide, to describe how different countries use the basic tools of documentary making and to show the importance of this kind of production. The author demonstrates the development of a radio documentary worldwide on the model of IFC. During the presentation titled "Radio documentaries in the reflection of the International Feature Conference", Tereza Reková talks about the community of radio producers, the rules of IFC, the history and influence of the conference. She also plays short excerpts of interviews she recorded with important radio producers from Germany, Belgium, the United Kingdom, Austria and Denmark. All of these producers speak about their point of view on documentary production, which is different in every country - as each nation has its own traditions and ways of storytelling. The 10th edition of the conference MIRDEC (Masters International Research & Development Center) took place on 6. - 8. November 2018 in the Hotel HCC St. Moritz in Barcelona. The main topic of the conference was Global and Contemporary Trends in Social Science (Global Meeting of Social Science Community).
