The article consists of two parts. The first examines the impact of the radio on mass communication as well as the way in which this invention was used in the 20th century by governments not only in Europe. The author briefly presents the functions and features thanks to which radio was seen as an attractive medium to disseminate ideas, information and propaganda. Radio used in the process of competing for power is the context in which the author discusses the Polish presidential campaign of 2010. The second part of the article is a case study, an analysis of three selected radio programmes in which politicians present themselves as presidential candidates and seek the votes of citizens.
