This article expounds an approximation to the characteristics of the radio’s morning shows for juvenile audiences, reconstructing the general trends of its structures which, like a merry-go round, offer a constant mix of music, advertisements and conversations that tend to sexualize all issues. This text is a partial outcome to the Observatory over the effectiveness and sexuality in the programming of radio shows for juvenile audiences, supported by the Ministry of Education; hence the first section oi the article is a panoramic overview of the theoretical and methodological approach towards the search for the mechanisms that reveal the characteristical mobility of the evanescent radio discourse.
