In the media environment, on-demand content is becoming more and more prevalent. Radio is also evolving and is increasingly offering this type of content. However, radio has not been sufficiently appreciated as a medium and this has resulted in a low scientific production. Within this new model of radio convergence, this article aims to review the state of the scientific literature linking radio and podcast. Methods. The article presents an exhaustive review of the literature on podcasting and online radio, based on the review of the most cited journals listed in Scopus and WOS (Web of Science). Based on the systematic literature review technique, we formulated hypotheses related to the number of published articles, journals and countries of publication, language of articles, authors' affiliation and impact factor. Results. There is a low incidence as far as production is concerned. An initial search revealed 91 articles, of which only 28 became part of the sample based on their subject. Almost all of the articles are written in English and are produced in English-Speaking countries, and Radio Journal is the publication that offers the largest number of articles on the subject under study.
