Transpodcast universe. Narrative models and independent community”.

This article describes the evolutionary process and the state of the art of podcasting from a theoretical and analytical perspective. This work integrates the main results of several researches carried out by the author in different countries, whose main conclusions show that podcasting has acquired a transmedia narrative texture that goes beyond the monomedia model from its beginnings, giving way to a new medium, transpodcast, which presents complex structural systems characterized by a specific multiplatform grammar and a high diversity of contents. Transpodcast is supported by the development of robust affinity communities, users and fans. These communities are built as peer-to-peer communication spaces and algorithmic environments where an evident automation of the fandom takes place.
