In short, this is a visualization and natural language processing project for understanding the "nature of podcasts" and seeing their human listeners through topic analysis.
Podcasts are typically periodic audio-only Internet 'radio shows' that, like any media, act as a lens into the cultures producing and consuming them. Once niche, around 25% of Internet users listen to podcasts
according to the Pew Research Center. Indeed, being online they reach an international community and some also play on typical radio stations.
What is the nature of these podcasts? Can they say anything about their audiences? Can they let us see into emerging cultural trends? This project tries to take a first stab at answering those questions.
