What is a podcast? Considering innovations in podcasting through the six-tensions framework

This essay addresses two questions on the topic of podcast innovation. The first, ‘What is a podcast?’ is answered via a review of the literature, investigating podcasting history and its evolution. The definition of podcasting arising from this analysis – centring on episodic audio, convenient both to produce and experience – takes into account recent changes, providing an up-to-date description of the term, useful for further research on the topic. It is also required to answer our second question: ‘How do we design new ways to produce and listen to podcasts without denaturing the medium?’ By reflecting on the essential features of podcasting and the necessity for innovation in this interdisciplinary medium, a framework of six-tensions is proposed as a means of grounding and potentially boosting innovation. Answering these questions could prove valuable for the future of podcasting, hypothesising a basis for reflection and development in both academia and industry.
