Divulgação científica e ensino de ciências por <i>podcasts</i>: o caso do IFFcast

The popularization of scientific knowledge is an important tool capable of endowing citizens with skills that allow for the analysis and evaluation of situations inherent in decision-making regarding political, social, scientific, environmental, and other issues. In this context, the IFFcast podcast program is born with the objective of democratizing knowledge that often remains restricted to the academic community, combating science misinformation, pseudosciences, and promoting scientific outreach. Since 2019, IFFcast has released 99 original and unpublished episodes on major streaming platforms of its genre. Therefore, this article aimed to profile listeners based on statistical metrics provided by the Anchor platform, responsible for distributing the episodes, mainly mapping age groups, thematic preferences, and gender diversity of the audience reached. The results show that there is gender parity in reach between men and women despite the majority of this format's audience being male. The most representative age group is composed of individuals between 28 and 34 years old. Although the promotion of new IFFcast episodes involves different strategies and social media, 55% of shares occur through the WhatsApp social network. Lastly, it is evident that podcasts are successful digital formats for scientific outreach, demonstrating a consolidated presence on streaming platforms of this genre, although numerous epistemological obstacles still need to be overcome.
