Social media’s influence extends far and wide. Sometimes it is a force for good and other times it is a force for misinformation or spreading malice. One area on the plus side of the equation is education and a specific area of education that receives considerable attention is science and technology.
To mark the contribution of educators to social media, the organisation World Congress of Science and Factual Producers (WCSFP) has announced an event titled Congress ’25, which is to take place this December 8-11 in Rio de Janeiro.
WCSFP is a not-for-profit, member-driven organisation where science, history and natural history content creators and executives can share, explore and reveal how advancements within these industries are communicated to the world. This includes using digital technology and forms of new media to communicate content designed to educate and to entertain.
Evolution of factual storytelling
Congress ’25 promises is a convention designed to provide opportunities for producers, broadcasters, and digital innovators to explore new markets, connect and collaborate, and experiment with fresh formats. This includes charting the evolution of factual storytelling as well as exploring the growing intersections between television, film, and digital platforms.
Included in the lineup is Dr. Derek Muller, creator of Veritasium, one of the world’s largest and most influential science YouTube channels. With almost 19 million subscribers and billions of views, Muller has transformed the way audiences worldwide engage with science. Muller’s keynote speech will set the stage for Congress ’25, spotlighting how creators are reshaping factual storytelling and audience engagement.
Muller is well-suited to the task; his doctoral thesis was titled Designing Effective Multimedia for Physics Education.
Another speaker, from Los Angeles, is Kevin Allocca, Global Director of Culture and Trends at YouTube, whose role places him at the heart of understanding what drives billions of video views daily. His perspective is important in the context of platforms and audience habits are shifting rapidly, creating new opportunities for factual producers worldwide.

The third person to be announced is Mariana van Zeller – journalist, host, and executive producer of the Emmy Award-winning National Geographic series Trafficked. van Zeller will share first-hand insight into the risks and rewards of immersive investigative reporting.
