Resumen: Despite the potential of interactive video and sophisticated new narrative choices beyond the sequential asymmetrical restrictions encountered in historical analogue modes of AV representation, online science video has not (yet) lived up to the promise. In their conclusion, León and Bourk discuss several reasons for the limited presence of interactive innovations in online science video content, including the migration of television content and production sources to the Internet, as well as the low production quality of much user-generated content opting for more `authentic¿ amateur-styles that suit limited budgets. Notwithstanding the limited evidence of innovation, there are encouraging developments including vlogs, webdocs and animated video, such as stop-motion innovations, ideally suited for short-length formats.
