The white paper from Secondsync presents a comprehensive analysis of television-related discussions on Facebook across the US, UK, and Australia, revealing that most engagement occurs in real-time during show airings, primarily via mobile devices. It highlights that up to 25% of the viewing audience interacts with content on Facebook while watching, and demonstrates distinct engagement patterns based on genre and demographic factors. The findings underscore the significant commercial implications of social media interactions for the television industry and suggest areas for future research.
