A second screen refers to the use of a secondary device, such as a smartphone, tablet, or laptop, while watching television, allowing viewers to engage with additional content or interact with others about what they are viewing. This phenomenon enhances the overall viewing experience by providing supplemental information, enabling social interactions, and fostering greater viewer engagement through apps, social media platforms, and interactive features. The rise of second screen usage has transformed traditional viewing habits, making it a crucial element in both cable/satellite television and social TV dynamics.
