A second screen application is a digital tool or software that enhances the viewing experience of a primary screen, such as a television or computer, by providing supplementary content and interactive features on a secondary device, such as a smartphone or tablet. This allows users to engage with the content in a more immersive and personalized way, whether it be through live polls, behind-the-scenes footage, or social media integration. Second screen applications have become increasingly popular in the age of multi-tasking and on-demand entertainment, providing a seamless and dynamic way to consume media.
