A second screen refers to a secondary electronic device, such as a smartphone, tablet, or laptop, that is used simultaneously with a primary screen, typically a television or computer, to enhance the viewing experience. This allows users to engage with additional content related to the primary screen, such as social media updates, behind-the-scenes information, or interactive features. The concept of a second screen has become increasingly popular in today’s digital age, providing a more immersive and interactive way to consume media and connect with others while watching TV or browsing the internet.
