Second screen

For the use of multiple computer screens, see Multi-monitor.

A second screen is a computing device used with two screens to provide complementary or interactive content. The term most commonly refers to using a smartphone or tablet computer while watching television, where the second screen displays related content such as social media discussions, polls, additional information, or interactive features synchronized with the broadcast.

Second screen technology is designed to increase audience engagement and has been found to support social television by generating online conversations around specific content. The term can also refer to multiple monitors connected to a single computer for productivity purposes.
