According to codified terminology, Second Screen refers to all devices other than the television – such as tablets, smartphones, or personal computers – through which users access audiovisual contents or services that can enhance or enrich the TV viewing experience (e.g., social media). The Second Screen is an evolution in the multimedia ecosystem that has now revolutionized the way television is made and watched. The metamorphosis of TV is not only materializing through image quality with High Definition or UltraHD but also in the multiplication of screens, with the Second Screen being the most evident demonstration. Observers point out that this is not just a generational phenomenon: while for so-called “digital natives,” the Second Screen has become a First Screen, the preferred means to view content and share the experience online, the simultaneous use of tablets or smartphones while watching television is becoming widespread among a large part of the TV audience.

For traditional broadcasters, this presents an additional challenge: not only from a technical perspective but also from an editorial one. To be more engaging for the audience and more appealing to advertisers, a program must include, besides the classic television format, a second level of consumption, whether simultaneous or not, non-linear, multimedia, and possibly interactive, that runs on a Second Screen.
