Television has been definitively dematerialized, transforming itself from a simple medium format: today the television screen is therefore only one of the many accessible, while the sources for accessing films and video content are multiplying. Watching an online TV series is no longer a taboo, accessing streaming hd is a widely accessible thing and smart TVs have become the new elected tool for installing apps for video on demand use. YouTube and Netflixare the two new paradigms for watching movies in streaming, revolutionizing usage habits and business models related to production, distribution and advertising. A historical revolution, with which the Web has appropriated part of that leadership that TV has kept for over half a century.
