In the last decades we have seen a transformation of our reality, each day more and more influenced and linked to the digital world. No one doubts that we are experiencing a profound change that, supported by new technologies in a massive way, offers us great opportunities and challenges.
We could say that mobile devices and the internet have been the two key elements that - as the printing appearance caused, or later other mass media, such as radio or television - reaches absolutely all the spheres of our lives: communication, information, entertainment, commerce, the provision of education, health and government services, and the production systems themselves. These elements not only provide new tools, but also influence our position in the world, in our role as citizens.
Thus, although the concept of "digital citizen" was initially created to define those people who were active on the Internet and who used it to interact with their public administrations or collaborate with social and political entities, this idea become obsolete, and it is now clear that digital citizenship is no longer a matter of choice, but there is a digital space in which all citizens must be present.
