This book, written by Mariana Marcelino Silva, a young teacher who mentions in her observations, the inflection of the contact of technology between adolescents and their families. The referential data described in the pages of this book balances the events of the decade from 2010 to 2020, how the relationship between families is being conducted with the use of digital technologies, and how digital media are increasingly being discussed in our society. This makes education a quality method for exploring the coexistence of digital devices in the family environment, including the behaviour of family members. There is a concern about the reach of communication and education through socio-digital behaviour. We will see in the manuscript how technology has been inserted into society until the moment when we are moving towards the Post-Digital Age, and we will observe how it has become a protagonist in everyone’s life, transforming, educating or diagnosing pathologies. Technology has been the great viewer of contemporary society.
