Abstract Objective Drawing on the theory of polymedia and on the role of information and communications technology (ICT) in (re)defining the articulation between the private and the public, this introduction reflects on what ICT does to and for families around the world. Background Through the development of networking platforms, video call applications, personal sites, and collaborative information platforms, ICT has changed the way people live, love, and interact. It has also afforded new ways to “do family.” Method By featuring studies from a variety of national and regional contexts (Canada, Chile, Ghana, Greece, Moldova, South Korea, Ukraine, the Netherlands, United States, and Turkey), it establishes a dialogue between disciplines and a fruitful cross-fertilization of research topics, methodologies, analyses, and theoretical perspectives. Results This special issue explores (a) the nexus among family life, relationships, and ICT and (b) the relation between the everyday lived experiences of family members and the broader social structures that circumscribe the width and breadth of those experiences. Conclusion The contributions show the porosity of the boundary between public and private spaces. Alternative forms of expertise and parenting norms are emerging online. ICTs are integrated into parents' information-seeking and sharing practices, and emotional support. They sustain relationships between family members across distance. However, inequalities regarding access to the Internet and computer literacy still jeopardize digital citizenship and democratization. Implication The contributions in this special issue highlight the need for better structuring of interventions and policies to support families by using up-to-date ICT systems and creating mentorship programs and digital mediation for family professionals and beneficiaries
