This open access book outlines how the digital platforms that mediate so many aspects of commercial and personal life have begun to transform everyday family existence. It presents theory and research methods to enable students and scholars to investigate the changes that platformization has brought to the routines and interactions of family life including intergenerational communication, interpersonal relationships, forms of care and togetherness. The book emerged from a seminar jointly funded by the Collaboration of Humanities and Social Sciences in Europe project, the Norwegian Research Council and The Australian Centre of Excellence for the Study of the Digital Child.
