This chapter summarizes the main themes associated with relationships between digital technology and society. It first proposes four central characteristics of digital technology that differentiate this concept from the more general term “information society.” Then it maps the growth of the use of terms associated with digital technology in articles in academic databases from 1972 through 2018, and in books from 1967 through 2008. However, the main focus is on summarizing the emergent themes associated with 89 recent books on digital technology society: (A) theory and conceptualization of this vast social change; (B) technology (venues and characteristics), (C) issues (content, creation; big data; civic issues; participation, engagement; inclusion, exclusion, discrimination; ethics, ethical issues; and managing the digital experience), (D) contexts (digitization of self and others; health; relationships; user groups; culture, everyday life, education, learning; work and organizations; and law, policy, regulation), and (E) effects (negative; positive; societal; contradictions, paradoxes, tensions, unintended). Finally, it describes the origins and motivations for this handbook and its main themes.
