This chapter focuses on the history of four important types of digital technology, including the Internet, digital games (all types of games played electronically), virtual reality, and smartphones (particularly smartphone apps). The authors present a varied and balanced view of different digital technologies, introducing their historical developments as well as an overview of potentially positive and negative applications of each of the technologies covered. Increased governmental support is required for research into digital technologies and those applications that have been established to have beneficial effects for users, but equal effort is also needed in developing new policy, educational, and legislative frameworks that are in tune with the needs of a digital society. Research into digital technology use and its context may enable better control of how interactions with digital technology continue to shape our behavior
