This Special Issue examines the relationship between imaginaries and infrastructures. Through a specific focus on the Asian region, the four articles contained herein demonstrate how these imaginaries span, transform and proliferate various boundaries. They also create new regimes of visibility and present a range of ethical dimensions for those who use them and the companies and governments that regulate the infrastructures. These include dating and video sharing apps, digital money transactions and diverging historical accounts of communications technologies. Such diverse examples demonstrate how media infrastructures and the media content they carry enable the production of imaginaries and meaning.
