As part of the advocacy of the Asian Congress for Media and Communication (ACMC) to promote regional studies in global academic discourse, this book contributes to a better understanding of social media within the context of Southeast Asian countries, with the addition of Sri Lanka. The contributors here are primarily Asian academics and practitioners, immersed in the fields of media and communication. Throughout the chapters, the reader will discover that social media has changed the paradigm of communication in the region: as an avenue for free expression; as a tool for news gathering and news distribution; as an aid in crime prevention; and even as a means to find a lifelong partner. For non-Asian readers, there is also an annex that provides a summary of social media statistics in the region to allow the countries mentioned in this book to be situated within the global context.
