This book is a unique and timely collection that breaks ground on how discourse scholars, coming from a range of disciplinary perspectives, can critically analyse different social media, including YouTube, Facebook, Twitter, and News. The collection gives a thorough overview of the field to date, and draws on different traditions in discourse studies, showing how different forms of social media can be analysed and dealt with critically. A significant contribution to the field, this book will be a go-to resource for social media scholars and students. This book was originally published as a special issue of the Journal of Multicultural Discourses.
