As social media scholarship matures, early optimism has been replaced by a more complex and arguably gloomier picture of the role of digital media platforms in our lives. This incisive Research Handbook showcases the academic community’s responses to key societal challenges posed by evolving social media ecologies. Multidisciplinary and international in outlook, leading contributors present wide-ranging and balanced coverage of social media research, including non-Western settings and the Global South. Chapters explore emerging interdisciplinary research methods which support the increasingly sophisticated, theoretical understanding in the field. They also debate the complex ethical issues confronting social media scholars today. Students and early career researchers in communications, digital media and sociology will find this a highly valuable book. Due to its inclusion of diverse contexts and locales, this book will also be of interest to experienced researchers and academics.
