This second edition of the groundbreaking Routledge Companion to Mobile Media brings together newly commissioned essays and cutting-edge research alongside updated essays from the original volume to create a definitive guide to mobile communication studies. The collection, which brings together original articles by a global roster of contributors from a variety of disciplines, sets out to contextualise the increasingly convergent areas surrounding social, geosocial, and mobile media discourses. Essays provide comprehensive and interdisciplinary models and approaches for analysing mobile media and draw upon a wide range of global case studies, from China, Africa, Southeast Asia, the Middle East, and Latin America to Europe, the UK and the US. This new edition also covers the many changes in the field over the last decade:  from dating apps, AI, mobile phones, travel, games and digital transactions through drones, blockchain, microbilities, virtual reality, touch and haptic technology, to the role of mobile media in health, climate change, mobiles and electrification, digital migrant cultures, arts, creativity and politics-and beyond. This second edition remains an essential resource for upper-level students, researchers and scholars interested in mobile media research.
