In the 2010s, as chat apps became a primary mode of communication for many people across the world, WhatsApp quickly outpaced rival messaging apps and developed into a platform.In this book, the authors provide a comprehensive account of WhatsApp's global growth. Charting WhatsApp's evolution from its founding in 2009 to the present day, they argue that WhatsApp has been transformed from a simple, 'gimmickless' app into a global communication platform. Understanding this development can shed light on the trajectory of Meta's industrial development, and how digital economies and social media landscapes are evolving with the rise of 'superapps'. This book explores how WhatsApp's unique characteristics mediate new kinds of social and commercial transactions; how they pose new opportunities and challenges for platform regulation, civic participation and democracy; and how they give rise to new kinds of digital literacy as WhatsApp becomes integrated into everyday digital cultures across the globe.Accessibly written, this book is an essential resource for students and scholars of digital media, cultural studies, and media and communications

"From New York Times bestselling coauthor of The Coddling of the American Mind, an essential investigation into the collapse of youth mental health-and a plan for a healthier, freer childhood After more than a decade of stability or improvement, the mental health of adolescents plunged in the early 2010s. Rates of depression, anxiety, self-harm, and suicide rose sharply, more than doubling on most measures. Why? In The Anxious Generation, social psychologist Jonathan Haidt lays out the facts about the epidemic of teen mental illness that hit many countries at the same time. He then investigates the nature of childhood, including why children need play and independent exploration to mature into competent, thriving adults. Haidt shows how the "play-based childhood" began to decline in the 1980s, and how it was finally wiped out by the arrival of the "phone-based childhood" in the early 2010s. He presents more than a dozen mechanisms by which this "great rewiring of childhood" has interfered with children's social and neurological development, covering everything from sleep deprivation to attention fragmentation, addiction, loneliness, social contagion, social comparison, and perfectionism. He explains why social media damages girls more than boys and why boys have been withdrawing from the real world into the virtual world, with disastrous consequences for themselves, their families, and their societies. Most important, Haidt issues a clear call to action. He diagnoses the "collective action problems" that trap us, and then proposes four simple rules that might set us free. He describes steps that parents, teachers, schools, tech companies, and governments can take to end the epidemic of mental illness and restore a more humane childhood. Haidt has spent his career speaking truth backed by data in the most difficult landscapes-communities polarized by politics and religion, campuses battling culture wars, and now the public health emergency faced by Gen Z. We cannot afford to ignore his findings about protecting our children-and ourselves-from the psychological damage of a phone-based life"--
