This book discusses how various social marketing campaigns have taken up and had an impact on important aspects of quality of life across the world. The chapters bring up case studies from different regions, showing how successful social marketing campaigns have been instrumental in addressing public health challenges, discrimination and exclusion, violence, and inequity; and in changing public perceptions in different countries and through public and nonprofit organizations, but also through businesses. Thus, this book approaches social marketing from a quality-of-life (QOL) marketing philosophy, taking an international perspective. It includes 26 case studies discussing how social marketing campaigns were developed and implemented in specific cases related to disease prevention and risk behavior, safe and healthy lifestyles, and inclusion and interpersonal relationships. It also covers social marketing campaigns related to COVID-19 in various countries.  The book is both comprehensive and provides in-depth understanding of every case, and is useful for research, policy making, development communication and social marketing. Graduate students, researchers, practitioners, and social marketers alike will find this book interesting.
