This book investigates the meteoric rise of mobile webtoons - also known as webcomics - and the dynamic relationships between serialised content, artists, agencies, platforms and applications, as well as the global readership associated with them. It offers an engaging discussion of webtoons themselves, and what makes this new media form so compelling and attractive to millions upon millions of readers. Why have webtoons taken off, and how do users interact with them? Each of the case studies we explore raises interesting questions for both general readers and scholars of new media about how webtoons have become a modern form of popular culture. The book also addresses larger questions about East Asia's contributions to global popular culture and Asian society in general, as well as South Korea's rapid social and cultural transformation since the 1990s. This is a significant - and understudied - aspect of the new screen ecologies and their role in a new wave of media globalisation.
