Digitalization is one of the defining phenomena of our age, fundamentally transforming communication, social structures, and human interaction. Communication has always been the foundation of social life; it has developed hand in hand with technology throughout history, from the most primitive forms of signaling to the digital devices we carry in our pockets today. Digitalization is not merely a technological advancement; it has spearheaded new transformations at the individual, cultural, and societal levels. These transformations are adding new dimensions to the ways in which people, societies, and organizations communicate. Our book, titled “Digital Communication: Technology and Interaction,” consists of eight chapters that aim to offer a broad perspective through an interdisciplinary approach.

The chapter by Zeynep Ekmekçi, titled “Theoretical Approaches to Digital Media Literacy: Critical, Social, and Cognitive Perspectives,” discusses digital media literacy within various theoretical frameworks and analyzes the concept through epistemological, critical, structuralist/post-structuralist, and cultural dimensions. Yılmaz Alışkan contributes the chapter “Inequality and Exploitation in the Digital Media Field: A General Overview of the Concepts of Digital Capitalism, Surveillance Capitalism, the Digital Divide, and Platform Capitalism” which analyzes the contemporary forms of exploitation in the digital world through these key conceptual frameworks.
