Introduction

Communication plays a fundamental role in the ways we communicate ideas with one another, influence behavior and establish identity within individuals, organizations and societies. The discipline of communication is currently Global Communication, Media Studies, Digital Communication, Organizational Communication, Political Communication, and Intercultural Communication, among others. In this day and age, our world is ever more connected through advances in technology, the rise to prominence of social media, and journalism’s digital footprints that are changing how information is shared, interpreted, and retrieved, all while breaking down barriers around accessibility. In addition, present-day communication is presenting issues of misinformation, ethical communication, cultural representation, and media’s influence on public perception that now take on a new meaning.

Background Context

Communications research brings together theory and practice, including the study of the construction, dissemination, and reception of messages in an ever-changing communications environment.Communication is examined by a communications scholar to understand its role in shaping social attitudes, political practices, cultural exchange, and organizational outcomes. Established theories of communication have always been connecting with real-time issues globally, such as when considering digital literacy, online harm, crisis communications, and the ethical implications of AI within media organizations. Overall, communications research helps to engage academics, but also helps create pathways for policy makers, businesses, educators, and communities to act with and within the ever-changing media landscape.
