The Routledge Companion to Transnational Journalism History offers a comprehensive account of the development of journalism throughout history, focusing on the interactions between agents, ideas, innovations, norms, and social and cultural practices that extend beyond national boundaries. Transcending traditional nation-specific approaches to journalism history, this cutting-edge collection considers the structures that have facilitated the transfer of journalistic innovations between nations and allowed for transnational reporting. These structures include legal frameworks, professional ethics, technologies, audiences, and media events. Across 35 chapters, a diverse range of international contributors unpack the concept of transnational journalism history via themes including transnational networks; material culture; genres and practices; and the transfer of journalistic norms, practices, and conventions. This is a key resource for scholars and advanced students of journalism history and cross-cultural journalism.
