From the perspective of the development of the discipline, it seems that the journalism and communication in China has been in a "nervous anxiety" of the legitimacy of the discipline since its establishment, and it often launches various defenses for the proposition of "learning without learning". Since the first decade of the 21st century, digital media technology represented by the Internet has made rapid progress, which has brought a strong impact on the news production practice and information dissemination ecology based on traditional mass media such as newspapers, periodicals, radio and television, and has intensified the reflection and reconstruction of existing concepts, theoretical paradigms, research methods and professional boundaries of the discipline. Therefore, this book first Outlines the news communication and practice under the background of the new era, and then carries out in-depth research on its theoretical basis, communicators and their audiences, humanity, business and public opinion control, aiming to provide reference for the development of relevant practical activities and research work.
