Final answer:
The term 'communication channel' is used to describe the established pathways for information exchange within organizations, which are part of the mass media. Mass media include traditional forms like newspapers and TV, but with new technology, media reach has expanded, increasing access to information and changing how media operates.
Step-by-step explanation:
A communication channel refers to the major, well-established channels for information exchange within an organization. These channels are a part of the mass media that includes different formats such as newspapers, magazines, television, and radio, designed to reach large audiences and deliver a variety of content, including news, entertainment, and educational material. The role of the media is multifaceted as it serves to inform the public, scrutinize government actions, set socio-political agendas, and entertain. With technological evolution, new media forms such as internet streaming and social media platforms have also become significant, diluting the traditional gatekeeping role and allowing more direct and diverse information dissemination.
Mass media play a vital role as a common carrier in providing a line of communication between the government and the people, with news media often acting as a linkage institution. Despite advancements and increases in personal communication technology, mass media remain a consistent and significant source of information. However, the recent surge in unprofessional journalism and social media platforms presents challenges like misinformation and sensationalism. These challenges highlight the critical balance media must maintain between being a trusted source of information and the competition for audience and advertising revenue.
