Mass communication is a field of study that involves the process of creating, sending, receiving, and analyzing messages to a large audience through various forms of media, such as television, radio, newspapers, magazines, social media, and the internet. It explores how information is transmitted and consumed by the public, and how media organizations shape public opinion and influence society. Mass communication also examines the impact of technology on communication, the role of media in shaping cultural norms and values, and the ethical considerations of media production and consumption. Researchers in this field often study media effects, media literacy, media ethics, media ownership, and media sociology.
