Overview
Media (媒體, media) refers to the means or systems for conveying information, messages, and content. It is classified into print media (newspapers, magazines), electronic media (radio, television), and digital media (internet, social media). In modern society, media goes beyond being a simple delivery tool, playing various roles such as shaping public opinion, spreading culture, and exercising political influence. The development of media has fundamentally transformed human communication methods and social structures.

Definition and Classification of Media
Media is broadly divided into traditional media and new media. Traditional media includes print media (newspapers, magazines, books) and broadcast media (radio, TV), characterized by one-way information delivery. New media refers to internet, social media, and mobile apps based on digital technology, featuring interactivity and real-time capabilities. Media is also classified by sensory characteristics into visual media (photography, video), auditory media (music, podcasts), and multi-sensory media (virtual reality, augmented reality).
Historical Development of Media
The history of media begins with oral culture. Humanity conveyed information through language, but due to the limitations of recording, writing was invented. Gutenberg's printing press in the 15th century sparked a media revolution, enabling the popularization of knowledge. The telegraph and telephone in the 19th century, and radio and television in the 20th century, opened the era of electronic media. The spread of the internet since the 1990s fully ushered in the digital media era. The emergence of social media in the 2000s promoted user-generated content (UGC) and personalized media consumption.
Social Functions of Media
Media performs various functions, including information provision, public opinion formation, education, entertainment, cultural transmission, and surveillance and criticism. Particularly in the political sphere, media serves as a public sphere and acts as a crucial intermediary in democratic processes. However, the commercialization and concentration of media ownership can hinder diversity of information and risk reinforcing specific ideologies. Media also contributes to constructing social reality; according to framing theory, how media reports on specific events can alter public perception.
Media Effects Theories
Research on media effects has developed various theories. The 'limited effects model' from the 1940s argued that media does not directly influence audiences but is mediated by individual attitudes and social relationships. In contrast, the 'agenda-setting theory' from the 1970s posits that media determines what the public considers important by emphasizing certain issues. The 'spiral of silence theory' explains how media reinforces majority opinions and suppresses minority views. Recently, 'framing theory' and 'priming effects' have gained attention, studying how media language and images influence audience interpretation.
Media and Cultural Industry
Media forms a core pillar of the cultural industry. Film, music, broadcasting, publishing, and games are distributed through media, shaping the global cultural content market. Platforms like Netflix, YouTube, and Spotify have innovated traditional media distribution methods, and the spread of OTT (Over-The-Top) services has changed viewing patterns. Media is also closely linked to the advertising industry, with digital advertising enhancing efficiency through targeting and data analysis.
Media Ethics and Regulation
The freedom and responsibility of media are always subjects of debate. Freedom of the press is a fundamental principle of democracy, but issues such as misinformation, hate speech, and privacy violations can arise. Countries have established legal frameworks for media regulation; in South Korea, the Korea Communications Commission and the Press Arbitration Commission perform related roles. The proliferation of digital media has raised new ethical challenges, including fake news, algorithmic bias, and data monopolies.
Recent Trends
As of 2024-2025, the media environment is characterized by the rapid integration of generative AI. AI is used across content production, including news writing, video creation, and music composition, sparking active ethical discussions in journalism and creative fields. Social media platforms face regulatory pressure regarding algorithmic transparency and user data protection, with laws such as the EU's Digital Services Act (DSA) being implemented. Personalized media like podcasts and newsletters continue to grow, and immersive journalism experiments using virtual reality (VR) and augmented reality (AR) are increasing. Notably, the role of media and misinformation issues emerged as key topics during the 2024 U.S. presidential election and the 2025 South Korean political calendar.
