This document discusses the role and definition of journalism. It makes three key points:
1. Journalism aims to disseminate and analyze news and information to serve the public. It is based on principles of truth, disclosure, and editorial independence.
2. Journalistic mediums are diverse and include print, broadcast, online, and digital formats like newspapers, television, websites and smartphones.
3. In modern societies, news media is the main source of public information and opinion, though citizen journalism is increasingly playing a role through platforms like YouTube. Access to independent media sources helps citizens participate in the political process.
