Public communication happens when individuals and groups engage in dialogue in the public sphere in order to deliver a message to a specific audience. Public speaking events, newspaper editorials and billboard advertisements are a few forms of public communication.
Entertainment, education and politics are all potential subjects of public communication. Universities often use this phrase to refer to a specific field of academic study that focuses on the strategic use of mass communication technologies to reach an audience. Laws typically regulate public communication differently than private communication. Other examples of public communication include political television ads and events where face-to-face interaction occurs, such as town hall meetings and academic conferences.
