"Who does public communication serve?". In a simple and objective way, we could answer what seems obvious: it serves society as a whole, since public communication is communication that contributes to matters of public interest. Despite being clear and straightforward, the answer doesn't seem to address the complexity of the issue. The debate about the construction of a concept of public communication, as well as the understanding of its practice, has given rise to national and international academic research since the end of the 20th century. Interpreted generically, the word Communication legitimizes all kinds of discourse and serves different interests, including government interests. In this sense, the failure (or lack) of consensus on what is and isn't public communication seems to be an advantage for private organizations (such as companies and political parties) and, above all, for the public administration. The aim is for information to be disseminated by the media as matters of public interest. Even better if these "issues" are classified as journalistic news and disseminated by the press, whether commercial or public. That's what this article is about.
