As its name implies, “news” typically connotes the presentation of new information.
The newness of news gives it an uncertain quality which distinguishes it from the more careful investigations of history or other scholarly disciplines.
Whereas historians tend to view events as causally related manifestations of underlying processes, news stories tend to describe events in isolation, and to exclude discussion of the relationships between them.
News conspicuously describes the world in the present or immediate past, even when the impost important aspects of a news story have occurred long in the past—or are expected to occur in the future. To make the news, an ongoing process must have some “peg”, an event in time which anchors it to the present moment.
Relatedly, news often addresses aspects of reality which seem unusual, deviant, or out of the ordinary.
