News values are the professional norms of journalism. Commonly, news content should contain the "Five Ws" (who, what, when, where, why, and also how) of an event. There should be no questions remaining. Newspapers normally place hard news stories on the first pages, so the most important information is at the beginning.
Busy readers can read as little or as much as they desire. Local stations and networks with a set format must take news stories and break them down into the most important aspects due to time constraints.
