Gate-keeping

A filtering process, which determines which of the countless possible stories actually get published. Useful gate-keeping ensures that fluffy and exciting stories that are easy to write don't crowd out the dry but important stories that require extensive research.

Extreme gatekeepers are censors, preventing the publication of information that could be unflattering to powerful people (such as the owners of a news organization, or the dominant political party).  For instance, in order to keep the U.S. leadership from looking weak during the build-up to World War II, reporters kept silent about the fact that FDR used a wheelchair.

In a more moderate form, gate-keepers are the editors who keep the news media from choking on stories about lost puppies, yo-yo tournaments, and celebrity sex scandals; who agree not to publish the names of certain crime victims (including children and the targets of sexual assault), even though those names may be available in public documents; and who ensure that someone covers the routine stories about zoning law changes and city council meetings, whether politicians who campaigned on certain problems actually kept them, etc.
