In journalism and public relations, a news embargo or press embargo is a request by a source that the information or news provided by that source not be published until a certain date or certain conditions have been met. The understanding is that if the embargo is broken by reporting before then, the source will retaliate by restricting access to further information by that journalist or his publication, giving them a long-term disadvantage relative to more cooperative outlets. They are often used by businesses making a product announcement, by medical journals, and by government officials announcing policy initiatives; the media is given advance knowledge of details being held secret so that reports can be prepared to coincide with the announcement date and yet still meet press time. In theory, press embargoes reduce inaccuracy in the reporting of breaking stories by reducing the incentive for journalists to cut corners in hopes of "scooping" the competition.
