In journalism and public relations, a news embargo or press embargo is a request or requirement by a source that the information or news provided by that source not be published until a certain date or certain conditions have been met. 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 by writing up information quickly in hopes of "scooping" the competition. A similar concept are review embargoes in video games, computer hardware and films; in these, reviewers are given early access to content or products in exchange for keeping review results secret until the embargo is lifted, preventing inaccuracies in reviews or lackluster sales at launch or to allow any flaws, bugs or other inconsistencies discovered by reviewers to be fixed before launch, preventing problems after launch. 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 their publication, giving them a long-term disadvantage relative to more cooperative outlets. Embargoes are usually arranged in advance as "gentlemen's agreements." However, sometimes publicists will send embargoed press releases to newsrooms unsolicited in hopes that they will respect the embargo date without having first agreed to do so—the phrase "For Immediate Release" often found at the top of press releases indicates that the information in the release is not embargoed. News organizations sometimes break embargoes and report information before the embargo expires, either accidentally (due to miscommunication in the newsroom) or intentionally (to get the jump on their competitors). Breaking an embargo is typically considered a serious breach of trust and can result in the source barring the offending news outlet from receiving advance information for a long period of time. News embargoes are one of several ways a source can influence media presentation of the information they provide; others include providing information "on background" or "not for attribution," limiting or providing "access," or even direct government or market intervention against the reporters or media company.
