A correspondent or on-the-scene reporter is a journalist or commentator who contributes reports to a newspaper, or radio or television news, from a remote, often distant, location. A foreign correspondent is stationed in a foreign country. The term correspondent refers to the original practice of filing news reports via postal letter.
In Britain the term 'correspondent' usually refers to someone with a specific specialist area, such as health correspondent. A 'reporter' is usually someone without such expertise who is allocated stories by the newsdesk on any story in the news.
A war correspondent covers stories first-hand from a war zone. It is perhaps the most dangerous form of journalism.
A recent cost-saving measure is for local tv news to dispense with out-of-town reporters and replace them with syndicated correspondents, usually supplied by a centralized news reporting agency. The producers of the show schedule time with the correspondent, who then appears "live" to file a report and chat with the hosts. The reporter will go do a number of similar reports for other stations. Many viewers may be unaware that the reporter does not work directly for the news show. This is also a popular way to report the weather. For example, AccuWeather doesn't just supply data, they also supply on-air meteorologists from television studios at their headquarters.
