A correspondent or on-the-scene reporter is usually a journalist or commentator for a magazine, or an agent who contributes reports to a newspaper, or radio or television news, or another type of company, from a remote, often distant, location.
The term "correspondent" refers to the original practice of filing news reports via postal letter.
The largest networks of correspondents belong to ARD (Germany) and BBC (UK).
In Britain, the term 'correspondent' usually refers to someone with a specific specialist area, such as health correspondent.
The producers of the show schedule time with the correspondent, who then appears "live" to file a report and chat with the hosts.
