A reporter, newscaster, or correspondent was a type of journalist who wrote and/or discussed current events as part of a news publication or broadcast. Most news reporters worked for a news organization. Their work was accessible via newspaper, television, and other forms of media.

In 1947, during the Roswell Incident, someone from Roswell had initially informed the press that a flying saucer had crashed, but was later "convinced" by USAAF personnel to issue a retraction that it had been just a weather balloon.

Sisko later that year promised Nog he wasn't coming with him to Ferenginar as a reporter, though this later turned out to be not entirely true.
