A reporter or correspondent was a type of journalist who found and told others about events. Most news reporters worked for a news organization, and their work could be disseminated via newspaper, television, or other media.
Jack London was a reporter in the 19th century. He later described himself as having been a "newsie" (an informal name for reporter) to Data when he introduced himself to the android. (TNG: "Time's Arrow")
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. Captain Wainwright considered this necessary to prevent reporters from "snooping around". (DS9: "Little Green Men")
Jake Sisko became an official correspondent for the Federation News Service in late 2373. He considered it as part of his reporter job to stay on Deep Space 9 during the Dominion occupation of the station. (DS9: "Call to Arms") During this occupation, he claimed that as a reporter people talked to him and that he had ways of getting information out. (DS9: "Sons and Daughters", "Favor the Bold")
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. Onboard the USS Valiant, Tim Watters appealed to Jake that as a reporter it was his job to watch events unfold and write about them, not interfere in them. (DS9: "Valiant")
