Investigative journalism is a form of journalism in which reporters deeply investigate a single topic of interest, such as serious crimes, political corruption, or corporate wrongdoing. An investigative journalist may spend months or years researching and preparing a report. Practitioners sometimes use the terms "watchdog reporting" or "accountability reporting".
Journalism refers to the production and distribution of reports on recent events. The word journalism applies to the occupation (professional or not), the methods of gathering information and organising literary styles. Journalistic mediums include print, television, radio, Internet and in the past: newsreels.
