Investigative journalism is a form of journalism in which reporters deeply investigate a single topic of interest, such as serious crimes, racial injustice, 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".

Most investigative journalism has traditionally been conducted by newspapers, wire services, and freelance journalists. With the decline in income through advertising, many traditional news services have struggled to fund investigative journalism, due to it being very time-consuming and expensive. Journalistic investigations are increasingly carried out by news organizations working together, even internationally (as in the case of the Panama Papers and Paradise Papers), or by nonprofit outlets such as ProPublica, which rely on the support of the public and benefactors to fund their work.


University of Missouri journalism professor Steve Weinberg defined investigative journalism as: "Reporting, through one's own initiative and work product, matters of importance to readers, viewers, or listeners."[1] In many cases, the subjects of the reporting wish the matters under scrutiny to remain undisclosed. There are currently university departments for teaching investigative journalism. Conferences are conducted presenting peer-reviewed research into investigative journalism.[2]

British media theorist Hugo de Burgh (2000) states that: "An investigative journalist is a man or woman whose profession is to discover the truth and to identify lapses from it in whatever media may be available. The act of doing this generally is called investigative journalism and is distinct from apparently similar work done by police, lawyers, auditors, and regulatory bodies in that it is not limited as to target, not legally founded and closely connected to publicity."[3]


Early newspapers in British colonial America were often suppressed by the authorities for their investigative journalism. Examples include Publick Occurrences Both Forreign and Domestick and Benjamin Franklin's New England Courant. Journalists who reported on the doings of the British authorities would later contribute to revolutionary sentiment in the run-up to the American Revolution; one prominent example was the Boston Gazette, contributed to by Samuel Adams among others.[4]

American journalism textbooks point out that muckraking standards promoted by McClure's Magazine around 1902, "Have become integral to the character of modern investigative journalism."[5] Furthermore, the successes of the early muckrakers continued to inspire journalists.[6][7]

The outlook for investigative journalism in the United States was improved by the 1960s with the Freedom of Information Act and New York Times Co. v. Sullivan. The invention of the photocopier also offered an assistive tool to whistleblowers.[4]

The growth of media conglomerates in the U.S. since the 1980s has been accompanied by massive cuts in the budgets for investigative journalism. A 2002 study concluded "that investigative journalism has all but disappeared from the nation's commercial airwaves."[8] Non-commercial journalism has increasingly stepped-up to work on this growing need for in-depth investigations and reporting. One of the largest teams of investigative journalists is the Washington-based International Consortium of Investigative Journalists (ICIJ) launched in 1997 by the Center for Public Integrity[9] which includes 165 investigative reporters in over 65 countries[10] working collaboratively on crime, corruption, and abuse of power at a global level,[10] under Gerard Ryle as Director.[11] Working with major media outlets globally, they have exposed organised crime, international tobacco companies, private military cartels, asbestos companies, climate change lobbyists, details of Iraq and Afghanistan war contracts, and most recently the Panama Papers[10] and Paradise Papers.[12][13][14] The investigative Commons center opened in Berlin, Germany in 2021 and houses the European Center for Constitutional and Human Rights, Forensic Architecture, and Bellingcat.[15]


An investigative reporter may make use of one or more of these tools, among others, on a single story:
