Investigative journalism has long been the cornerstone of a functioning democracy, serving to expose wrongdoing, hold power to account, and instigate change. Through tireless effort, determination, and often at significant personal risk, investigative journalists have uncovered some of the most pressing issues facing societies around the globe. Here are ten of the most impactful investigative journalism projects of all time, detailing their revelations and the changes they spurred.

1. Watergate Scandal

Perhaps the most famous investigation in journalistic history, Bob Woodward and Carl Bernstein of The Washington Post unearthed the Watergate scandal. Their reporting on the break-in at the Democratic National Committee headquarters in 1972 and subsequent cover-up by the Nixon administration led to President Nixon's resignation. This investigation underscored the role of the press in uncovering governmental malfeasance and led to sweeping reforms in campaign financing and greater transparency in government.

2. Pentagon Papers

In 1971, The New York Times began publishing the Pentagon Papers, a top-secret Department of Defense study of U.S. political and military involvement in Vietnam from 1945 to 1967. Exposed by Daniel Ellsberg, these documents revealed that successive U.S. administrations had misled the public about the Vietnam War's scale and prospects. The publication of the Pentagon Papers significantly eroded public support for the war and heightened skepticism toward government officials.

3. Spotlight on Clergy Abuse

The Boston Globe's Spotlight team unveiled the widespread sexual abuse of children by Roman Catholic priests in the Boston area in 2002. Their investigation, which detailed efforts by the church hierarchy to cover up the abuse, led to similar revelations worldwide, prompting major settlements and reforms within the Catholic Church regarding how such allegations are handled.

4. Panama Papers

In 2016, the International Consortium of Investigative Journalists (ICIJ) released the Panama Papers, a collection of 11.5 million leaked documents that exposed the offshore banking activities of more than 214,000 entities. The revelation implicated numerous global leaders, politicians, and celebrities in potential tax evasion and money laundering. The fallout led to resignations, official inquiries, and a push towards greater financial transparency worldwide.

5. Cambridge Analytica Scandal

The Observer and The New York Times, in partnership with whistleblower Christopher Wylie, exposed in 2018 how the data analytics firm Cambridge Analytica had harvested the personal data of millions of Facebook users without consent. The firm used this information to target voters in the run-up to the 2016 U.S. presidential election and the Brexit referendum. This investigation has had profound implications for data privacy, leading to significant fines for Facebook and increased scrutiny of digital privacy practices globally.

6. The Fall of Enron

In 2001, reporters from The Wall Street Journal began publishing stories that questioned the financial practices of Enron, leading to the eventual bankruptcy of what was one of America's largest companies. The reporting unveiled systemic accounting fraud and led to significant changes in U.S. securities laws, including the Sarbanes-Oxley Act, aimed at protecting investors from corporate abuses.

7. Tobacco Industry Exposé

In the 1990s, investigative journalists, most notably from The Wall Street Journal and ABC News, exposed how tobacco companies had known about the dangers of smoking for decades but had deliberately downplayed the risks. These revelations contributed to major lawsuits against tobacco companies and stringent regulations on tobacco advertising and labeling.

8. Rana Plaza Collapse Reporting

Following the collapse of the Rana Plaza garment factory in Bangladesh in 2013, which killed over 1,100 workers, journalists from around the world focused on the unsafe working conditions and exploitation in the global textile industry. Their investigations led to international pressure on clothing brands and retailers to improve labor practices and support safer working environments.

9. Operation Car Wash (Lava Jato)

Launched in 2014, Operation Car Wash is an ongoing investigation by Brazilian federal police into money laundering and corruption that eventually implicated dozens of high-ranking officials and business executives across Latin America. The extensive reporting on these scandals by journalists has led to numerous arrests, trials, and the implementation of anti-corruption measures in several countries.

10. The NSA Files

In 2013, The Guardian and The Washington Post reported on a series of documents leaked by former NSA contractor Edward Snowden, revealing widespread surveillance programs by the United States' National Security Agency. The NSA Files shed light on the extent of government spying on both foreign nationals and Americans, sparking a global debate on privacy, security, and the balance between them. These revelations led to policy changes in the U.S. and abroad, aiming to curb mass surveillance and protect citizens' privacy.
