Since the late 19th century, American journalists have used their craft to call government and corporations to account for wrongdoing, secret practices, and even corruption, often sparking public outcry and reform. In the latest Brookings Essay, Robert Kaiser, former managing editor of The Washington Post, examines the digital revolution that has forever changed American journalism, and not for the better.

It also focuses on print journalism, though many great episodes of the form have appeared on television. As well, this investigative journalism is but one facet of the vital profession that reports the news.
