Los muckrakers eran periodistas reformistas de la Era Progresista en los Estados Unidos (de 1890 a 1920) que denunciaron a las instituciones ya los líderes establecidos como corruptos . Por lo general, tenían una gran audiencia en revistas populares. El término moderno generalmente hace referencia al periodismo de investigación o al periodismo de vigilancia ; A los periodistas de investigación en los Estados Unidos a menudo se les llama informalmente "muckrakers".
Los muckrakers jugaron un papel muy visible durante la Era Progresista.  Revistas muckraking —en particular McClure's de la editorial SS McClure— se ocuparon de los monopolios corporativos y las maquinarias políticas , mientras intentaban aumentar la conciencia pública y la ira por la pobreza urbana , las condiciones laborales inseguras, la prostitución y el trabajo infantil .  La mayoría de los rastreadores de basura escribieron no ficción, pero las exposiciones de ficción a menudo también tuvieron un gran impacto, como las de Upton Sinclair . 
En el uso estadounidense contemporáneo, el término puede referirse a periodistas u otras personas que "investigan profundamente los hechos" o, cuando se usa de manera peyorativa, aquellos que buscan causar un escándalo.   El término es una referencia a un personaje del clásico Pilgrim's Progress de John Bunyan , "el hombre del rastrillo de estiércol", que rechazó la salvación para centrarse en la inmundicia. Se hizo popular después de que el presidente Theodore Roosevelt se refiriera al personaje en un discurso de 1906 ; Roosevelt reconoció que "los hombres con los rastrillos de estiércol son a menudo indispensables para el bienestar de la sociedad; pero solo si saben cuándo dejar de rastrillar el estiércol". 
While a literature of reform had already appeared by the mid-19th century, the kind of reporting that would come to be called "muckraking" began to appear around 1900. By the 1900s, magazines such as Collier's Weekly, Munsey's Magazine and McClure's Magazine were already in wide circulation and read avidly by the growing middle class. The January 1903 issue of McClure's is considered to be the official beginning of muckraking journalism, although the muckrakers would get their label later. Ida M. Tarbell ("The History of Standard Oil"), Lincoln Steffens ("The Shame of the Cities") and Ray Stannard Baker ("The Right to Work"), simultaneously published famous works in that single issue. Claude H. Wetmore and Lincoln Steffens' previous article "Tweed Days in St. Louis" in McClure's October 1902 issue was called the first muckraking article.
Changes in journalism prior to 1903
The muckrakers would become known for their investigative journalism, evolving from the eras of "personal journalism"—a term historians Emery and Emery used in The Press and America (6th ed.) to describe the 19th century newspapers that were steered by strong leaders with an editorial voice (p. 173)—and yellow journalism.
One of the biggest urban scandals of the post-Civil War era was the corruption and bribery case of Tammany boss William M. Tweed in 1871 that was uncovered by newspapers. In his first muckraking article "Tweed Days in St. Louis", Lincoln Steffens exposed the graft, a system of political corruption, that was ingrained in St. Louis. While some muckrakers had already worked for reform newspapers of the personal journalism variety, such as Steffens who was a reporter for the New York Evening Post under Edwin Lawrence Godkin, other muckrakers had worked for yellow journals before moving on to magazines around 1900, such as Charles Edward Russell who was a journalist and editor of Joseph Pulitzer's New York World. Publishers of yellow journals, such as Joseph Pulitzer and William Randolph Hearst, were more intent on increasing circulation through scandal, crime, entertainment and sensationalism.
Just as the muckrakers became well known for their crusades, journalists from the eras of "personal journalism" and "yellow journalism" had gained fame through their investigative articles, including articles that exposed wrongdoing. Note that in yellow journalism, the idea was to stir up the public with sensationalism, and thus sell more papers. If, in the process, a social wrong was exposed that the average man could get indignant about, that was fine, but it was not the intent to correct social wrongs as it was with true investigative journalists and muckrakers.
Julius Chambers of the New York Tribune could be considered to be the original muckraker. Chambers undertook a journalistic investigation of Bloomingdale Asylum in 1872, having himself committed with the help of some of his friends and his newspaper's city editor. His intent was to obtain information about alleged abuse of inmates. When articles and accounts of the experience were published in the Tribune, it led to the release of twelve patients who were not mentally ill, a reorganization of the staff and administration of the institution and, eventually, to a change in the lunacy laws. This later led to the publication of the book A Mad World and Its Inhabitants (1876). From this time onward, Chambers was frequently invited to speak on the rights of the mentally ill and the need for proper facilities for their accommodation, care and treatment.
Nellie Bly, another yellow journalist, used the undercover technique of investigation in reporting Ten Days in a Mad-House, her 1887 exposé on patient abuse at Bellevue Mental Hospital, first published as a series of articles in The World newspaper and then as a book. Nellie would go on to write more articles on corrupt politicians, sweat-shop working conditions and other societal injustices.
Other works that predate the muckrakers
- Helen Hunt Jackson (1831–1885) –A Century of Dishonor, U.S. policy regarding Native Americans.
- Henry Demarest Lloyd (1847–1903) – Wealth Against Commonwealth, exposed the corruption within the Standard Oil Company.
- Ida B. Wells (1862–1931) – an author of a series of articles concerning Jim Crow laws and the Chesapeake and Ohio Railroad in 1884, and co-owned the newspaper The Free Speech in Memphis in which she began an anti-lynching campaign.
- Ambrose Bierce (1842–1913(?)) – author of a long-running series of articles published from 1883 through 1896 in The Wasp and the San Francisco Examiner attacking the Big Four and the Central Pacific Railroad for political corruption.
- B. O. Flower (1858–1918) – author of articles in The Arena from 1889 through 1909 advocating for prison reform and prohibition of alcohol.
The muckrakers appeared at a moment when journalism was undergoing changes in style and practice. In response to yellow journalism, which had exaggerated facts, objective journalism, as exemplified by The New York Times under Adolph Ochs after 1896, turned away from sensationalism and reported facts with the intention of being impartial and a newspaper of record. The growth of wire services had also contributed to the spread of the objective reporting style. Muckraking publishers like Samuel S. McClure also emphasized factual reporting, but he also wanted what historian Michael Schudson had identified as one of the preferred qualities of journalism at the time, namely, the mixture of "reliability and sparkle" to interest a mass audience. In contrast with objective reporting, the journalists, whom Roosevelt dubbed "muckrakers", saw themselves primarily as reformers and were politically engaged. Journalists of the previous eras were not linked to a single political, populist movement as the muckrakers were associated with Progressive reforms. While the muckrakers continued the investigative exposures and sensational traditions of yellow journalism, they wrote to change society. Their work reached a mass audience as circulation figures of the magazines rose on account of visibility and public interest.
Magazines were the leading outlets for muckraking journalism. Samuel S. McClure and John Sanborn Phillips started McClure's Magazine in May 1893. McClure led the magazine industry by cutting the price of an issue to 15 cents, attracting advertisers, giving audiences illustrations and well-written content and then raising ad rates after increased sales, with Munsey's and Cosmopolitan following suit.
McClure sought out and hired talented writers, like the then unknown Ida M. Tarbell or the seasoned journalist and editor Lincoln Steffens. The magazine's pool of writers were associated with the muckraker movement, such as Ray Stannard Baker, Burton J. Hendrick, George Kennan (explorer), John Moody (financial analyst), Henry Reuterdahl, George Kibbe Turner, and Judson C. Welliver, and their names adorned the front covers. The other magazines associated with muckraking journalism were American Magazine (Lincoln Steffens), Arena (G. W. Galvin and John Moody), Collier's Weekly (Samuel Hopkins Adams, C.P. Connolly, L. R. Glavis, Will Irwin, J. M. Oskison, Upton Sinclair), Cosmopolitan (Josiah Flynt, Alfred Henry Lewis, Jack London, Charles P. Norcross, Charles Edward Russell), Everybody's Magazine (William Hard, Thomas William Lawson, Benjamin B. Lindsey, Frank Norris, David Graham Phillips, Charles Edward Russell, Upton Sinclair, Lincoln Steffens, Merrill A. Teague, Bessie and Marie Van Vorst), Hampton's (Rheta Childe Dorr, Benjamin B. Hampton, John L. Mathews, Charles Edward Russell, and Judson C. Welliver), The Independent (George Walbridge Perkins, Sr.), Outlook (William Hard), Pearson's Magazine (Alfred Henry Lewis, Charles Edward Russell), Twentieth Century (George French), and World's Work (C.M. Keys and Q.P.). Other titles of interest include Chatauquan, Dial, St. Nicholas. In addition, Theodore Roosevelt wrote for Scribner's Magazine after leaving office.
Origin of the term, Theodore Roosevelt
After President Theodore Roosevelt took office in 1901, he began to manage the press corps. To do so, he elevated his press secretary to cabinet status and initiated press conferences. The muckraking journalists who emerged around 1900, like Lincoln Steffens, were not as easy for Roosevelt to manage as the objective journalists, and the President gave Steffens access to the White House and interviews to steer stories his way.
Roosevelt used the press very effectively to promote discussion and support for his Square Deal policies among his base in the middle-class electorate. When journalists went after different topics, he complained about their wallowing in the mud. In a speech on April 14, 1906 on the occasion of dedicating the House of Representatives office building, he drew on a character from John Bunyan's 1678 classic, Pilgrim's Progress, saying:
...you may recall the description of the Man with the Muck-rake, the man who could look no way but downward with the muck-rake in his hands; who was offered a celestial crown for his muck-rake, but who would neither look up nor regard the crown he was offered, but continued to rake to himself the filth of the floor.
While cautioning about possible pitfalls of keeping one's attention ever trained downward, "on the muck", Roosevelt emphasized the social benefit of investigative muckraking reporting, saying:
There are, in the body politic, economic and social, many and grave evils, and there is urgent necessity for the sternest war upon them. There should be relentless exposure of and attack upon every evil man whether politician or business man, every evil practice, whether in politics, in business, or in social life. I hail as a benefactor every writer or speaker, every man who, on the platform, or in book, magazine, or newspaper, with merciless severity makes such attack, provided always that he in his turn remembers that the attack is of use only if it is absolutely truthful.— Theodore Roosevelt
Most of these journalists detested being called muckrakers. They felt betrayed that Roosevelt would describe them with such a term after they had helped him with his election. Muckraker David Graham Philips believed that the tag of muckraker brought about the end of the movement as it was easier to group and attack the journalists.
The term eventually came to be used in reference to investigative journalists who reported about and exposed such issues as crime, fraud, waste, public health and safety, graft, and illegal financial practices. A muckraker's reporting may span businesses and government.
Muckraking de principios del siglo XX
Ray Stannard Baker Lincoln Steffens Ida M Tarbell Upton Sinclair Will Irwin David Graham Phillips Jacob Riis Charles Edward Russell William English Walling Mark Sullivan with his secretary, Mabel Shea
Some of the key documents that came to define the work of the muckrakers were:
Ray Stannard Baker published "The Right to Work" in McClure's Magazine in 1903, about coal mine conditions, a coal strike, and the situation of non-striking workers (or scabs). Many of the non-striking workers had no special training or knowledge in mining, since they were simply farmers looking for work. His investigative work portrayed the dangerous conditions in which these people worked in the mines, and the dangers they faced from union members who did not want them to work.
Lincoln Steffens published "Tweed Days in St. Louis", in which he profiled corrupt leaders in St. Louis, in October 1902, in McClure's Magazine. The prominence of the article helped lawyer Joseph Folk to lead an investigation of the corrupt political ring in St. Louis.
Ida Tarbell published The Rise of the Standard Oil Company in 1902, providing insight into the manipulation of trusts. One trust they manipulated was with Christopher Dunn Co. She followed that work with The History of The Standard Oil Company: the Oil War of 1872, which appeared in McClure's Magazine in 1908. She condemned Rockefeller's immoral and ruthless business tactics and emphasized "our national life is on every side distinctly poorer, uglier, meaner, for the kind of influence he exercises." Her book generated enough public anger that it led to the splitting up of Standard Oil under the Sherman Anti Trust Act.
Upton Sinclair published The Jungle in 1906, which revealed conditions in the meat packing industry in the United States and was a major factor in the establishment of the Pure Food and Drug Act and Meat Inspection Act. Sinclair wrote the book with the intent of addressing unsafe working conditions in that industry, not food safety. Sinclair was not a professional journalist but his story was first serialized before being published in book form. Sinclair considered himself to be a muckraker.
"The Treason of the Senate: Aldrich, the Head of it All", by David Graham Phillips, published as a series of articles in Cosmopolitan magazine in February 1906, described corruption in the U.S. Senate. This work was a keystone in the creation of the Seventeenth Amendment which established the election of Senators through popular vote.
The Great American Fraud (1905) by Samuel Hopkins Adams revealed fraudulent claims and endorsements of patent medicines in America. This article shed light on the many false claims that pharmaceutical companies and other manufacturers would make as to the potency of their medicines, drugs and tonics. This exposure contributed heavily to the creation of the Pure Food and Drug Act alongside Upton Sinclair's work. Using the example of Peruna in his article, Adams described how this tonic, which was made of seven compound drugs and alcohol, did not have "any great potency". Manufacturers sold it at an obscene price and hence made immense profits. His work forced a crackdown on a number of other patents and fraudulent schemes of medicinal companies.
Many other works by muckrakers brought to light a variety of issues in America during the Progressive era. These writers focused on a wide range of issues including the monopoly of Standard Oil; cattle processing and meat packing; patent medicines; child labor; and wages, labor, and working conditions in industry and agriculture. In a number of instances, the revelations of muckraking journalists led to public outcry, governmental and legal investigations, and, in some cases, legislation was enacted to address the issues the writers identified, such as harmful social conditions; pollution; food and product safety standards; sexual harassment; unfair labor practices; fraud; and other matters. The work of the muckrakers in the early years, and those today, span a wide array of legal, social, ethical and public policy concerns.

The influence of the muckrakers began to fade during the more conservative presidency of William Howard Taft. Corporations and political leaders were also more successful in silencing these journalists as advertiser boycotts forced some magazines to go bankrupt. Through their exposés, the nation was changed by reforms in cities, business, politics, and more. Monopolies such as Standard Oil were broken up and political machines fell apart; the problems uncovered by muckrakers were resolved and thus the muckrakers of that era were needed no longer.
According to Fred J. Cook, the muckrakers' journalism resulted in litigation or legislation that had a lasting impact, such as the end of Standard Oil's monopoly over the oil industry, the establishment of the Pure Food and Drug Act of 1906, the creation of the first child labor laws in the United States around 1916. Their reports exposed bribery and corruption at the city and state level, as well as in Congress, that led to reforms and changes in election results.
"The effect on the soul of the nation was profound. It can hardly be considered an accident that the heyday of the muckrakers coincided with one of America's most yeasty and vigorous periods of ferment. The people of the country were aroused by the corruptions and wrongs of the age – and it was the muckrakers who informed and aroused them. The results showed in the great wave of progressivism and reform cresting in the remarkable spate of legislation that marked the first administration of Woodrow Wilson from 1913 to 1917. For this, the muckrakers had paved the way."
Other changes that resulted from muckraker articles include the reorganization of the U.S. Navy (after Henry Reuterdahl published a controversial article in McClure's). Muckraking investigations were used to change the way senators were elected by the Seventeenth Amendment to the U.S. Constitution and led to government agencies to take on watchdog functions.
Some today use "investigative journalism" as a synonym for muckraking. Carey McWilliams, editor of the Nation, assumed in 1970 that investigative journalism, and reform journalism, or muckraking, were the same type of journalism. Journalism textbooks point out that McClure's muckraking standards "Have become integral to the character of modern investigative journalism." Furthermore, the successes of the early muckrakers have continued to inspire journalists. Moreover, muckraking has become an integral part of journalism in American history. Bob Woodward and Carl Bernstein exposed the workings of the Nixon Administration in Watergate, which led to Nixon's resignation. More recently, Edward Snowden disclosed the activities of governmental spying, albeit illegally, which gave the public knowledge of the extent of the infringements on their privacy.
