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.
