Categories Awards are made in categories relating to journalism, arts, letters and fiction. Reports and photographs by United States–based newspapers, magazines and news organizations (including news websites) that "[publish] regularly" are eligible for the journalism prize. Beginning in 2007, "an assortment of online elements will be permitted in all journalism categories except for the competition's two photography categories, which will continue to restrict entries to still images." In December 2008, it was announced that for the first time content published in online-only news sources would be considered. Although certain winners with magazine affiliations (most notably Moneta Sleet Jr.) were allowed to enter the competition due to eligible partnerships or concurrent publication of their work in newspapers, the Pulitzer Prize Advisory Board and the Pulitzer Prize Board historically resisted the admission of magazines into the competition, resulting in the formation of the National Magazine Awards at the Columbia Journalism School in 1966. In 2015, magazines were allowed to enter for the first time in two categories (Investigative Reporting and Feature Writing). By 2016, this provision had expanded to three additional categories (International Reporting, Criticism and Editorial Cartooning).

In October 2016, magazine eligibility was extended to all journalism categories. Hitherto confined to the local reporting of breaking news, the Breaking News Reporting category was expanded to encompass all domestic breaking news events in 2017.
