Every week the Project for Excellence in Journalism produced the News Coverage Index, a report identifying the main subjects covered by the U.S. mainstream media and analyses the percentage of the available space, or news hole, devoted to each major subject. It was used to analyze media coverage of events such as Occupy Wall Street.
^Brian Stelter (November 20, 2011). "Protest Puts Coverage in Spotlight". The New York Times. Retrieved November 21, 2011. An analysis by the Pew Research Center’s Project for Excellence in Journalism indicates that the movement occupied 10 percent of its sample of national news coverage in the week beginning Oct. 9, then steadily represented about 5 percent through early November. Coverage dipped markedly, to just 1 percent of the national news hole, in the week beginning Nov. 6, supporting Ms. Shepard’s assertion that it had “died down” before the early morning eviction in New York last Tuesday. It has since rebounded strongly.
