So how did we get to this point? To find out, Stacker compiled a list of important moments in journalism history between 1921 and 2020. It looked at information from think tanks, such as the Pew Research Center and Brookings Institution; universities, including the University of Virginia, University of North Carolina at Chapel Hill, and the University of Kansas; and journalism-focused publications, like the Columbia Journalism Review. And of course, it also looked at archival articles from major media, like The New York Times and The Washington Post.
