In October 2014, Pew Research Center released a study, "Where News Audiences Fit on the Political Spectrum."
Pew described the study: "Where do Americans get their news about politics and government? And how does the media environment intersect with political polarization? A Pew Research Center study based on a representative online survey finds striking differences in news habits along the ideological spectrum."
The study created Audience Profiles which examined the ideological profiles of the audiences of news outlets. Viewers of the interactive study could also compare media habits by ideology: overall, consistently liberal, mostly liberal, mixed, mostly conservative, and consistently conservative.
