A study of the "geography of Twitter" compares, among many other data sets, what it calls "Twitter versus mainstream news media." This part of Kalev Leetaru, Shaowen Wang, Guofeng Cao, Anand Padmanabhan and Eric Shook's study compared the geographic data from about five weeks' worth of tweets with locations from more than 3 million Google News articles during the same period.
"Does Twitter cover the same locations as the mainstream media, or do they discuss very different areas of the world?" they asked.
In one map, they compared "georeferenced Twitter Decahose (blue) and English Google News (red) geographic coverage" between Oct. 23, 2012 and Nov. 30, 2012.
"Areas that are blue have stronger Twitter representation," they write while, "while red areas are covered more closely by mainstream media, and white areas have an equal balance."
