The Institute for Economics and Peace and Media Tenor have released "Measuring Peace in the Media":
"The results show broad inconsistencies across geographies and networks, with US broadcasters much more focused on violence and conflict than their European and Middle Eastern counterparts. Al Jazeera was found to be the network providing the most balanced coverage on Afghanistan. BBC World led the way when it came to breadth of coverage. ...
Positive-peace stories make up just 1.6% of the total number of stories examined in the study.
CNN International, BBC World and Al Jazeera English all had similar number of reports on the topics that received the most total coverage – warfare, elections, crime and international politics. However, Al Jazeera had the greatest breadth of coverage, including more coverage on topics which related progress in creating peace."
