"During this project, nearly 1800 individual articles and TV news shows were rated by at least three analysts with different political views (left, right and center). We had 20 analysts, each analyst having analyzed about 370 articles and about 17 TV shows. Each analyst rated approximately three articles from each of the over 100 news sources available for viewing on the Chart. As a result, we have nearly 7,000 individual ratings."
