Studies have shown that what the media decides to expose correlates with their views on things such as politics, economy and culture. Aside from bias, other critics of the news media claim that news in the United States has become a form of entertainment. Instead of providing the public with the information they need, journalists instead strive to fill the publics' appetite for shocking and sensational headlines. Countries that tend to have more political power are more likely to receive media exposure. Financial resources, technologies, foreign trade and money spent on the military can be some of the main factors that explain coverage inequality.
