Only some conflicts receive extensive worldwide coverage, however. Among recent wars, the Kosovo War received a great deal of coverage, as did the Persian Gulf War. In contrast, the largest war in the last half of the 20th century, the Iran–Iraq War, received far less substantial coverage. This is typical for wars among less-developed countries, as audiences are less interested and the reports do little to increase sales and ratings. The lack of infrastructure makes reporting more difficult and expensive, and the conflicts are also far more dangerous for war correspondents.
