Propaganda is the transmission of information to affect public opinion, such as facts, arguments, rumors, half-truths, or falsehoods. It can be accomplished through various media, including but not limited to newspapers, magazines, radio, television, online news sites, and social media. In the United States, government propaganda has been used by both parties to advance their positions during political campaigns. After elections, some believe that politicians use propaganda to influence the public opinion more effectively than with votes. Some government agencies have also used propaganda as a tool for influencing public opinion. The Central Intelligence Agency (CIA) has done so via its Radio Free Europe/Radio Liberty service since the early 1950s. The Federal Bureau of Investigation (FBI) has also used propaganda to influence public opinion. The U.S. Department of State has employed journalists worldwide to provide information about America's economic interests and policies. They have also sponsored events like the Conference on World Affairs to promote American values abroad. During the Cold War, the term was often used to describe propaganda produced by the Soviet Union. Today, it is used to describe similar material produced by other countries as well.
