Through several international broadcasting operations, the US disseminates American cultural information, official positions on international affairs, and daily summaries of international news. These operations fall under the International Broadcasting Bureau, the successor of the United States Information Agency, established in 1953. IBB's operations include Voice of America, Radio Liberty, Alhurra and other programs. They broadcast mainly to countries where the United States finds that information about international events is limited, either due to poor infrastructure or government censorship. The Smith-Mundt Act prohibits the Voice of America from disseminating information to US citizens that were produced specifically for a foreign audience.
