As the system has evolved, the broad outlines of propaganda have been dictated from the Politburo, the party's chief policymaking unit. From there policy is transmitted to the Agitation and Propaganda Department (Agitprop), which is a major operational unit of the Central Committee. Agitprop, in turn, is responsible for the transmission of guidelines down to the lowest levels of party organization. Simultaneously, the same dictates are transmitted throughout all cultural institutions by the Ministry of Information and Communications. Under this ministry's jurisdiction are the arts, the film industry, radiobroadcasting, television, book and pamphlet publishing, printing, all cultural or educational institutions, and all so-called independent artists. Still a third channel for the transmission of the original propaganda are the mass organizations that function in the propaganda field under direction of either Agitprop or the Ministry of Information and Communications (see ch. 9). The administrative center for all media is Sofia, the capital. Eight daily newspapers are published in Sofia and distributed throughout the country; there are also seventeen major publishing houses in Sofia. The National Film Board, which oversees all aspects of film production, is in Sofia, as is Radio Sofia, which is the radio station for the entire country. The Cyril and Methodius Library--also known as the Bulgarian National Library--is within the confines of the city, as are the Union of Bulgarian Writers; the Union of Bulgarian Artists; and the Union of Composers, Musicologists, and Performing Musicians (see ch. 7). The exportation of propaganda is under the auspices of the Sofia Press Agency. This agency was founded in 1967 with the express purpose of disseminating Bulgarian propaganda to other countries. Its three major tasks are to publicize Bulgaria's achievements and successes actively to the world; to attempt to counter anti-Bulgarian propaganda; and to provide the various communist parties of the world with rationale in their struggles against capitalism. In 1972 the Sofia Press Agency was in the process of negotiating agreements with the BTA and the Committee for Television and Radio. Agreements had already been established with book publishers, photographic artists, and the film industry. In early 1972 over 500 people--the majority of whom were editors and translators--were working for the Sofia Press Agency, and contracts had been signed with approximately 120 foreign countries. Nine magazines, translated into eleven languages, had been published each year in 2.5 million copies. A dual language newspaper has been published each year in 500,000 copies, and 400 books had appeared in approximately 4 million copies. Some 15,000 articles had been written, 30,000 photographs taken, and dozens of television motion pictures and documentaries had been filmed. News Agency
