One of the most recent innovations in television programming was the transmission of a special program for tourists in 1973. Bulgarian Radio and Television decided to cooperate with the Committee for Tourism to promote a 1-½-hour program for foreign tourists on the Black Sea coast. The program, as envisioned in 1973, would consist of local news, presented on three different channels in Russian, English, and German respectively; local events; international news; tourist information; and advertisements. Future plans for Bulgarian television were outlined in the Sixth Five Year Plan (1971-75). Although color television programs in the 1970s were transmitted to Bulgaria from Moscow, Bulgaria's own color television was to be transmitted in late 1973. Along these lines, Bulgaria planned to collaborate with Intervision--the Eastern European television network--in the promotion of color television. In 1972 plans were also being formulated for the construction of between 250 and 300 relay stations and additional television transmitters. PUBLISHING In 1939 there were 2,169 books and pamphlets published in 6.5 million copies, and in 1948 there were 2,322 books and pamphlets published in 19.9 million copies. By 1960 the number of book and pamphlet titles had risen to 3,369 in 30.2 million copies, and by 1971 the number of book and pamphlet titles reached 4,188 in 46.8 million copies. More recent studies of book and pamphlet publication conducted in 1969 and 1970 indicated that the overwhelming majority of books and pamphlets were written by Bulgarians. Of the 3,799 books published in 1970, there were 3,368 by Bulgarian authors. The foreign works during this year were predominantly in Russian, 131; French, sixty-five; English, sixty-five; and German, fifty-four. There were few books translated from Spanish and a sprinkling of translations from other lesser known languages. Of the translated works most were literary, followed by works dealing with the social sciences, the applied sciences, the arts, geography and history, the so-called hard sciences, philosophy, philology, and religion. A 1971 study illustrates the fact that--in terms of titles alone--books are more popular than pamphlets by a ratio of approximately three to one (see table 13). The greatest number of book titles in 1971 were in the areas of artistic and folkloric literature, technology and industry, and scientific and educational texts. The smallest number of book titles were in the areas of general handbooks, community affairs, and atheism and religion. The greatest number of pamphlet titles, on the other hand, were in juvenile literature, communist party literature, and science and education. The fewest pamphlet titles dealt with atheism and religion, Marxism-Leninism, languages, and labor and trade unions.
