A report written in 1959 by Mark May, a Yale University professor and expert on psychological warfare, detailed the extensive operations by the United States Information Service (USIS) in Japan after the end of World War II. The report was recently uncovered in the National Archives in Washington by Kenneth Osgood, an assistant professor of history at Florida Atlantic University. The report reveals that 23 of 50 USIS-sponsored programs were not publicly identified as U.S. funded projects.
