In 1942, in the midst of World War II, the United States government contracted with the Crosley Broadcasting Corporation to build a radio station capable of broadcasting its message around the world. The Crosley Broadcasting Corporation chose to build the installation on six hundred acres of land in Union Township, Ohio, approximately twenty-five miles north of Cincinnati, Ohio. The site became known as Bethany Station. The program broadcast from the site became known as Voice of America.
