There has been no systematic study of the effectiveness of broadcasting by the Church of Jesus Christ of Latter-day Saints since the advent of TV and the nation-wide telecasting of the Annual and Semi-Annual General Conferences of the Church each April and October. In addition to determining effectiveness, there is a need to discover to what degree people watch or listen to religious programming in general, and what types of religious programs they wouldm most like to have available.The Northern States Mission of the Church, including all or part of Illinois, Wisconsin, Iowa, and Indiana, was seleceted as a represntative area for the purpose of the survey. Data was obtained by means of a questionnaire utilized in door-to-door proselyting by the L.D.S. missionaries in the mission area. The survey was conducted over a period of seven months, from October, 1963, through April, 1964, thus encompassing the broadcasting of two church General Conferences.
