The purpose of this thesis is to assess the potential for the educational use of cable television, note representative experiments with the medium, and project future trends. A single cable television system in Marin County, California was chosen as a focus for these observations. Literature review and personal interview are the primary techniques of this analysis. The national regulatory background to and educational experience with the cable television medium are documented. A history of cable television in Marin County is constructed; and the experience of Marin educators with television generally and cable television specifically are recorded. The major findings indicate that there will not be much use of cable television by Marin educators in the near future. The level of interest in the subject among educators is not great, even though Marin County would appear to be hospitable to the educational use of cable. (Author)
