Although expensive and sophisticated communications technologies tend to be popular as tools of rural development, the real frontier of communication in rural development is comprised of the simpler, less expensive technologies that put the means of communication into the hands of the rural population. Simple, inexpensive equipment such as audio cassette tape (ACT) systems and 8mm film technology shows the greatest promise in making the rural receiver more of an active participant in the communication process. ACT systems can be valuable tools in listening groups, training, information dissemination in family planning, and as tools for field workers; and these systems enable the information receiver to control the listening situation. More expensive, simple radio technology in basic village education and radio schools can also be an effective tool in rural development. (CMV)
