To help improve televised extension education, a study was made of the interests and characteristics of the potential audience (9,300) of PTVC, a community antenna television system in Carbon County, Pennsylvania. A checklist questionnaire survey drew 160 usable responses from the communities of Jim Thorpe, Lehighton, and Palmerton. Data on viewers and nonviewers, age, sex, educational level, town of residence, interest subjects, and preferred viewing times and days were gathered and correlated. These were among the findings and conclusions: (1) 45% of the sample were regular County Extension Service viewers; (2) the average PTVC viewer has a high school education; (3) public affairs, safety, and emergency planning had the highest overall interest ratings, followed by family responsibility, do-it-yourself, leisure time, financial planning, interpersonal relations, garden and lawn, and meal preparation; (4) effective Extension telecasts in Carbon County must provide for persons over 40, a certain educational level, audience feedback of special public affairs topics, and subjects for special interest groups.
