Data from three representative national surveys were studied to determine to what extent profiles of television viewers of different levels of viewing frequency fit with expectations based on theory and earlier research. A group of 4,552 respondents were surveyed in 1975, 1976, and 1978 by personal interviews and were classified as to status as nonviewers (less than one-half hour per day), heavy viewers (more than six hours per day), and viewers (one-half to six hours per day). Nonviewers and heavy viewers each comprised about 5% of the total pooled sample. Results indicated that the greatest difference between viewers and nonviewers lay in family structures, with nonviewers more likely to be never-married and childless, as well as being employed on the professional level. Heavy viewers were rated low in education, income, and employment status; most were female. As a whole, heavy viewers seemed to be removed from ongoing society, while nonviewers were better educated and about as well integrated and active as average viewers. (DF)
