The authors examine the predictors of ad avoidance in four media: magazines, newspapers, radio, and television. A national survey of 946 adults found that ad avoidance is most prevalent for television and magazines. The predictor variables were demographic characteristics, media-related variables, attitudes toward advertising in each medium, and communication problems related to advertising. Ad perceptions were the strongest predictors of ad avoidance and were best in differentiating print from broadcast media. The results indicate that age and income were the best demographic predictors across media. Breadth of media use was an important broadcast media predictor. Among the communication problems considered, search hinderance had the greatest effect on ad avoidance.
