Consumer perceptions of advertising clutter were examined through a national survey of 946 individuals. Perceived ad clutter across the spectra of advertising media, including newspapers, magazines, Yellow pages, direct mail, television and radio, was investigated to find out how such perceptions relate to consumers' attitudes toward advertising and their ad avoidance in each of these media. Furthermore, the study sought to determine the extent of the occurrence of clutter-related effects across advertising media, as well as the extent to which these effects are clutter-related. The findings indicate that the perception of advertising clutter is highest in television and direct mail, while the highest level of advertising-related communication problems was observed in television and magazines.
