We find that advertising avoidance is similar in low and high clutter environments, so when there is more clutter, audiences really do see more advertisements. Doubling the clutter, however, does not halve the number of advertisements recalled, and in less clutter audiences are less likely to correctly identify the advertised brand in commercials they do recall. Overall, we find that the impact of clutter is not large, especially when compared to creative elements of executions.
