Question: 1. With reference to the three-exposure hypothesis, explain the difference between three exposures to an advertising message versus three exposures to an advertising vehicle.
2. When an advertiser uses the latter, what implicit assumption is that advertiser making?
3. Describe in your own words the fundamental logic underlying the principle of recency (or what also is referred to as the shelf-space model of advertising). Is this model always the best model to apply in setting media allocations over time?
