AbstractThe presence of positive entertainment (e.g., visual imagery, upbeat music, humor) in TV advertisements can make them more attractive and persuasive. However, little is known about the downsides of using too much entertainment. This research focuses on why, when, and how much to entertain consumers in TV advertisements. We collected data in a large-scale field study using 82 ads with various levels of entertainment shown to 178 consumers in their homes and workplaces. Using a novel web-based face tracking system, we continuously measure consumers' smile responses, and their viewing interest and purchase intent. A simultaneous Bayesian Hierarchical model is estimated to assess how different levels of entertainment affect purchases by endogenizing viewing interest. We find that entertainment has an inverted U-shape relationship with purchase intent. Importantly, we separate entertainment into that which comes before the brand versus that which comes after, and find that the former is positively associated with purchase intent while the latter is not. We conducted a large-scale field study by measuring entertainment 1 more naturally, in a web setting, and address three important questions. One, is there such a thing as having too much positive entertainment in ads? If too much positive entertainment can have detrimental persuasion effects in ads, and we find it does, then, two, it becomes important to understand how much entertaining content should be used. We find evidence that as much as a quarter of TV ads have passed the optimal level by dedicating too much of the ad time to entertain the consumer.
KeywordsThree, does it matter when during the ad the entertainment occurs? We find that where entertainment is placed relative to the brand's first appearance has significant impact on the consumer's intent to purchase the brand.This research also provides new conceptual understanding of how the level of entertainment in an ad is related to its attractiveness and persuasiveness in increasing purchases.To do so, we propose a new individual-specific measure to identify whether the viewer associates the entertainment experienced in the ad with the brand based on the order of its presentation relative to the brand. We define pre-brand-associated entertainment (preBAE) as that which precedes the first presentation of the brand and post-brand-associated entertainment (postBAE) as that which follows the first presentation of the brand. These types of entertainment a...
