Celebrating 50 years, the Journal of Advertising Research 50th Anniversary Special Edition is packed with analysis and insights from over 40 internationally renowned academics and industry leaders.

Even advertising has scientific laws, empirical patterns that generalize across a wide range of known conditions. These empirical generalizations provide us with benchmarks, predictions, and valuable insights into how the digital revolution may affect advertising. More than ever we need systematic research to understand the generalizability of our research findings.
DOMINIQUE M. HANSSENS
What has academic research revealed about the quantifiable impact of advertising on business performance? This article summarizes the advertising-related findings in a recent Marketing Science Institute book on empirical generalizations about marketing impact.
LES BINET and PETER FIELD
An analysis of 880 IPA Effectiveness Awards cases suggests that the following strategies increase advertising effectiveness in terms of sales and profit performance:
GIAN M. FULGONI and MARIE PAULINE MÖRN
Even with no clicks or minimal clicks, online display advertisements can generate substantial lift in site visitation, trademark search queries, and lift in both online and offline sales.
The number of times a brand visually appears in a video advertisement is correlated with higher correct identification of that brand within the advertisement.
EVA VAN REIJMERSDAL
Prominent brand placement affects memory positively, but affects attitudes negatively when audiences are involved with the medium vehicle, when they like the medium vehicle, or when they become aware of a deliberate brand placement (selling attempt). Brand placement can affect audience attitudes and behavior, without memory of the placement.
ED KELLER and BRAD FAY
Approximately 20 percent of WOM about brands refers to paid advertising in media. The level and effectiveness of WOM is substantially increased when stimulated, encouraged, and/or supported by advertising, increasing the probability by about 20 percent that a consumer will make a strong recommendation to buy or try a product.
PETER HAMMER, ERICA RIEBE, and RACHEL KENNEDY
Less clutter does not result in better brand identification. Advertisements recalled in high clutter are generally of better quality and are more likeable on average.
Based on the established empirical generalization that advertising elasticity is approximately 0.1, net profit is optimized by setting the advertising budget to be 10 percent of gross profit. If the elasticity is 0.15, then the advertising budget should be 15 percent of gross profit, and so on.
J. SCOTT ARMSTRONG and SANDEEP PATNAIK
Communicate a unique selling proposition. Ideally, it should be based on an important benefit; alternatively, and riskier, it could be based on a feature that clearly implies a benefit. It is effective if it is unique in the minds of consumers even though other brands could make the same claim. However, it is especially effective if it cannot be easily matched by competitors. This generalization, previously regarded as problematic, is supported by recent experimental evidence.
Factors that make shopping quicker result in increased shopper spending.
RAYMOND R. BURKE
In-store digital signage featuring “newsworthy” information (e.g., new items, seasonal offers, promotions) has a markedly favorable impact on sales. This effect is stronger for hedonic (food and entertainment) products.
Brand advertising often has a pronounced short-term sales impact. This impact decays over time. The most dramatic influence on short-term effect is creative copy.
ALAN G. SAWYER, HAYDEN NOEL, and CHRIS JANISZEWSKI
Spaced multiple exposures (distributed) produce greater learning than repeated exposures with short intervals (massed). Longer intervals between exposures result in better learning than shorter intervals.
JENNIFER TAYLOR, RACHEL KENNEDY, and BYRON SHARP
The advertising response curve is “convex”—the greatest marginal response is from the first exposures. As the number of cumulative exposures in a period increases, the marginal effect of the advertising drops.
YE HU, LEONARD M. LODISH, ABBA M. KRIEGER, and BABAK HAYATI
There is a greater than 50 percent chance that the typical TV advertising campaign will lose money both short term and long term. The risk of losing money fluctuates over the years, but has been over 50 percent. The average elasticity of TV advertising has fluctuated between 0.043 and 0.163 over the past 25 years.
KATE NEWSTEAD, JENNIFER TAYLOR, RACHEL KENNEDY, and BYRON SHARP
The total long-term sales effect of advertising depends (positively) on the size of the initial effect and (negatively) on competitive advertising. An advertising exposure typically has a half-life of three to four weeks.
BYRON SHARP, VIRGINIA BEAL, and MARTIN COLLINS
Television still has very high reach. Declining ratings are due to fragmentation (more channels) not to reduced TV viewing levels, which are remarkably resilient to social and technological changes and to the emergence of “new media.” Average ratings halve if the number of channels doubles. In addition, the Double Jeopardy law applies to TV channels. Bigger channels have more viewers, and these viewers watch for more hours.
Over the past 15 years, TV has not declined in its effectiveness at generating sales lift and appears to be more effective than either online or print at generating brand awareness and recognition.
OSCAR JAMHOURI and MAREK L. WINIARZ
Despite an increase in TV channels and fragmentation of audience, TV appears to retain its perceived clout among target audiences in Asia, Europe, and North America and holds across recent years. While the influence of digital media has grown, it has not caused a corresponding decrease in TV influence.
ERIK DU PLESSIS
Fast-forwarding TV commercials results in little difference in advertising recall and likability.
GERARD J. TELLIS
Research on over 260 estimates of advertising elasticity leads to the following important generalization. If advertising changes by 1 percent, sales or market share will change by about 0.1 percent—that is, advertising elasticity is 0.1. The advertising elasticity is higher in Europe relative to the United States, for durables relative to nondurables, in early relative to late stages of the product life cycle, and in print over TV. The advertising elasticity is lower in models that incorporate disaggregate data, advertising carryover, quality, and promotion relative to those that do not. The advertising elasticity is lower in multiplicative models relative to other model forms, such as the additive model. The advertising elasticity is invariant over the measure of the dependent variable or the method of estimation.
YORAM (JERRY) WIND and BYRON SHARP
A special conference on empirical generalizations (EGs) in advertising led to this special issue of the Journal of Advertising Research. It also generated a representative selection of 23 EGs that give a sense of how strong our scientific knowledge is about advertising, and where the gaps lie. While real advances in knowledge have been achieved, the list highlights significant knowledge gaps, particularly concerning advertising in the new fragmented interactive-media world. We surveyed advertising thought leaders on which of these empirical laws they felt were most important and most certain. Many of our empirical laws suffer from inadequate knowledge concerning the conditions over which they do and do not generalize.
