Strout R (2008) in his case material “Pepsi and Madonna” examines the use of entertainment personalities in advertising commercial products through the example of Pepsi's use of Madonna. It illustrates how companies try to tie the success of the artist to their product. The paper demonstrates the need for clear evaluation of the celebrity endorser, their public image, and if the relationship between the artist and the product applies to the advertising rules. When Pepsi picked Madonna, the choice turned out to be too hot to handle. The $5 million campaign featuring the extravagant vocalist had to be scrapped because of its links to Madonna's highly controversial "Like a Prayer" music video."

David H. Silvera, Austad B (2008) in their research topic have examined whether consumers infer that celebrity endorsers like the products they endorse, and presents a model using these inferences and other characteristics of the endorser to predict attitudes toward the endorsed product. Participants in two experiments examined written endorsement advertisements and were asked to infer the extent to which the endorser truly liked the advertised product and to rate the endorser's attractiveness, similarity to themselves, and knowledge of the product. Attitudes toward the advertisement, the endorser and the product were also measured. The resulting model indicated that product attitudes were predicted by inferences about the endorser's liking for the product and by attitudes toward the endorser.

Goddard L, Wilbur N (2009) in their study provides a starting-point for further research on negative information transference in the celebrity endorsement relationship. It is crucial that organizations be aware of the risks associated with using celebrities to endorse their stores and products. Given that these results provide tentative support for the commonly held belief that a decline in the celebrity's image can impact the image of the brand, it is important that retailers carefully choose an endorser who currently has a good image and will likely be able to uphold this image in the future.

Dix S, Pougnet S (2009) in their research have found that Athlete role model endorsers have a positive influence on young adults' product switching behavior, complaint behavior, positive word-of-mouth behavior and brand loyalty. This confirms the assumption that sports celebrities are important socialization agents and can have significant impact on purchase intentions and behaviors. This research provides useful insight into the influence of athlete endorsers on young adults and suggests athletes have a positive influence on young adults' behavioral intentions in switching products, generating word-of-mouth and establishing brand loyalty.

John Deighton : The Effect of advertising on brand switching and repeat purchasing, The authors examine switching and repeat purchase effects of advertising in mature, frequently purchased product categories. They draw on consumer behavior theories of framing and usage dominance to formulate a logic choice model for measuring these effects. They estimate the model using single-source scanner data. Their results suggest that advertising induces brand switching but does not affect the repeat purchase rates of consumers who have just purchased the brand, a result consistent with usage dominance rather than framing. They find the switching influence to be largely confined between the current and previous purchase occasions. They illustrate the magnitude of this effect and explore potential profitability.
