Answer:
Use of personality symbols in the execution of ads/advertisement.
Explanation:
The use of personality symbols in the execution of advertisement usually entails creating/developing a central character around a product/brand through which the brand delivers its benefits.
Also, using a personality symbol helps to build a brand's identity in such a way that it stands out from its competitors.
An example is Marlboro as in the question above. A cowboy identity. It has made the malboro brand stand out for years such that anywhere you see a cowboy picture, your mind goes to marlboro.
Cheers.
