This ad is promoting a drug that helps reduce heart problems and strokes. They brought a credible person to help apply to people. He’s a known doctor that seems trustworthy enough to help get people aware of two leading causes of death.
This advertisement is non-credible. The company trying to get people to buy their cigarettes use twisted wording to gain profit. Smoking is already bad for the health of someone. They lose credibility because they only want sales and profit.
This is an attractive source. I find it very effect because it’s trying to advertise a male perfume with a pretty good-looking guy. It catches the eye of the consumer and they probably believe that if they buy the perfume that they can be like the male model.
