In the advertisement, any technique that is used to influence human action by the alteration of visual or audible representations is called Propaganda.
There are various types of Propaganda Techniques. They are:
Beautiful People:
This propaganda technique is consists of the use of pictures of happy people, or sexually attractive people, or successful people to promote a brand.
Study the first and second pictures and you'd find that the first is uses very happy teenagers who are projected to seem to endorse or like the product.
The second picture is that of a pretty and nubile lady whose underarm is "BELOFIED".This tactic also falls under the Beautiful People technique.
Another reason that has been given for the use of happy people is that psychologists say that pictures of happy people evoke happiness in those who look at them. The more happiness is associated with the product, the more people are likely to buy.
Appeal to Authority:
This tactic always sells the notion that authoritative figures, celebrities, strong brands, or prominent figures support an idea, would buy a product, or take a course of action which the target audience is being programmed to take.
In the third picture, the authority figures being used are "Dentists" and Hygienists. So the Ad sponsors a campaign to say that people ought to purchase <em>Oral-B</em> because by virture of knowledge authority, the dentists and hygienists use it.
