One type of testimonial propaganda is an ad with a celebrity endorsement, like when a well-known actress appears in a makeup ad. The public tends to like and trust famous people, and testimonial propaganda takes advantage of this.
Britney Spears, Michael Jackson, and Beyonce are just a few of the famous people who have been in Pepsi Cola ads. By being in these ads, these celebrities are giving the impression that they like and drink Pepsi products, which makes them more appealing. This is a type of propaganda based on personal stories. Politics can also use propaganda based on what people say. Politicians make a statement when they say they support a certain candidate in public. This is an important part of the democratic process in the United States. For example, when Republican Colin Powell backed Democratic presidential candidate Barack Obama in 2008, he was not only saying who he thought should win the election, but also what he thought about the state of his party.
