Unreliable Advertisement – The claim in the advertisement is something related to physical health, although the claims aren’t backed by any research. The statement “flu shots are so last year” suggests that you could potentially drink this water and avoid a flu shot, although, again, there’s no proof shown here that drinking this water typically causes an individual to be less likely to get the flu. The company has a lot to gain from making claims like this, although they seem to be intentionally vague in an effort to not be held accountable for the claim.

Reliable Advertisement- The advertisement shows the image of a doctor and also gives his credentials in an effort to support the product. In this scenario, the doctor seems to have the authority to judge whether or not the product is effective. Although people don’t like to see asterisk alongside the advertisements they see, in this scenario it quantifies the claims that are made rather than just airy promises. Also, the use of a regular doctor over a very famous one suggests that the doctor has no stake in the company and has little personal gain from appearing in this advertisement as opposed to a celebrity that would be paid a substantial amount for their appearance.

Attractive Advertisement- Oprah Winfrey, who is a well-known celebrity, is generally seen as a likable individual. Because Oprah Winfrey has had a stake in many media platforms (creating books, a well-known talk show, a TV network, among other things), it’s likely that people know her for one of these things, possibly garnering a positive outlook of her. As Oprah hasn’t been known to endorse things that she doesn’t personally, this also increases her credibility. People see celebrities like Oprah and are more inclined to think that because of their attractiveness and likability that consuming the products that they sponsor, they will also become attractive and likable, as in this case.
