This campaign was meant to expand the sales of Coca Cola especially to those that hadn't tried it before. It was an extremely successful campaign with an increase in sales dollars of 2.5% in the last year. The reason for this is because the message of the campaign is to share, and someone sharing a coke with a friend is essentially advertisement in itself.
In this advertisement it starts out with a girl buying cokes from a store and having obvious interest in the cashier. She continues coming back to get more and more cokes with her and her friends, who seem to just have the most wonderful times while drinking coke. Then at the end of the commercial the girl finally invites the cashier to come outside and party in the streets with them (or whatever it is they are doing).
The reason that this commercial was so successful was because of the use of the rhetorical triangle. From start to finish we see plenty of pathos: the happy music, the chemistry between the girl and the cashier, the fun that these kids have together, the heartfelt love story theme, and last but not least when the girl grabs the cashier's hand at the end of the commercial. These are all examples of things that appeal to our emotions, thus being categorized as pathos. Although ethos is not quite as apparent in this commercial as pathos it is indeed still there. I found ethos in this commercial with the use of the famous coca cola logo. The logo is placed fairly often throughout the advertisement, this is an example of ethos because what is more credible and well-known than the coca cola logo? I had a hard time trying to find anything related to logos in this commercial considering that the commercial itself if fairly illogical (I kind of doubt that coke really makes people have that much fun). So, i am just going to say that the appeal for this particular commercial is mostly pathos and ethos.
This campaign was a very well thought out plan to bring sales up and was extremely successful in doing so. I am sure that coca cola will have more great ads to come in the near future and i am excited to see what they bring to the table.
