‘Dear Mr President‘ is PEPSI’s advert (thought and thus, it would be so much cooler if it was Mr PEPSIdent); you are suppose to answer this question: ‘what would you say to the man who is about to refresh America?’. PEPSI then becomes the channel, the messenger, the carrier, the pigeon, the media between the audience and the target. Very clever. An banking on one of the most widely liked presidents on the history of the United States of NorthAmerica, that is also clever. You can see there loads of videos and short textual messages from famous and the rest of us.
Its all here.
