Advertisement can be used to bring people together or inform people about a great new product that could make your everyday life easier. These are all great uses of advertising. It can also be used to promote nonprofit organizations and other such programs. I enjoy this christmas commercial from target. It has a simple message that is clearly delivered. Even Santa knows to run to target to get all of his last minute shopping done. This commercial has a great combination of humor and clear message delivery.
I think that both the bandwagon effect and visual techniques that produce involuntary effects factor into the success of this commercial. for the bandwagon effect they are getting at the fact that if Santa does it so much everyone else since he is the master at Christmas shopping. The slow motion run with his belly bouncing is humorous as well as the dramatic music triggers an involuntary positive reaction to this commercial.
