Long ago I learned that using irony and sarcasm is not the best way to communicate a message–often times people are not on the same page in terms of getting the humor. Advertising, though, seems to have changed the game a bit. These days it is *the* way to reach young people. This anti-Exxon ad deals in the contemporary currency of irony and culture jamming. Does it work? It will certainly reinforce the beliefs of those who agree with the message (such as myself). I wonder, though, if it can reach a wider audience and be effective. What do you think?
