One of my favorite books is 1984. It is so mind blowing, and at the same time scary because of how many parallels we see in today's world. (FOXNews' "1/2 Hour News Hour of Hate" is one example.)
In the real 1984, Apple Computers launched a television advertisement during the Super Bowl. It is credited with starting the trend of "Super Bowl Ads." It was a teaser for the launch of the Macintosh entitled "Think Different."
Someone has taken that ad and turned it into an ad for Barack Obama entitled "Vote Different."
