The repitilian part of your is interested in the quickness of the fast moving images. The limbic part of brain pays attention to the music(which to many is creepy, including myself, the uniformness of the people, and the chase of the person. The neocortex is appealed to when you begin to think of what Apple is trying to say the Mac is not.

1.Symbols:As seen in the commerical, the main symbols is 1984, a novel known for its portrayal of government surveillence and control and the government's trepassing on an individual's rights and the introduction of the Apple Mac.

2.Humor: The video is a way funny(at least in my opinion) because it has a random lady running with a huge hammer who throws it towards the big screen, breaking the source of oppression(Tell people to prepare for new!)

3.Plain Folks:The media uses uniformed people and security officers to tell the story.

4.Bandwagon: The media is trying to convince me that the Apple Mac will not be like 1984 but a breakthrough instead.

5.Testimonial:1984 is worldwide classic and on the top 100 books of all time and is familiar many avid readers and a requirement for those in many high schools.

I might put a more recent video later on just for fun, but this is what came into mind.
