Anderson, M.T. Feed.

Set in a future world where television and computers are connected directly into people's brains when they are young, Feed is a thought-provoking novel that will make you reexamine our present-day consumer society.  In this future society, which is dominated by corporations and the media, teens--due to the feeds in their heads and the constant stream to their brains to consume--are empty-headed kids who are driven by shopping and the pursuit of mindless entertainment.  However, there is one girl unlike the others who, because of receiving her feed much later than the others, has the will to fight the feed.  This is a terrific satire, and a book that you will not forget.
