The “1984” commercial was a masterpiece of the genre. From history.com (h/t The Burning Platform):
During a break in the action of Super Bowl XVIII on January 22nd, 1984, audiences first see a commercial that is now widely agreed to be one of the most powerful and effective of all time. Apple’s “1984” spot, featuring a young woman throwing a sledgehammer through a screen on which a Big Brother-like figure preaches about “the unification of thought,” got people around the United States talking and heralded a new age for Apple, consumer technology and advertising.
The ad was directed by Ridley Scott, who directed the genre-defining dystopian science fiction film Blade Runner in 1982. The spot was in a similar vein, depicting a bleak and monocrhome future where a crowd of bald extras—many of them actual skinheads from the streets of London—stood before an enormous screen broadcasting a message of conformity. A runner enters, pursued by police, and hurls the hammer at the screen, destroying it just as the Big Brother figure announces “We shall prevail!” The text in the last shot makes the references to George Orwell explicit: “On January 24th, Apple Computer will introduce Macintosh. And you’ll see why 1984 won’t be like 1984.”
