It was expensive and underpowered, but the Apple Macintosh still changed the world | John Naughton

After its hyperbolic, Ridley Scott-directed launch 40 years ago, Apple's all-in-one computer was a commercial flop. And yet its impact is still being felt

Forty years ago this week, on 22 January 1984, a stunning advertising video was screened during the Super Bowl broadcast in the US. It was directed by Ridley Scott and evoked the dystopian atmosphere of Orwell's Nineteen Eighty-Four. Long lines of grey, shaven zombies march in lockstep through a tunnel into a giant amphitheatre, where they sit in rows gawping up at a screen on which an authoritarian figure is intoning a message. Today, we celebrate the first glorious anniversary of the information purification directives," he drones. We have created, for the first time in all history, a garden of pure ideology."

Then the camera turns to a young woman carrying a sledgehammer, hotly pursued by sinister cops in riot gear. Just as Big Brother reaches his peroration, Our enemies shall talk themselves to death, and we will bury them with their own confusion. We shall prevail!" she hurls the hammer at the big screen, which explodes in a flurry of light and smoke, leaving the zombies open-mouthed in shock. And then comes the payoff, scrolling up the screen: On January 24th, Apple Computer will introduce Macintosh. And you'll see why 1984 won't be like 1984'."
