Since 1977, the Academy Awards have handed out an Oscar for Best Visual Effects. So it would stand to reason that by combining them, you'd have a chronology of the best special effects ever made.

Watch the lightsabers of Star Wars give way to dinosaurs of Jurassic Park and the paint-filled heaven of What Dreams May Come, and see just how much the rise of digital has changed the medium with Avatar, Hugo and The Life of Pi. It all takes less than five minutes.
