Okay, you poked the science writer with a stick: analogue film *is* also digital -- it's x number of still images per second run through a camera, and then later run through a projector, right? In the early days of cinema, the rate per second was below the brain's flicker-fusion rate -- the rate at which flickering images appear to fuse into a continuous stream in the mind's eye, roughly 75 per second -- and that's why they used to be called "The Flicks." So-called digital video is doing essentially the same thing, except that it's turning the camera on and off at an arbitrarily high speed to capture individual images and then threading them together for playback above the flick-fusion rate.
