The boundaries of the film frame can take many forms. The history and evolution of formats is as long as the history of the cinema itself. (Hence the need for our Aspect Ratio Guide). However the heated development of widescreen formats we now associate with movies began in earnest in the early 1950s in the battle to compete with television which at the time was seen to be keeping people entertained at home preventing them from heading out to the movie theater.
Nonetheless, for as long as Hollywood has been trying to outrun television, we’ve had the need to shove those movies back into the tube with black bars at top and bottom, as practice called “letter boxing,” or by fitting the image into the vertical space and “cropping” off the sides.
The first standardized television format became 4:3 or “standard definition video” and later 16:9 with high definition video, which at 1.78:1 was a close match to 1.85:1 widescreen cinema.
