“Montage” in the sense of using multiple images to create a single image has been around since the 19th century. In the early 1900s, the term “montage” has been used for an image collage, and since then the term has been used for a similar concept where multiple images are juxtaposed.
The word’montage’ is a shortened form of the word ‘Montage’, and it was used for the film in the late 1950s. It’s a rather odd word, like the word ‘Montage’ and even though it’s very common nowadays, the term isn’t widespread outside of the United States. But the term “Montage” has been used for a long time.
