Collage and Montage

I am more and more inclined to think that a montage is very much like a collage.
When young, I used to paint and then I moved on to sketching; somewhere in between I started to explore moderns art and discovered collage. Oh boy it was like love at first sight! Collage is pure creativity and freedom. To me it is a very powerful art form. I wish I had more time to explore it more - or probably more money to just focus on it instead of the rat race.
Now I am feeling that montage is similar to collage... probably I do not refer to montage in its true self when I compare it with collage, yet it is - I think you get it.
