It also must be much harder to actually watch reel-to-reels. You can just pop a DVD into any computer at any time without worrying about the additional logistics of space, trained projector operators, and time constraints.
do people actually refer to celluloid movie prints as "reel-to-reel"? i suppose the term is technically accurate, but i've never heard it used for anything other than the pre-cassette magnetic tape audio format (or i suppose very occasionally its data-tape derivatives).
I was a protectionist during college and your number one enemy with film is dust and dirt. I would imagine the prints would be unwatchable after a dust storm in Iraq.
