Gordon, funny you should mention Cinemascope... In most cases, it required a PAIR of anamorphics, and almost always a new pair of primary lenses, new apertures, a new screen (which some houses had to nearly remodel to accomodate), and in the case of the Fox 35mm magnetic/optical prints, two new sets of narrow tooth sprockets, and a special splicer... And, when was the last time you saw a Fox Scope 2:55 print with mag/op sound and narrow sprocket holes?... After they forced everybody to buy all this stuff, they shortly adopted the 2:35 format with standard sprocket holes (which we are still using) and shelved the original format, which COULD have done in the beginning... Cinemascope is a great format (you don't have to look twice to see the advantage) and it's by far the most light efficient of all current aspect ratios, so despite the fact that Fox bailed out on their original specs because of the cost of magnetic striping, and terrible magnetic head wear, it ended up partially as a benefit... Yet, it also closed many old houses which couldn't accept the screen, and was bastardized in lots of others with undersized apertures to more or less fit the screen they had... Scope and Dolby are something the customers can see and hear, but they'll never even notice cyan has arrived (unless it's so bad they can hear the difference), and could care less... As to its PR value as an enviornmental issue, most are so jaded by the constant bombardment of this stuff, it'll get lost in the shuffle... I'm not against something that is a demonstrable improvement, but cyan doesn't look to be, and having it shoved down our throats doesn't set well... The seat belt interlocking system of the early 70's is a great example of Big Brother doing "good" for us, and look how well that was received!...
