One thing I noticed:
For a long time, film manufacturers tried to outdo themselves producing emulsions with ever finer grain and better colors. Then came the CCD chip. When chips got good enough to do an 8x10 print with decent color, there was no point in having film that would produce roughly the same thing. At that point, photographers who wanted to keep using film began to move away from the usual fine grain saturated colors we were used to. The only places to go were cheap film with a ton of defects, X-pro and redscale. And for some reason, it also happens that these characteristics are available on the cheapest stuff we can put our hands on.
