[QUOTE=alapin;1188707]Check out this article I found today on the net.
Something that jumped right out:
"George Eastman transformed photography from an arcane hobby into a mass commodity with his $1 Brownie in 1900"
Unless my sense of it's history is way off, wasn't photography still largely business at that point? Though I suppose it could be seen as a hobby with the well off "early adopters" of the original Kodak roll camera and amateur artists.
