Typesetting
Before the 1980s, almost all typesetting for publishers and advertisers was done by specialist typesetting companies. These companies performed keyboarding, editing and production of paper or film output, and formed a large component of the graphic arts industry. In the United States, these companies were in rural Pennsylvania, New England or the Midwest where labor was cheap, and paper produced nearby, but still within a few hours' travel time of the major publishing centers.
