A better example would have been printers. Newspapers employed a lot of printers to print those papers. Eventually these printing jobs got consolidated. For example the Boston Glob (tm) is now printed by the same compay that prints the Boston Herald.
A friend of mine used to be a newspaper printer. He now washes dishes for a living.
