The Hollywood case has a quirk that is relevent to the extensional content of HN:

West coast filmmakng started in the Bay Area (at the time the largest conurbation in the west) but moved south because of the year 'round weather.

But why the west? Because Edison controlled the filmmaking patents and demanded not just royalties but script oversight as well. By moving west, they could ignore the patents because they were simply too hard to enforce from such a long distance.

So ironically, given how things worked out, IP piracy is at the root of Hollywood.
