And I'd assume that the various ad agencies would be multisystem in scope (although they would each have their headquarters at one specific Corporate world).The most orderly and 'lawful' system of government within GalCop is the corporate state. This system comes about when either a single, or more often, a group of powerful and affluent companies take de facto control of a planetary system.
Edit: and I'd asume that "orderly and lawful" only applies to protecting the flow of trade to and from the planet... on the ground, everything, including justice, will be for sale!
