>And in other cases, your customers just cannot be reached by ads at all - eg: military contracts. Overall I agree with what you wrote but I just to highlight that you can absolutely target military contracts with ads. If you visit Washington, DC you will see ads for fighter jets, missiles and random obscure military systems by Raytheon and other contracts at bus stops. Guess what - military planners and decision makers live in DC and use public transport. While conversion rate is minuscule, you need only one multi-billion military contract to pay for a lot of ads. Digitally you can target by geo location (Pentagon/military bases/installations) or even for example microtarget places where key senators live. Lots of options.
