I’m curious how you’d define advertising. Is it just something applied to another form of media? Would you count an end cap at the super market? Does the McDonald’s logo on the big sign you can see from the highway count? Or the coke machine inside?

Any definition I could pick would be more than none, which us what we have now.

An easy start is all billboards, everything ublock origin considers an ad, TV/radio/magazine ones.

All very unambiguous
