You mean old timey wimey marketing pre-internet? Just target people instead of Bob at 17th Rosewood St.

How about this, I set a preference for some stuff I am interested in and that’s what they can show me.

They don’t track Bob at 17th Rosewood St. They put him into groups of things they think he is likely to buy. Which is close to targeting people.

Multiple groups. And if you take the intersection of those groups you end up on 17th Rosewood St.
