Catalogs - offline and on-line, commercial and government. Deprived of constant noise and overstimulation of advertising, people will actively seek such information out, whether because they have a problem to solve, or just out of curiosity. All we're talking about here is switching from current "push" model of advertising back to "pull" model.
Who here never browsed a product or company catalog they found, just because they were curious?
I can almost feel the calm just imagining the world you're describing.
