Newspapers, magazines etc. Basically however they want.

Those are just other forms of advertising, and the entire print industry is dying anyway. Where's the real answer?

Pull advertising isn't really the same kind of advertising as the predominant push kind, and it's the latter that's considered a problem. Let people decide where and when they want to be advertised to on their own. Let them visit exhibitions, trade shows, buy or browse product catalogs and shopper's magazines.

An article or review about a product written by an independent journalist that wasn't bribed is not an advert. Whether it appears in a printed publication or an online equivalent is immaterial.

But we don't want to spend our time researching possible new products. Empirically, we just keep buying the same thing until disturbed by some outside force.

What's the problem then? If our choices weren't at least little bit sticky, marketers would have us running around like headless chickens. Meanwhile, the "disturbing force" often is our own dissatisfaction, our search for novelty, and our changing needs. Things wouldn't stagnate.
