Ask HN: Can Google AdWords help local pizza?

Search pay per click has become a dominant ad platform for advertisers. Google. yahoo and MSN are trying to attract local advertisers by offering geo and demographic targeting. Still a look at their advertisers suggest that local barbers, plumbers and pizza parlors are still not advertising on search engines.

Yellowpages and local newspapers are still the preferred channel for these geographic businesses. The question is what role will internet play in local advertising and in what format?

I hope this hacker site can answer this question.
