City, county, regional and state governments - first of all in the U.S - sponsor offline and online periodic content about their locations. These economic development magazines and business journals try to highlight the sponsoring locations.
My approach to economic development publishing differs a bit. I say you should not sponsor but own a business journal. And I guess you should not produce offline papers, but focus on online content.
But, at the end of the day, you should start your online [your location] Business Journal, as your new economic development blog.
