Ever since the launch of his CityGrid local advertising network at the beginning of the year, Citysearch CEO Jay Herratti has been putting most of his efforts into building out CityGrid as the largest network of local advertisers and local apps. Citysearch is now simply a flagship publisher on the CityGrid network. To reflect this shift in focus, the Citysearch business unit of IAC (which includes CityGrid, Citysearch, Urbanspoon, and Insider Pages) is changing its name to CityGrid Media All of the local listings in Citysearch are available through CityGrid's APIs so that anyone creating a mobile app or local Website can grab business listings, addresses, phone numbers, photos, reviews, and more and build their own apps around them. CityGrid also matches local advertisers with these local publishers.
