A Cincinnati, Ohio based billboard company is breaking new ground for extending the reach of billboard advertising.  Norton Outdoor advertising is working with Florida based app developer, The Lazo Company, to offer a new “LAZO” app.  The app allows users to search billboard ads in up to a 50 mile radius from their current location.  Norton has over 900 billboards in the Cincinnati area, but only about 10% of them will be equipped with the location tracking software that allows the LAZO app’s use.   The app allows people to access billboard ads and special offers through their smartphone.  The system also allows advertisers to change their ads and offers depending on the time of day.  For more information, click here.
