ABN Radio, the largest farm radio network in Ohio, will relocate its headquarters to Ohio State University, where it will share a building with WOSU Public Media next year. It will renovate space recently vacated by WOSU, which opened its new digital radio facility in the building. Tom Rieland, WOSU’s g.m., says the partnership “could lead to many interesting programming collaborations.” ABN, heard on 65 stations, is run by a small, owner-operated company that runs BARN (Buckeye Ag Radio Network), according to WOSU. (Correction: It is not operated by the trade publishing company DTN, whose name appears at the bottom of ABN’s website.)
