To give a greater voice to diary-rated markets, the ratings service adds four new seats. Those are being taken by Erik Hellum of GAP West Broadcasting; Frank Osborn of Qantum; Craig Jacobus of South Central Communications; and Dan Savadove of Main Line Broadcasting. There’s also a new PPM set, to be taken by Greater Media Philadelphia manager John Fullam. Plus additional positions for Network Radio (David Landau of Dial Global), Digital Radio (Deb Esayian of Emmis Interactive), and Public Radio (Bill Davis of Southern California Public Radio). Urban and Spanish representation is beefed up by adding Deon Levingston of Inner City Broadcasting and Jeff Liberman of Entravision. Arbitron also re-stocks the Council with replacement reps for a Spanish language seat (Univision Radio President/COO Gary Stone) and Research (Amy Vokes of Radio One). The Council’s next meeting is May 11-12 in Annapolis, MD, near Arbitron’s headquarters in Columbia, MD.
