Monday passed with still no official announcement that Clear Channel has signed a deal with Arbitron to subscribe to PPM in all of the Top 50 markets where Arbitron plans to roll out the electronic ratings service. Clearly the deal has been struck, but, as with so many things, the devil is in the details. As RBR reported yesterday (6/25/07 RBR #123), The Media Audit insists that Clear Channel and other broadcasters will still provide funding for testing of its challenger to PPM being developed with Ipsos. Arbitron did announce late yesterday that Magic Broadcasting had signed a multi-year deal for PPM ratings in Los Angeles. Magic owns KDAY-FM and KDAI-FM. LA is scheduled to get PPM measurement next January.
