Arbitron commercializes PPM ratings in five new markets
Arbitron announced today that it has commercialized its PPM radio ratings service in five new local markets.
In what could bring more dollars to radio, Arbitron unveiled its Promo OptimiXer service, a single-source, cross-platform ratings tool designed to help broadcast and cable networks evaluate the return on investment that radio and television ``tune-in'' campaigns deliver in terms of audience ratings to the programs being promoted.
