Mais um trunfo para o PPM

A cadeia gigante CBS anunciou que vai passar a trabalhar com o PPM para medição de audiências nos EUA.

Isto motiva um comentário na RBR:

«RBR observation: Is it all over? Has PPM won? Not necessarily. CBS is a big fish, but Clear Channel is even bigger in radio. Should the remaining members of the Next-Gen group disagree with CBS and select the Media Audit/Ipsos entry for radio ratings, CBS would eventually have to go along. Arbitron's PPM is dependent on broadcasters encoding, leaving gaps where stations refuse to do so - as Cox and Radio One have demonstrated in Houston. One of the attractions of the Media Audit/Ipsos system is that it prefers encoding, but still produces ratings via sound-matching for stations that refuse to encode. We hear that a handful of other significant group owners, including some Next-Gen members, are considering signing PPM agreements as CBS has done. But the opera ain't over until the fat lady sings - and the fat lady lives in San Antonio.»
