Quase todas as rádios estão codificadas (PPM)

Agora foi a vez da Cox.

«Arbitron said that Cox Radio has agreed to encode its four radio stations in Houston for the Arbitron Portable People Meter radio ratings service. Cox had been holding out pending Media Rating Council accreditation in that market; that happened recently. The broadcast group has not yet said whether it will subscribe to PPM data from Arbitron. The audience research firm has not released a schedule for PPM implementation in Houston, the second market to go PPM after Philadelphia.»
