Radio One Signs On For PPM In Philly, Los Angeles Arbitron announced Friday that Radio One, which for some time has been reluctant to encode its stations for Arbitron's Portable People Meter audience measurement system, has agreed to encode its radio stations in Philadelphia and Los Angeles to work with the PPM. No further details were given.
Last year, Radio One quietly began encoding its stations in Houston, where Arbitron is currently conducting a PPM test.
