Pandora Rules Ando Media's Rankers
June 10, 2010 at 3:31 PM (PT)
PANDORA ruled the day according to the ANDO MEDIA Top 20 Rankers for MARCH and APRIL. The release of the Rankers were delayed due, in large measure, to ANDO’s "ongoing MRC accreditation process," ANDO COO PAUL KRASINSKI said. "We have been bringing the MRC through the Ranker process every step of the way. As a result of their recommendations, there are a few changes we have implemented beginning with the MARCH data."
The key changes are:
1. All sessions greater than 24 hours have been truncated to 24 hours.
2. All sessions are now time-zone normalized based on our ability to determine the listener’s IP address and its corresponding location. Where this cannot be determined, location will be ascribed to the Central Time Zone to neither favor EAST or WEST COAST audience.
In most cases, these changes -- captured in the MARCH and APRIL Rankers -- have resulted in relatively minor fluctuations in the data.The top-10 rankings of Average Active Sessions were as follows (number in thousands).
