Supposedly free of tracker errors, Pandora's audience soared 40% month-to-month in Triton Digital's newly-released Webcast Metrics for August 2011, while nearly all other webcasters also grew.
The top-ranked Pandora now commands an AAS (Average Active Sessions, which is essentially equivalent to AQH — i.e., average simultaneous listeners) of 676,801 -- nearly double the combined audience of the other 19 ranked webcasters in the Domestic Mon-Sun 6a-12m daypart. Pandora's numbers have for the past few months been affected by the omission of tracking code in some of their mobile apps.

Most other webcasters also saw gains over July, though many were only regaining ground lost during summer. For example, #2-ranked CBS Radio was up 16% month-to-month, but their AAS of 97,712 is lower than where it was in April (98,676). Clear Channel was in a similar position, growing 14% month-to-month but reaching an AAS lower than April's.
Slacker was the only webcaster in the Top 20 ranker to show a month-to-month decline, but even then it was very slight.
August also saw several webcasters reach new record highs for 2011. AccuRadio, Digitally Imported Inc., EMF Corporate, Greater Media and Radio One / Interactive One -- not to mention Pandora -- all reached new year-high AAS levels.
