The Webcast Metrics October Domestic Ranker shows top streaming broadcasters all posting low double-digit percentage AAS (average active sessions) growth in the past month. Pureplay webcasters showed either modest growth of were flat.
One theory is that this growth was spurred by increased interest in political radio in the lead up to the November federal elections.
Cox Radio AAS jumped 30% since September in the M-Su 6a-12M ranking, and NPR Member Stations were up 28% (in the case of NPR, this is likely attributable to new stations's addition to the measurement panel). Cox and Clear Channel are both showing healthy growth over the past 12 months (AAS up 50% for Cox, and 87% for Clear Channel) and in calendar-year 2012 (49% for Cox; 40% for Clear Channel). (Note: Last late year, Clear Channel had just added other major broadcasters' streams to iHeartRadio, like Cumulus').
Pandora continued to pad to its enormous listening lead over the rest of the entire panel (Pandora's mere 3% increase in October represents a 40,742 AAS, which by itself is nearly twice the AAS of this ranker's current #6 webcaster). The leading webcaster is also up 35% this year.
Most other pureplay webcasters' performance wasn't nearly as impressive. Slacker is up 31% in the past 12 months, but that period began before it completely absorbed the AOL Radio streams. Note that former top pureplay webcasters 977Music.com and Digitally Imported are no longer in this ranking.
