Clear Channel up 10% during promotion of iHeartRadio relaunch

Webcast Metrics from September 2009 to September 2011Triton Digital has released its Webcast Metrics for September 2011 -- the month that saw Clear Channel relaunch iHeartRadio with Pandora-like features. A beta of the new service was released in early September (more here) and a star-studded concert promoting iHeartRadio took place in Las Vegas on September 28.

Did the new product and heavy promotion boost Clear Channel's audience? The broadcaster's September AAS (Average Active Sessions, which is essentially equivalent to AQH — i.e., average simultaneous listeners) grew 10% over August in the Domestic Mon-Sun 6a-12m daypart.

That said, Clear Channel's September AAS is less than 1% higher than its previous peak, which came in December 2010. Plus, the month-to-month increase is actually lower than the 14% growth Clear Channel achieved from July to August 2011.

In other words, while the new iHeartRadio most likely contributed to Clear Channel's growth, other factors -- like the post-summer, pre-holiday growth seen by most webcasters -- may have been involved as well. Since the official launch of the new iHeartRadio took place in late September, we may not see its influence until the October Webcast Metrics are released.

Most other webcasters saw growth over August. The strongest came from EMF Corporate, with an AAS increase of 30% (3,874) to reach 16,662.

Pandora grew 11% (76,015) from August and is up 85% from September 2010. (By comparison, Clear Channel grew its AAS by 8,294. In fact, Pandora's AAS growth alone from August to September represents over 83% of Clear Channel's total AAS.)

Pandora's AAS (752,816) is over eight times that of #2-ranked CBS Radio, which saw a 4% decrease from August and is within 3% of losing its place to #3-ranked Clear Channel.

The strongest year-over-year growth came from Slacker (109%, though their mobile audience was not tracked in September 2010), Pandora (85%) and AccuRadio (40%).

The combined AAS of the Top 20 webcasters increased over 8% from August and over 48% from September 2010.
