RAIN 2/25: Double-digit growth for 3 pureplays in Ando's December rankings

Posted on: 02/25/2011


Ando Media’s newly-released Webcast Metrics for December 2010 show three pureplay webcasters — Pandora, Slacker and AccuRadio — achieving double-digit growth over November.

Pandora, the far-and-away front-runner in the Domestic Mon-Sun 6a-12m ranking, grew 10% over November reaching an AAS (Average Active Sessions, which is essentially equivalent to AQH — i.e., average simultaneous listeners) of 542,863. Pandora’s AAS has more than doubled in the past year and is now more than double that of the top 5 broadcasters’ streaming audiences combined.

Meanwhile, Slacker’s AAS grew 25% over November, reaching 25,922 in the Domestic Mon-Sun 6a-12m chart, putting it in the #5 spot. That’s on top of the webcaster’s 45% growth from October to November 2010. The large growth could be explained by the fact that Ando Media says it is tracking Slacker’s mobile data “for the first time” in the December rankings (more on this below in our RAIN Analysis).

Finally, AccuRadio grew 30% in December — due in no small part to its popular holiday music offerings. AccuRadio’s AAS of 7,674 earned it the #11 spot in Domestic Mon-Sun 6a-12m ranking. (AccuRadio is run by the same folks that bring you RAIN everyday).

How did broadcasters fare in December? Well, #2-ranked CBS Radio posted an AAS growth of 3% and Clear Channel grew 8%. Citadel and Cumulus both took hits, dropping 13% and 19% respectively since November 2010. ESPN Radio grew 9%, as did Entercom. Most other broadcasters saw slight declines for the month in their streaming audiences, perhaps related to the fact that December is a big month for holidays from work, where the bulk of streaming listening occurs.

RAIN ANALYSIS: WHY THE BIG GROWTH FROM SLACKER? From July (when Ando first started tracking Slacker) to October, its AAS only grew 6%, but it grew 83% between October and December 2010 . What gives?

We believe that the answer lies with mobile listening. Though Ando’s footnote states that December is the first month with mobile audience data for Slacker, we believe it’s possible that the company measured Slacker’s mobile streams for part of November — e.g., starting sometime mid-month — and that December was the first month of complete mobile data for Slacker.

If true, that means that Slacker’s recent growth in Ando can give us a rough idea about what percentage of their audience is mobile — somewhere between 50% and 70%. That would roughly match Pandora’s announced percentage and is on-par with Slacker’s previous statements about half their users coming in via mobile devices (RAIN coverage here). — KH, MS


We’ve added two more speakers to the ever-growing agenda for RAIN Summit West 2011, set to take place in Las Vegas on April 11.

John Ousby, Director Broadcaster Services at vTuner will join us (pictured below left). Ousby also serves as a steering board member on both the Internet Media Device Alliance (IMDA) and RadioDNS.

Additionally, Rhapsody’s Senior Counsel of Legal and Business Affairs David Rosenberg will appear at RAIN Summit West 2011. Rhapsody has been in the news lately for challenging Apple’s new app subscription policies (RAIN coverage here).

RAIN Summit West 2011 takes place during the NAB Show in Las Vegas on Monday, April 11. It will feature a full-day’s line-up of insightful speakers and educational panels, as well as a special keynote from CBS Radio President and CEO Dan Mason. You can find out more about the summit, and register to attend, right here.


On-demand music subscription service Rdio joins Pandora, RadioTime and others on Roku — a web-connected TV box. Users need to subscribe to Rdio’s premium $10/month plan to use TV and mobile apps.

Interestingly, Roku CEO Anthony Wood said in September 2010 that Pandora was the second-most popular “channel” (or, app) on the device. “These music options are heavily used by Roku owners,” observes GigaOM (here). And really, that shouldn’t be too surprising (RAIN coverage here).


BMW’s 1 Series models will be the first to support the automaker’s Connected system, which connects to smartphones to stream Internet radio — among other web-connected functions. Engadget reports (here) the system requires a $205 add-on. Not bad, we suppose, considering the overall cost of a new BMW.

  1. Is it known if the Slacker data includes cached content along with streaming content or only streaming content?
