Triton Digital has released its monthly top 20 report for December 2011, based on its measurement of streaming platforms that subscribe to its Webcast Metrics service.
I’m weary of the microscopic monthly analysis of this data, so I decided to take a look at what has happened to the general space in a year.
- Pandora continues to completely dominate the measured pack. From January 2011 to December 2011 they grew their AAS (Average Active Sessions) by 88%. Session starts grew by less, meaning they did a pretty good job of holding on to their listeners. Their Time Spent was down, but only slightly from .83 to .75.
- Slacker was the big winner in terms of share of growth, they increased the size of their AAS by nearly 93%. The numbers are much smaller though, Slacker ended the year with an AAS of 50,767, in part thanks to the addition of AOL‘s streaming audience to its network. Slacker’s growing their audience and their tsl — gaining listeners and getting them to listen longer.
- Clear Channel’s online platform is iHeartRadio, although on the ranker it appears as Clear Channel. Their online audience grew as well, but not as much as you might expect given all the promotion. AAS is up by 48%. TSL down from 1.15 to .63 – more listeners spending less time listening.
- CBSRadio’s online platform suffered the loss of AOL’s streaming audience when they moved to Slacker. Their online audience dropped nearly 40% last year.
- ESPNRadio.com started the year on a big high of 17000, the largest standalone streaming number. At the end of the year they were still the biggest, although their number is down to 13,959 in December. It is possible given their singular focus on sports that January’s exciting football playoffs factor into that, I’m not sure.
