Mobile consumption of webcast streams continued to drive growth: 37% of stream consumption transpired over iOS and Android devices.
Triton’s commentary accompanying this month’s report looks back at 2014, noting a 35% increase in Average Active Sessions (AAS) from Q1 to Q4 (Mon-Sun, 6:00am to midnight, domestic U.S. streaming).
When digging into the December metrics, we see that the Top 20 group as a whole enjoyed a 5% AAS growth from November (which suffered from reduced Thanksgiving listening). Individual percentage leaders were AccuRadio (+30%), ESPN (+22%), and Slacker Radio (+11%). As always, Pandora had the biggest session count, coming close to the 2-million milestone (1.97-million), a 5% month-over-month gain.
Year-over-year, the Top 20 group gained 12% from December, 2013.
A subset of Triton’s Top 20 is labeled Katz Digital Audio, and represents 11 radio groups. That cohort gained 7% month-over-month, and 6% year-over-year.
Here is RAIN’s historic trendline of the top-20 leaders:
