The latest ‘Infinite Dial’ report from Edison Research and Triton Digital has been released, exploring how Americans are listening to radio and music online. Among its findings: 47% of Americans say they have listened to online radio in the last month – up from 27% in 2010 – with the figure covering AM/FM stations online as well as “streamed audio content available only on the internet”. For just 12-24 year-olds, that figure rises to 75%, with online radio now reaching an audience of 94m Americans every week across all ages. Pandora remains the runaway leader in terms of awareness. 70% of people surveyed were aware of Pandora, compared to 48% for iHeartRadio, 47% for iTunes Radio, 40% for Rhapsody and 28% for Spotify. In the last month before the survey, 31% said they’d listened to Pandora, 9% to iHeartRadio, 8% to iTunes Radio and 6% to Spotify, although among 12-24 year-olds, those percentages rose to 55%, 12%, 17% and 16% respectively. More stats: 33% of respondents had used YouTube in the last week to watch music videos or listen to music, but that rose to 60% for 12-24 year-olds. But the biggest source of music discovery? AM/FM radio, with 75% of respondents who think it’s important to “keep up to date with music” citing it as a source.
