According to February 2015 research by Edison Research and Triton Digital, another type of digital audio has gone mobile: podcasts. Fully 55% of US consumers ages 12 and older who had ever listened to a podcast said they used a smartphone, tablet or portable audio player most frequently to do so. This was up 4 percentage points year over year at the expense of computers, which saw their share drop to 42%.
As mobile usage becomes the norm, the shift to mobile podcast consumption is taking place alongside audience growth. In 2015, one-third of respondents said they had listened to a podcast, up from three in 10 in 2014. This works out to an estimated podcast audience of nearly 90 million, according to Edison and Triton. Monthly and weekly podcast listening were also on the rise. Fully 17% of respondents had listened to podcasts in the past month, and 10% had done so in the week leading up to polling—respective year-over-year growth rates of 13.3% and 25.0%. Read the rest at eMarketer.
