Digital audio had the largest growth in ad revenue over the past year compared to other digital sectors, according to a recent report from the Interactive Advertising Bureau conducted by PwC.
Why it matters: As listening grows in streaming music and podcasts, more ad dollars are moving to the mediums.
By the numbers: Digital audio — comprised of podcasts and streaming music and radio — reached $4.9 billion in ad revenue last year, up 58% from the year prior.
Yes, but: Digital audio is still a much smaller piece of the revenue pie compared to other formats.
