In 2021, more than three-quarters of the time that US adults spent listening to ad-supported audio went to AM/FM radio. Podcasts trailed way behind traditional radio, capturing just 11% of ad-supported listening, while Pandora, SiriusXM, and Spotify each accounted for less than 10%. AM/FM radio held a majority share across adult age groups and was the most listened-to ad-supported audio not only in the car (88%), but also in the home (72%) and workplace (68%).
