U.S. consumers on average spend more than four hours a day with audio content, with radio as the most popular format among all ages, according to a quarterly report
by Nielsen and Edison Research.
About two-thirds (67%) of audio time is spent with radio among all adults ages 18 or older. However, there are significant differences among age groups. About three-quarters (74%) of daily audio time is spent with radio among people 35 or older, compared with 45% for persons ages 18 to 34, the research shows.
