Radio underachieves.

A new study from eMarketer suggests that our medium—b over-the-air and online—get less money than their time spent would indicate. Meanwhile, TV and print get more than they should. Here’s the finding:

Medium Time Spent Share Ad Spending Share
Digital 47.2% 30.5%
Television 37.3% 41.2%
Radio 12.0% 9.3%
Print 3.5% 19.0%

eMarketer predicts that in 2014 the average time spent per day with all major media from U.S. adults will increase by 21 minutes from 2013, a total of 12 hours, 28 minutes.
