Philip Elmer-DeWitt on a study of when and how Americans tune into public radio. From Fortune:
[more] than 8,000 Americans who listen to National Public Radio on their iPhones (rather than, say, their car radios) between 8 a.m. and 10 a.m. on a typical weekday morning—one of the more surprising results of an hour-by-hour study of listener habits released by NPR Wednesday.
Guilty. Instead of radio I stream all kinds of shows on my iPhone while riding the subway into Manhattan.
