While streaming video content is a hot topic, its reach among all adult age groups in the U.S. is dwarfed by streaming audio and radio content.
As you can see from the chart, 40% of 18-24s listen to streaming audio or radio weekly. That reach falls as subjects age, but is still a strong 1 in 4 35-54s.
Obviously, streaming audio is technically easier (with a lower bandwidth requirement). It's easier to enjoy audio on mobile platforms and while driving. And as MediaPost points out, "Radio and any other kind of streaming can be done on the computer while working on the same device -- whether for the purpose of providing background music, sports commentary or other forms of talk-based content."
Consultant Mark Ramsey commented, "For anyone who continues to chirp that 'Pandora is not radio,' I suggest you tell that to the advertiser who sees up to 40% reach on an ad-supported audio platform."
