“Audio never goes viral,” writes radio and podcast producer Nate DiMeo. “If you posted the most incredible story — literally, the most incredible story that has ever been told since people have had the ability to tell stories, it will never, ever get as many hits as a video of a cat with a moustache.” It’s hardly a fair fight, audio vs. cat video, but it’s the one that’s fought on Facebook every day. DiMeo’s glum conclusion is an exaggeration of what Giaever reads as the moral of her own story: “People will watch a bad video more than [they will listen to] good audio,” she says. Those in the Internet audio business tend to give two explanations for this disparity. “The greatest reason is structural,” says Jesse Thorn, who hosts a public radio show called “Bullseye” and runs a podcast network called Maximum Fun. “Audio usage takes place while you’re doing something else.” You can listen while you drive or do the dishes, an insuperable competitive advantage over text or video, which transforms into a disadvantage when it comes to sharing the listening experience with anyone out of earshot. “When you’re driving a car, you’re not going to share anything,” says Thorn. The second explanation is that you can’t skim sound.
