Numbers of podcast listeners continue to rise. The 2017 Infinite Dial report was released just last week. It’s an independent study that charts responses from a national telephone survey of randomly selected 2000 people and is considered one of the most trustworthy metrics by which to measure the podcast market. Monthly podcast listeners now constitute 24 percent, or 67 million, of Americans, a number that’s up three points from last year’s 21 percent, or 57 million, monthly American listeners a year earlier. In other words, the U.S. podcast audience has grown 14 percent growth year-over-year, which is healthy, though not as impressive as some in the industry had hoped for. The metric has doubled since a 2013 low of 12 percent.

But Retention Is Low

Infinite Dial also found that 40 percent of Americans had listened to at least one podcast before. Combined with the previous statistic, that 24 percent of Americans listen to podcasts on a monthly basis, and we can deduce that another 16 percent of Americans tried it out, and then decided they didn’t like podcasts. As podcast analyst Hod Pod covered earlier this week, Audible’s SVP of Original Content Eric Nuzum had a few thoughts on this: The root issue, Nuzum says, is either a lack of high-quality podcast content, or a lack of a way for people to discover it. The market gap between potential listeners and actual listeners represents a potential windfall for whoever can figure out how to fill it.
