Every 0.9 seconds, another podcast episode is released into the world.
Think about that. Roughly 67 new episodes every minute. Nearly 100,000 every day. More than 35 million a year.
That’s a colossal amount of content for a medium that’s just a year older than legal drinking age. I started putting podcasts in my ears in 2006, when most people had never heard of them.
In February 2013, I wrote a post on this blog titled In Praise of the Podcast. I said, “Podcasts are to media what Trefoils are to Girl Scout Cookies.” In other words, most people knew they existed, but relatively few were consuming them. I was among the early enthusiasts.
My podcast habit began in 2006 when I downloaded one podcast at a time to my 1-gigabyte Apple iPod Nano. Yep, I connected my Nano to my laptop by the old iPod connecting cord with the huge plug. Soon I was exploring an idiosyncratic variety of free podcast programming, from business advice to comedy, news and offbeat subjects. I was hooked.
From Nerdy Novelty to $9 Billion Industry
On October 9, 2026, Freakonomics Radio released a fascinating episode titled It’s Show Business, Baby!. Host Stephen Dubner devoted more than an hour to examining the strange economics of podcasting, a medium that has grown enormously but still seems uncertain how to operate as a business.
Consider the numbers presented in the episode: Podcasting began in 2004. Today, the estimated worldwide audience is 620 million people. Annual global podcast industry revenue is estimated at roughly $9 billion.
That sounds enormous, until you hear Dubner explain that podcasting is a smaller business than bowling, American pet grooming and boarding, or American funeral homes.
And then there’s that mind-boggling statistic about new episodes appearing every 0.9 seconds, calculated by Will Page, Spotify’s former chief economist.
Page describes the podcast universe as a “sea of niches.” There are podcasts about everything: sports, politics, business, history, religion, true crime, science, entertainment, self-improvement and thousands of obscure interests that traditional broadcasters wouldn’t dream of serving.
Podcasting has accomplished something extraordinary: It’s now possible for almost anyone with something to say to reach a potentially worldwide audience, without owning a broadcast license, newspaper, printing press or television station.
Everybody Can Make a Podcast. Who’s Making Money?
One of the more startling observations in the Freakonomics episode is the suggestion that only about 1% of podcasts are profitable. That’s a widely repeated estimate rather than a documented industry statistic, but even allowing for uncertainty, it reveals something about the industry’s economics.
Podcasting has produced its share of celebrities and enormous financial deals. Joe Rogan, Alex Cooper and other personalities have become valuable podcasters. Spotify and Amazon have spent hundreds of millions acquiring podcast businesses and talent.
But the vast majority of podcasters operate on an entirely different scale. Some earn modest advertising or subscription revenue. Others produce shows to promote their businesses, build reputations, cultivate communities or simply pursue personal interests.
Plenty make nothing at all.
Unlike traditional broadcasting, podcasting doesn’t require a large audience to justify its existence. A program attracting a few hundred devoted listeners can still be worthwhile to its creator.
That’s one of podcasting’s great strengths. It’s also one reason its economics are so peculiar.
A Marketing Medium We Still Can’t Properly Measure
Here’s the part of the Freakonomics discussion that I found particularly interesting as a lifelong marketer: twenty-two years after podcasting began, the industry still lacks a universally accepted system for measuring audiences and advertising exposure.
Advertisers can buy podcast placements, and sophisticated measurement tools certainly exist. Downloads, streaming activity, listening behavior, promotional codes, website visits and other indicators can provide useful evidence of advertising effectiveness.
But a download isn’t necessarily a listen. A listen isn’t necessarily an advertisement heard. And an ad heard isn’t necessarily one that produces a sale.
Complicating matters, podcast consumption takes place across Apple, Spotify, YouTube and numerous other platforms, each with its own methods of gathering and reporting data.
Jim Bankoff, CEO of Vox Media, told Dubner that this fragmented measurement system leaves media companies struggling to combine data and demonstrate value to advertisers.
This year, the advertising agency Oxford Road helped convene the Alliance for Measurement in Podcasting, or AMP Accords, to address these shortcomings.
Think about the implications. Here is a global medium with hundreds of millions of listeners, advertisers eager to reach them, and an industry still working out what constitutes a reliable advertising impression.
For marketers accustomed to standardized audience ratings and digital analytics, that’s a substantial handicap.
It may also represent an opportunity. Podcast audiences often select programs deliberately, return regularly and develop unusually strong relationships with hosts. That combination can be attractive to advertisers, even if the precise value of the exposure remains difficult to quantify.
In my 2013 blog article, I suggested that podcast advertising could work because it offered an uncluttered environment and an opted-in audience.
I still believe that, even though podcasts now have more ads than they once had. The challenge is proving their value consistently enough to attract ad spend.
An Unlimited Supply of Content. A Limited Supply of Attention.
Podcasting has another problem: discoverability.
When I started listening in 2006, finding interesting podcasts was relatively easy because there weren’t that many. Today, the choices are practically limitless.
How do you find shows you’d love that you don’t even know exist?
Recommendations, search results, charts, social media and increasingly YouTube provide some answers. But discovery remains surprisingly imperfect for a digital medium that’s been around for more than two decades. And it takes time on the consumer’s behalf to try new podcast series and decide to stick with them or jump ship. So many podcasts, so little time.
The Freakonomics episode also explores a development likely to make this problem considerably worse: artificial intelligence.
Jeanine Wright, whose company Inception Point AI produces AI-generated programming, told Dubner that the company had created approximately 15,000 active shows and more than 300,000 episodes. Production costs can average around one dollar per episode.
One dollar!
AI could make useful audio content available on subjects too specialized to justify traditional production costs. But it could also flood the podcast universe with low-quality, repetitive or untrustworthy material, also known as slop.
And while the supply of programming is virtually unlimited, the supply of human attention is not. Every 40 minutes spent listening to a mediocre AI-generated podcast is 40 minutes unavailable for something better.
With a new episode appearing every 0.9 seconds even before AI production reaches its full potential, the competition for our ears will only intensify.
The Medium That Refuses to Behave Like Other Media
Perhaps the most intriguing insight from Freakonomics is that podcasting has succeeded partly because it developed without the tightly controlled distribution systems that characterize other media.
For years, Apple made it possible for virtually anyone to distribute podcasts to the world without charging either producers or listeners. The open RSS (Really Simple Syndication) technology underlying podcast distribution allowed shows to appear across competing platforms.
This open environment was wonderful for creators and consumers, but produced some peculiar financial incentives. Platforms that distribute podcasts don’t necessarily receive a share of the ad revenue those podcasts generate. Meanwhile, producers benefit from broad distribution without necessarily compensating the companies making it possible.
As Page explains, the conventional economics of media distribution don’t always apply.
The industry is now experimenting with video, subscriptions, live events, licensing, exclusive content and other revenue sources. YouTube has emerged as a major podcast destination, blurring the distinction between audio programming and television. See another blog story of mine, Laptop is the New TV (2018).
Perhaps podcasting will eventually become another branch of the entertainment industry, dominated by a relatively small number of powerful companies, the way other media evolved.
Or perhaps podcasting’s sprawling, decentralized character will remain its defining feature.
I hope it’s the latter. That makes podcasts more fun. You never know what you’re gonna get.
Still in Praise of the Podcast
In 2013, I said there was a podcast on every topic. It’s even more true today. I can listen to an intelligent discussion of economics, an analysis of a soccer match, a conversation about classical music, or a lecture about an obscure episode in history, all on demand, usually free, and often with no more effort than tapping my phone.
Podcasting has enriched my life for 20 years. I have learned an extraordinary amount from people I otherwise would never have encountered. Successful podcasters, by and large, are very smart people with endless knowledge and wisdom to share.
And the beauty of the medium is that I choose what to hear, when to hear it and how much time to give it. That’s powerful.
For content creators, podcasting offers unprecedented access to audiences. For advertisers, it offers potentially intimate connections with carefully defined groups of consumers. For listeners, it offers a virtually inexhaustible library of information and entertainment.
But despite its explosive growth, podcasting remains an oddly immature business. It has yet to solve fundamental questions about measurement, discoverability, profitability and the relationship between creators and distributors.
We have figured out how to produce and distribute more podcasts than anyone could possibly consume. We haven’t figured out how to make the economics work for most of the people producing them.
Perhaps the next great breakthrough won’t be a new podcasting technology, superstar host or distribution platform.
Perhaps it will be developing a better way to connect valuable content with the people who want it, and rewarding the people who create that content.
Twenty years after I bought that little iPod Nano, I’m still listening. And I’m still fascinated by where this medium is headed.

The numerical estimates and industry observations in this draft are attributed primarily to the October 9 Freakonomics Radio episode and its published transcript, rather than treated as independently audited figures.
A Note About This Article: In 2013, I wrote about how a relatively new technology called podcasting was changing the way we consume information. Thirteen years later, I used another transformative technology, artificial intelligence, to revisit the subject. I provided ChatGPT with my original article, the recent Freakonomics Radio episode, and my observations about the evolution of podcasting. ChatGPT drafted this article, which I reviewed and edited before publication. The experiences, opinions and editorial direction are mine; much of the writing was generated by AI.
