The origins of podcasting

With some of the most popular podcasts garnering millions of podcast subscribers (the Joe Rogan Experience gets over 11 million listeners per episode), the world of podcasting is clearly pretty popular. But it didn’t start out that way.

When did podcasts start?

Before podcasts were invented at the turn of the 21st century, people had already been experimenting with video blogs and internet radio shows. But in 2003, software engineer Dave Winer developed an audio RSS feed for former The New York Times reporter and public radio host Christopher Lydon, who used this new RSS feed to offer audio content of notable interviews on his blog. 

Tapes of Lydon’s interviews made their way through BloggerCon in 2003. In 2004, Winer partnered up with former MTV VJ Adam Curry and created iPodder, a program that allowed people to download internet radio broadcasts and other audio content to their iPods. These broadcasts were soon called podcasts, named after the iPod MP3 player that played them.

By the end of 2004, the very first podcast hosting platform Libsyn (short for Liberated Syndication), came to life.

In 2005, Steve Jobs built podcast subscriptions into iTunes (now known as Apple Podcasts). At that point, podcasts stopped being a niche hobby for tech enthusiasts and started their path toward the mainstream.

When did podcasts become popular?

Although podcasts steadily gained popularity since 2004, one can make a case that podcasts didn’t really take off until the holy grail of true crime podcasts was launched: Serial. The podcast was the first show to reach five million unique downloads on iTunes. The total number of monthly podcast listeners in America went from 40 million in 2014 to 88 million five years later.

What was the first podcast?

Technically, Radio Open Source by Christopher Lydon was the first podcast, launched in 2003. However, the term “podcast” wasn’t coined yet. That term was coined by Guardian columnist Ben Hammersley and pioneered by Curry.

After iPodder was created, Curry made the first true podcast, The Daily Source Code, which was all about podcasting. It featured insights on Curry’s everyday life and events in the podcasting space, covered general news, and played music from the Podsafe Music Network.

The rise of podcasts’ popularity

The beauty of podcasts is that there’s a show for just about every topic. Listeners can find podcasts for almost every niche passion or interest—like the Denzel Washington Is The Greatest Actor Of All Time Period comedy podcast, which simply goes through Denzel Washington’s filmography in alphabetical order. Or Shezam, a podcast for female magicians. 

And with the rise in popularity comes the rise in advertising dollars. Today, creators are able to monetize their podcasts with podcast ads and affiliate marketing. This has resulted in podcasts with higher production value—and incentive for more people to create new podcasts.

Podcasting in recent years

Podcast statistics show that 41% of Americans have listened to a podcast in the past month, and the podcast advertising market worldwide is expected to reach $3.46 billion in 2023. Those numbers show that podcasting has become a medium lots of brands are using to reach a diverse audience.

The future of podcasting

The number of podcast listeners is expected to reach 254.35 million by 2024. And according to Forbes, “private podcasting” may be the trend, leading to smaller, more intimate shows that are only available to those with a private invite.

Video podcasts are becoming increasingly popular, thanks to YouTube adding support for podcast playlists and, soon, RSS. In fact, YouTube is now the number one source for podcast discovery. Podcasters are increasingly adding video content to their audio-only shows.

Along with that, artificial intelligence (AI) is becoming more prevalent. Podcasts written and hosted entirely by generative AI now exist, for better or worse. High-profile podcasts like Believable: The Coco Berthmann Story are using custom AI voices as a stand-in for a character that couldn’t be interviewed. And thanks to tools like Descript, AI is being used by podcast creators in every stage of creating an episode — from pre-production to recording and editing.
