Most podcasts are just for listening. But many people now make video podcasts too. In 2025, a billion people watched podcasts on YouTube every month.

The word "podcast" has a very interesting history. It is a portmanteau, which is a word made by joining two others. It combines "iPod" and "broadcast" to create a new name. The term was first used by journalist Ben Hammersley in early 2004. Later, Danny Gregoire and Adam Curry helped the name spread. Even though it mentions the iPod, you can use any computer.
Podcasting has grown into a massive industry over the years. In 2004, Adam Curry launched his show called Daily Source Code. Later, The Ricky Gervais Show became a huge hit with many downloads. By 2007, podcasts were doing what radio had done for decades. In early 2019, Edison Research estimated 90 million people in the U.S. listened to podcasts. There are now over three million different podcasts available to listeners.
Podcasts are easy for anyone to start making. You only need a microphone, a computer, and some software. Many people listen while they are commuting in cars or trains. Because they are often free, they are called a disruptive medium. This means they change how we think about traditional radio. Some creators also use crowdfunding to get help from their fans.

While podcasts are primarily an audio medium, they have expanded significantly in recent years. Many creators now produce video podcasts, which may appear as primary content or as supplements to audio. In 2025, Bloomberg reported that one billion people watch podcasts on the YouTube video platform every month. This shift to video can sometimes create challenges for audio-only listeners. If a host shows something on screen, an audio listener might miss that important context. Podcasts can cover a vast range of topics, from scientific research to slice-of-life journalism. They can be carefully scripted or completely improvised by the hosts.
The technical process of podcasting involves several specific steps to move files from a creator to a listener. First, a podcaster prepares audio or video files using a computer and a microphone. They then upload these files to a podcast hosting company, such as Libsyn or SoundCloud. These hosting companies use RSS feeds, which are web feeds that maintain a central list of files on a server. The hosting company distributes these files to various podcast directories and streaming services. These services include platforms like Apple, Spotify, and YouTube.
Listeners use a podcast client, which is special application software on a computer or mobile device. This client accesses the web feed and checks for updates. When it finds a new episode, it downloads the file or streams it directly. This automation can make it feel as though the podcaster is "pushing" the show to the user.
Podcasts vary greatly in their format and how they are funded. Some shows are entirely free to download, which is why podcasting is often called a disruptive medium. This term refers to how podcasting challenges traditional revenue models used by older media. To make money, many podcasters use different business models. Some are underwritten by corporations or include commercial advertisements. Others use a paid subscription model or sell products directly to their audience. Some creators even use crowdfunding websites like Patreon to receive support from their community. This allows them to provide special extra content to fans who pay a fee.
The name "podcast" has a unique origin as a portmanteau. This means it is a word created by joining two other words together. It combines "iPod," a famous music player, and "broadcast," which refers to transmitting content. The term was first used by journalist Ben Hammersley in early February 2004. Later, the term entered the audioblogging community when Danny Gregoire used it in a mailing list. It was then adopted by Adam Curry, who became a key figure in the early community.
Even though the name includes "iPod," you can actually listen to podcasts on any device that plays media files.
The history of podcasting is filled with important milestones and technological shifts. In September 2000, a service called MyAudio2Go.com allowed users to download news stories to MP3 players. In October 2000, Tristan Louis proposed attaching sound and video files to RSS feeds. This idea was later implemented by software developer Dave Winer. In August 2004, Adam Curry launched his show, Daily Source Code. This show helped build a community of pioneer podcasters. By June 2005, Apple added formal support for podcasts to iTunes 4.9. This was a major change because it removed the need for separate programs to transfer files to mobile devices.
Podcasting has seen massive growth in popularity and commercial success. For example, The Ricky Gervais Show became one of the most successful podcasts in history. By March 2011, it had gained more than 300 million unique downloads. While the Adam Carolla Show set a Guinness world record with nearly 60 million downloads, it had significantly fewer downloads than the Gervais show. By 2007, audio podcasts were performing the same roles that radio broadcasts had held since the 1930s. The industry has grown to include over three million podcasts and nearly 200 million episodes. In early 2019, Edison Research estimated that 90 million people in the United States were listening to podcasts.
Podcasting is considered a converged medium because it brings together audio, the web, and portable media players. It has changed how public figures interact with the world. The New York Times reported in 2025 that podcasts are now an alternative to magazine covers or late-night talk shows. The intimate setting of a podcast allows guests to be more candid and open.
This medium is also very accessible for new creators. It requires very little overhead to start. A person only needs a microphone, a computer, and software to edit and upload their work. This low barrier to entry has allowed a massive variety of voices to join the digital landscape.
