What is a podcast? 

Maybe you’ve been living under a rock. Or maybe you want to learn all about your favorite hobby. Either way, if you’ve ever wondered what a podcast is and how it works, this article is for you. 

Below, we’ll cover everything you need to know about podcasts: what they are, who they’re for, and examples of the different popular podcast formats. Then, we’ll answer several frequently asked questions about 2023’s favorite audio medium.

What Is a Podcast?

A podcast is the streaming age’s answer to radio. The dictionary definition of a podcast is a digital audio file you can download or listen to over the Internet. Its interesting history explains why it is called a podcast, to begin with. 

Podcasts are a form of media content that was developed in 2004, when former MTV video jockey Adam Curry and software developer Dave Winer coded the “iPodder.” The iPodder was a program that let a user download internet radio broadcasts to their Apple iPod. This is where the term and meaning podcast was born, taking its name from a blend of ‘iPod’ and ‘broadcasts’. 

Today, podcasts are an extremely popular form of audio entertainment and have progressed beyond being downloadable radio shows. Each podcast is a series created by a host and then published episode-by-episode online, where subscribers can then download and listen to each episode when it’s released.

Unlike traditional methods of content production like TV and radio shows, podcasts are an accessible way for content creators to connect with an audience. They’re not even currently regulated, meaning you don’t need a broadcasting license to publish podcast content. Anyone with basic podcast equipment like a microphone, recording software, and a membership to a hosting platform can create their own show.

Monetizing a podcast is also becoming a reliable way to make either a side or a full-time income, thanks to brand sponsorships, affiliate marketing, subscriptions, and paid content.

Are Podcasts Audio or Video?

Podcasts started out as a completely audio medium. However, with the growing popularity of podcasts, many podcasters have embraced video podcasting as a way to stand out and reach an even bigger audience. 

Video is extremely popular—in fact, users are averaging 19 hours per week watching online videos in 2022 which is almost 50% more from 2018. So podcast creators who want their show to see the most growth and appeal to wider audiences are adding video elements to their podcasts.

What Is the Purpose of a Podcast?

A podcast can have many purposes, but the main one is to entertain its audience. Podcast listeners might have one of several reasons to subscribe to a podcast, such as to:

  • Hear updates and breakdowns of current events.
  • Learn about a new topic or industry.
  • Laugh at cohosts’ riffing and jokes.
  • Listen in on interviews with popular or famous guests.
  • Experience an audio drama or narrative storytelling. 

But behind each of these reasons is the desire to be entertained. Whether listeners want to learn something new or simply have something to take their minds off of a mundane task, they want to enjoy the experience of listening to a podcast. 

If they don’t enjoy it, they probably wouldn’t keep coming back.

Different Types of Podcasts with Examples

Podcasts are as varied as people’s imaginations can make them, and there are about as many genres as you can think of; news and education, health and fitness, comedy, and even fiction podcasts are just a few of the most popular kinds. 

While the podcasting world is wide and varying—and limited only by creators’ imaginations—the vast majority of podcasts can be broken down into one of four formats: 

  • Conversational
  •  Narrative nonfiction
  • Scripted fiction
  • Repurposed content. 

Of course, these are loose categories, and some podcasts are mixes or hybrids of multiple formats. We’ll take a closer look at each main category, along with popular examples, below.

There are also many genres of podcasts within these formats. According to Statista, the most popular podcast genres in October 2021 were comedy, news, true crime, and sports.

Conversational Podcasts

The most common podcast format is the conversational one. These are generally the most informal style, with anywhere from solo hosts to a roundtable discussion. Many of these shows are interview podcasts, which are discussions between one or more hosts and their guests, usually diving deep into the guests’ personal history or expert knowledge on a topic.

Stuff You Should Know is a very popular example of a conversational podcast. Hosts Chuck and Josh spend each episode educating each other (and the audience) about a topic of general interest. Their style is extremely informal, and listening to SYSK feels like listening in on a chill conversation between two friends.

The NPR Politics Podcast is made up of a roundtable of National Public Radio journalists. They discuss daily developments in U.S. politics with a friendly efficiency in episodes about 15 minutes long.

Another show from NPR, Guy Raz’s How I Built This, is an extremely popular example of an interview podcast. Raz’s guests are all the founders of some of the U.S.’s best-known and successful companies to learn their secrets to success.

Narrative Nonfiction 

Another structure that fits podcasting well is long-form storytelling. Narrative nonfiction covers anything that covers a true event or topic in a narrative style. 

These podcasts run the gambit from lyrical, topic-based human stories like This American Life, to deep dives into obscure mysteries like Wind of Change, to the ever-popular true-crime podcast like S-Town.

Scripted Fiction

When most people think of fictional entertainment, they think of TV or movies—but scripted podcasts are growing in popularity as well. 

Just as the episodic nature of podcasts works well for long-form nonfiction storytelling, fiction also does well in podcast form. Subscribers can tune in each week for a new installment of anything from experimental sci-fi fantasies like Girl in Space to historical fiction comedies like Edith!

Repurposed Content

Many content creators, from brands to bloggers to TV shows, repackage their content into podcasts. Listeners can catch highlights from their favorite late-night comedy central program on The Daily Show With Trevor Noah: Ears Edition

Or those who like to learn can tune into TED Talks Daily, which compiles TED Talks from around the globe into an easily digestible podcast for the commute.

How Podcasts Work and How to Listen to Podcasts

For podcasters, the process of creating and publishing a podcast is relatively easy. Once they’ve recorded and edited a few episodes, they need to upload them to their podcast host of choice. 

Want to try create your own podcast? Start recording with Riverside, a dedicated platform for professional podcasting. You can go to for more information, or if you’re ready sign up!

Then, podcasters submit their show’s RSS feed to podcast directories like Spotify, Apple Podcasts, or Stitcher. These directories are the place where podcasts and listeners connect; users can find, subscribe to, and listen to podcasts using their favorite podcast directory.

If you want to listen to podcasts, you’ll need to choose a directory first. There are many options available, but some of the most popular include:

  • Apple Podcasts
  • Google Podcasts
  • Spotify
  • Stitcher
  • Overcast
  • Podcast Addict

Some podcast directories have advanced customization functions, like multiple playlists, sleep timers, smart playlists, and suggestions for new shows based on your interests.

Whichever directory you choose, start by downloading the app from the Apple App Store or Google Play. Use the app’s search function to look for shows you might be interested in. You can listen to a single episode immediately, download it for later, or subscribe to shows so that each new episode is added to your playlist.

Now you’re ready to listen! Which show will you try first?
