8 Types Of Podcasts And How To Choose Yours

Audio isn’t niche anymore.

Around 79% of people in the U.S. listen to digital audio every month , and podcast consumption continues to hit record highs year after year.

That shift in public content consumption changes corporate content expectations too. People aren’t setting aside time to consume corporate content. They’re fitting it into everything else: commutes, walks, gaps between meetings. Which means the content's format matter more than most people expect.

Not all podcasts land the same way. A long conversation might work for some audiences, but it's a bad fit for a 15-minute commute. A quick solo update might get played immediately. Something heavier gets saved for later.

That’s where most people get stuck: it's not a lack of ideas, but it's because they’re choosing audio formats that don’t match how their audience wants to listen.

For teams thinking about how to deliver internal communication more intentionally, internal podcasts can now play in the apps employees already use, leveraging the listening habit that already exists.

With that technology, the real question for leaders isn’t just should we create something, but which format will deliver best for the team.

8 Types Of Podcast Formats (And What They’re Used For)

There are many types of podcasts, but most teams rely on a small set of formats. So, how many types of podcasts are commonly used by companies today? Usually, eight core formats cover most use cases.

That choice shapes everything: how your podcast sounds, how easy it is to produce, and whether listeners stick around. Most people start with topics. That’s where things go wrong. A podcast about a specific topic can work in multiple formats, but not every format fits how people actually listen.

Here are the main types of podcasts and what each one is used for:

1. Solo Podcasts

A solo podcast is exactly what it sounds like: a single host delivering content in a structured, usually monologue-style format.

This format works well for deep dives, updates, or educational content where clarity matters more than conversation. It’s also the easiest way to start, since there’s no dependency on guests or co-hosts.

Because of that simplicity, solo formats are widely used across many types of podcasts. In a business setting, they’re especially effective for internal communication—like leadership updates, training, or company announcements—where the goal is to deliver a clear, focused message without unnecessary back-and-forth.

The upside is control. You decide the pace, tone, and direction. The downside is just as clear: if the delivery falls flat, the entire episode can feel long very quickly. Monologue formats don’t hide weak content, so keep it short and focused on the topic.

2. Interview Podcasts

The interview podcast format is one of the most popular podcast formats for a reason. It brings in fresh perspectives without requiring the podcast host to carry everything alone.

Interview podcasts work well when they focus on a specific topic or expertise. Instead of explaining everything yourself, you let someone else do the heavy lifting. That’s why this is a common podcast format across many podcast genres.

The challenge, however, is consistency. Booking guests, prepping questions, and keeping the conversation tight takes more work than it looks.

3. Co-Hosted Podcasts

A co-hosted podcast adds a second voice, which immediately makes the podcast feel more conversational. That’s why conversational podcasts are among the most popular types of podcasts today.

This format works well when you want energy, reactions, and a more natural flow. Podcasts often feel easier to listen to when it sounds like a real conversation, not a scripted audio recording.

The catch is chemistry. If it’s off, listeners notice fast. If it works, you don’t need much else.

4. Roundtable Podcasts

Roundtable podcasts bring in multiple voices. Think discussions, debates, or unpacking a different topic from different angles.

This is one of those podcast styles that sounds great in theory. In practice, it needs structure. Without a strong podcast host guiding the conversation, it turns into people talking over each other.

When done right, it’s one of the most engaging formats. You get real-world examples, multiple perspectives, and a sense of depth that a single voice can’t create.

5. Narrative And Documentary Podcasts

This is where storytelling podcasts stand out. Narrative formats focus on storytelling, not just information.

These include styles like investigative podcasts, true crime podcasts, and long-form podcast series built around a single arc. They rely on scripting, editing, and strong podcast audio production.

This format takes the most effort, but it’s also among the most popular podcast genre categories because it holds attention. People don’t just listen to podcasts like this; they binge them.

6. Educational And Training Podcasts

Educational podcasts focus on teaching. Clear structure, clear takeaways, and repeatable content.

These formats work well when used for onboarding, training, or skill-building in internal communication. Educational podcasts focus on teaching in a way that can be revisited, which makes them useful over time.

They’re not flashy. But they’re effective. And in most cases, that’s the point.

7. AI Summary podcasts

We’re turning to AI more and more to help work through huge amounts of data and content to find the insights. Whether it’s an audio rundown of industry trends, the day’s news, or several whitepapers, AI can both pull out the insights and produce high quality audio.

Companies can use AI podcasts internally when transparency or information overload is creeping in. Several AI podcasting tools allow you to take something as dense as product release documentation and create a quick, compelling conversation about it.

The best part for under-resourced production teams? These episodes can compliment your work without significant additional effort.

8. Fiction And Scripted Podcasts

Fiction podcasts and fictional podcasts are fully produced experiences. Scripts, voice actors, sound design. This is podcasting at its most immersive.

This format isn’t common for internal podcasters, but it shows what’s possible with audio content. Podcasts can create atmosphere, tension, and emotion in a way few other formats can.

Even if you don’t make podcasts in this style, there’s a lot to learn from how they handle pacing and storytelling.

At this point, the format you choose matters more than the type of podcast you think you’re making. There are many types of podcasts, but it's up to you to match the format to how your audience listens. Choosing the right format early makes everything else easier.

How Do Different Podcast Formats Serve Different Goals?

With the formats clear, what matters next is how they actually get used. Most podcasts don’t fail because the idea is weak. They fail because the format doesn’t match the job.

A podcast built for storytelling won’t work for quick updates. A conversational podcast won’t always land when clarity matters. The format has to do the heavy lifting.

Formats For Business Communication

Which types of podcasts work best for business communications? That depends on your goal.

If sharing an internal update, a solo podcast format could work best. It’s quick, clear, and doesn’t need coordination. Think of this like a news show - add some personality and avoid sounding overly scripted.

If the goal is to hear multiple perspectives, that’s where interview or co-hosted formats come in. They give context without turning a simple update into a 30-minute monologue.

The mistake most teams make is over-formatting something simple. Not everything needs a conversation. Sometimes it just needs to be said once, clearly.

Formats For Storytelling

What types of podcasts are best for storytelling and education? Narrative formats are built for this.

When the goal is to hold attention over time, structure matters more than anything else. Storytelling podcasts work because they create progression. One idea leads to the next. There’s a reason to keep listening.

This is why formats like investigative or true crime podcasts are so effective. They’re designed to pull people through the content, not just present it.

They also take the most effort. Which is why most teams like the idea… until they see the work involved.

Formats For Learning And Training

For learning, people aren’t only listening for entertainment; they’re trying to understand something and come back to it later.

That’s where simpler formats win: a structured solo podcast or a lesson-based podcast series makes it easier to follow, pause, and revisit. A more advanced approach for internal educational content blends the clarity of an announcement with the emotional power of interviews.

Want to educate the team on a new product? Intro the product, but include an interview with a customer that is already benefiting from the change. Your team will both get the update, and feel connection to improving the customer experience.

Formats For Engagement And Conversation

When the goal is engagement, conversation starts to matter more.

Co-hosted and roundtable formats work here because they feel natural. People are more likely to stick with something that sounds like a real discussion than something that feels overly scripted.

That said, “natural” doesn’t mean chaotic. Without structure, these formats drift fast, and this is where co-host or interviewer/interviewee chemistry matters. Make sure that all parties are “warmed up” before diving right into recording.

With your style selected, don’t overlook your delivery and distribution choices. When content needs to reach specific audiences without getting lost in everything else, distribution matters just as much as format.

That’s where private podcast platforms make it easier for companies to reach the right internal audiences without changing how employees already listen.

How Do Podcast Formats Fit Into Real Listening Habits?

Podcast formats make sense on paper, but your strategy matters much less than your audience preferences.

Most podcast listening happens in between things: walking, commuting, or in the background of work tasks - the more you know about listening habits, the more you can tailor your content to be a perfect fit.

Short-Form And Conversational Formats For Daily Listening

People rarely have long, uninterrupted time. They dip in and out.

For commuting and travel, shorter formats like daily updates, solo podcasts, or conversational podcasts tend to work best because they fit into limited time and don’t require full attention. A focused solo podcast or a quick conversational podcast gets the point across in under 20 minutes.

Long episodes still work, but a 60-minute podcast episode when employees have a 15-minute commute usually means “I’ll finish this later,” which might mean “never.”

Structured Formats For Learning And Retention

When someone hits play to learn, the expectation changes. They want clarity, not noise.

For learning and self-improvement, educational podcasts and expert-led interview podcasts are the most popular since they’re easier to follow, revisit, and apply over time. A structured podcast format with clear segments makes it easier to pause, come back, and pick up where you left off.

Educational podcasts focus on teaching. If the structure is loose, the content gets harder to use, so be sure you’re clear about each episode’s outcome to earn your learners’ time.

Formats That Continue To Perform Consistently

Some formats just hold up over time.

Right now, interview and conversational podcasts remain some of the most widely used formats for popular public podcasts, along with narrative-style shows built around deeper storytelling.

You and your team will need to decide what style is realistic for both your audience and your resources.

How to Choose a Podcast Format You Can Sustain

Podcast listening isn’t evenly distributed. Around two-thirds of adults under 30 have listened to a podcast in the past year , compared to just 28% of those 65 and older.

That gap shows up in how people consume podcasts and how often they come back.

By now, you’ve seen the types of podcasts and where each format fits. What matters here is simpler. Can you keep it going? Some formats feel easy until they aren’t. A few episodes in, things pile up. Scheduling, recording, and editing add up fast.

Choosing the right podcast format comes down to one thing. What fits your audience and your ability to show up consistently?

Start with Your Audience

Before picking a format, look at how people already listen to podcasts. Short bursts, partial attention, switching between apps.

A podcast built for deep dives won’t land the same way as one built for quick updates. If your audience is listening during a commute or between tasks, the format needs to respect that. Otherwise, even good audio content gets skipped.

Match the Format to Your Resources

Some podcast formats look great until you try to make them every week.

Interview podcasts need guests. Narrative formats need editing. Even a simple solo podcast needs planning and clean audio recording.

Podcasting works best when the format fits your time, your team, and how often you can realistically publish. If it feels heavy to produce, it won’t last long. Don’t be scared to add AI episodes if they keep your publishing cadence on track. Tell your audience that the voices are synthetic, but don’t be surprised when the team asks to have “the robots” summarize more on your behalf.

Choose a Format You Can Stay Consistent With

Consistency beats creativity most of the time. A clear, repeatable podcast format makes it easier to build habits for both podcasters and listeners.

This is also where distribution starts to matter. If people have to jump through steps to listen to podcasts, they won’t. Supporting Cast makes it easier to deliver internal audio updates through apps like Spotify or Apple Podcasts, so the employee experience stays simple while access stays controlled.

The easier it is to publish and listen, the more likely the podcast actually sticks.

How to choose the Podcast Format That Actually Works For You?

The difference between a successful pod and a flop comes down to fit. Fit with your audience, your time, and how podcast listeners actually listen.

Some formats look great until you try to run them every week. Others feel too simple, but they end up being the ones that quietly build momentum. The right podcast format makes recording easier, publishing more consistent, and podcast listening adoption smoother.

You don’t need the most creative setup; you need the one that meets your audience where they are and doesn’t overburden the creators.

That’s where Supporting Cast can help. It handles secure delivery, access control, and listener-level analytics so your internal audio content fits into apps employees already use, without extra steps or friction.

If you’re looking to make podcasting easier for both your creators and your listeners, it’s worth scheduling a demo and seeing how it works.
