What is a podcast and how does it work? On the surface, that sounds like an entry-level question. For a B2B marketer evaluating whether to invest in the format, it is also the most strategic question you can ask. The mechanics of podcast distribution determine why the format reaches buyers in contexts no other channel can, and why 67% of B2B marketers plan to launch a show in 2026, up from 42% in 2024.
This guide answers what is a podcast and how does it work, from the technical plumbing to the business case, so you can make a confident decision about whether the format belongs in your marketing mix.
A podcast is an on-demand series of audio or video episodes, published to a hosting platform and distributed via RSS feed to every major listening app simultaneously. Subscribers receive new episodes automatically on whatever device they prefer, whenever they choose to listen.
Three characteristics define the format and separate it from everything else:
The RSS piece is the part most marketers skip over, and it matters more than any other technical detail. Because of RSS, uploading one episode to your hosting platform puts it inside Spotify, Apple Podcasts, and a dozen other directories within minutes, without any manual action on your part. Your content appears in apps your buyers already trust and open daily.
For a deeper look at the strategic meaning behind the format, what does podcast mean covers the definition from both a technical and business perspective.
The word is a portmanteau of two things: iPod and broadcast.
British journalist Ben Hammersley coined the term in a February 2004 Guardian article. By his own account, he was padding a short piece about the emerging practice of distributing audio online and simply listed "podcasting" as one possible naming option. He did not expect it to stick. It did.
"Podcast" was named the Word of the Year by the New Oxford American Dictionary in 2005, less than two years after it was invented. The iPod association is now outdated: you do not need an iPod, or any Apple product, to listen to a podcast. The "broadcast" part still holds. The format is about distributing episodic content to an audience at scale, digitally, on demand.
Listeners have three ways to access podcast content:
Stream directly. Open Spotify, Apple Podcasts, or any podcast app, find a show, and play an episode. No download, no subscription required. This is how most casual listeners sample new shows.
Download for offline listening. Most apps let you save an episode to your device for playback without a connection. Useful for commutes, flights, or any context where data is limited.
Follow or subscribe. Following a show in a podcast app tells the app to watch the show's RSS feed and automatically surface new episodes as they publish. This is the default behavior for regular listeners. Note: "subscribe" has been largely replaced by "follow" in modern apps, though the behavior is identical.
That third option is what makes podcasting structurally different from other content channels. A follower does not need to remember to check your website, open a push notification, or click through an email. The new episode appears in the app they already open for other shows. You are present in the environment your audience chose for this format.
The publishing chain has five steps:
That five-step chain means the operational overhead of distribution after launch is near zero. The work is in production, not in publishing logistics.
The distinction between audio and video podcasting is not simply whether a camera was present. It is a question of design intent.
Audio-only podcasts are built for passive, distracted consumption. The listener is doing something else: driving, exercising, cooking, walking. The audio carries the entire experience. Distribution happens through podcast directories. This format reaches people in contexts where no screen-based content can.
Video podcasts are built to be watched. They include camera angles, lighting, set design, and visual editing. Distribution is primarily on YouTube, with clips repurposed as Shorts and Reels across social platforms. The visual layer creates additional repurposing opportunities and allows the show to capture YouTube's search traffic alongside traditional podcast directories.
Video has become the professional default for B2B podcast production in 2025. The reason is not that audio is less valuable; it is that video produces more repurposable content per recording session. A single interview produces the full episode, a YouTube video, multiple short clips, and thumbnail stills, all from the same recording.
Many B2B shows publish both: a full video on YouTube and an audio-only version distributed through podcast directories. This approach maximizes reach without requiring separate recording sessions.
The audience data makes the business case straightforward: 75% of B2B decision-makers listen to podcasts, and 51% listen daily. Your buyers are already in the habit. The question is whether your brand is part of it.
Beyond the audience size, the format has structural advantages that no other B2B content channel replicates:
Depth of engagement. The average podcast episode earns 20 to 40 minutes of uninterrupted attention per listener. A LinkedIn post earns seconds. That difference compounds over a series of episodes into genuine brand familiarity and trust.
Guest-to-client pipeline. Inviting a prospect to be a guest on your podcast is a low-friction relationship entry point that traditional sales outreach cannot match. The average guest-to-client conversion rate on B2B podcasts is 10%, with top-performing shows reaching 48%.
Repurposability. A single 45-minute interview produces the episode itself, a blog post, a newsletter section, multiple short-form video clips, and pull quotes for social. The production investment scales across formats.
Evergreen search value. Podcast episodes are indexed and searchable. A well-produced episode on a specific B2B topic continues to surface in search results long after it publishes.
Proven results. 76% of B2B companies launch podcasts specifically for thought leadership. 90% of companies that invest in a branded podcast report being satisfied with the results.
The format is not experimental at this point. It is a documented content marketing channel with measurable returns, and how to launch a company podcast walks through the full process of building one.
You now know what a podcast is and how it works: a series of on-demand episodes distributed via RSS to every major listening app, reaching your buyers in the contexts where no other content format can follow them.
The format has a 20-year track record, a mature infrastructure, and a B2B audience that is already listening. The operational overhead after launch is low. The returns, for companies that build shows with a clear strategy, are well-documented.
