Streaming Audio and Video Are Converging — And Creating New Inventory Opportunities
For years, audio and video were treated as separate media channels, each with its own publisher teams, advertiser workflows, and measurement frameworks.
Today, the boundaries between the channels are becoming much harder to define. A podcast listener, for instance, could very well discover a creator on YouTube, watch clips on social media, listen to a full episode during a commute, and encounter related content on a streaming platform later that same week.
Major media companies have responded in turn. For their part, Netflix and Paramount are investing in podcast and creator-led formats, while YouTube has become one of the largest podcast platforms in the world. At the same time, streaming audio platforms continue to expand into video and interactive experiences.
For publishers, these shifts have also sparked important opportunities. Notably, as audiences move more fluidly between listening and viewing, inventory can increasingly be packaged around content, context, and audience behavior rather than format alone.
How audience behavior is blurring audio and video
Take video podcasts. While often described as a new format, they are more than anything a reflection of a broader change in how audiences consume media.
Specifically, people increasingly track their interests through creators and communities rather than on any individual platform. For example, a sports fan might watch highlights on CTV, listen to a podcast recap the next morning, then engage with YouTube clips and shorts throughout the week. In short, the audience relationship remains largely unchanged even as the format evolves.
What’s more is that audio and video increasingly work together by extending the amount of time audiences spend with content and the creators behind it. For publishers, that means inventory opportunities are no longer confined to a single environment as content can travel further, reach audiences in different contexts, and create more touchpoints for monetization.
Why this moment resembles CTV's own inflection point
Connected TV offers a useful comparison here. CTV did not become a major advertising channel simply because consumers started streaming television. In fact, streaming behavior existed long before advertisers fully embraced the medium. The inflection point came later, when infrastructure made fragmented inventory easier to buy, measure, and scale. That led infrastructure to mature, giving advertisers confidence they could buy, measure, and optimize the channel at scale.
Audio and video are approaching a similar moment. As podcasts become video content and streaming platforms embrace creator-led media, buyers are thinking less about individual formats than they are about audience access. Publishers that can package inventory across listening and viewing environments may be better positioned to participate in those conversations.
The sell-side opportunity therefore extends beyond a podcast impression or a video impression. Increasingly, it involves helping advertisers reach audiences across a broader content ecosystem.
Where new inventory opportunities are emerging
The dynamics that are bringing audio and video together are also creating inventory opportunities that did not previously exist. Historically, publishers often sold podcast inventory, streaming audio inventory, video inventory, and connected TV inventory through separate processes.
Audience behavior increasingly cuts across those categories. Creators, audiences, and advertisers increasingly operate across multiple environments. This means that the publishers that connect those experiences can create more valuable inventory packages.
For instance, a sports publisher might combine podcast audiences, video recaps, and connected TV programming around a major event. A business publisher might package creator content across multiple formats and environments. In cases like these, the underlying content already exists, but the opportunity lies in organizing, qualifying, and packaging it in new ways.
How Audion helps publishers monetize converged inventory
This convergence of streaming audio and video opens a new path to monetization. Rather than simply distributing content across formats, publishers today need better ways to understand what their content contains, how it can be qualified, and where it aligns with advertiser demand.
That is where Audion can help.
By analyzing audio and video content at scale across platforms such as YouTube, Spotify, Apple Podcasts, and Amazon Music, Audion helps publishers surface valuable contextual signals, identify advertiser-relevant environments, and make more of their inventory discoverable to buyers. Every month, Audion AI analyzes the equivalent of more than 100 years of newly published audio and video content, helping turn large content libraries into structured, actionable opportunities.
As listening and viewing continue to converge, publishers need a common intelligence layer capable of understanding both. Audion provides exactly that layer, helping publishers unlock more value from existing content while making inventory easier for advertisers to evaluate and activate.
For publishers looking to monetize audio and video together, the opportunity starts with understanding the content they already own.
