Most public radio stations have unsold digital inventory. The audience has real value; the trouble is that the buyers who’d pay for it and the stations who own it have never had a good way to reach each other.
American Public Media and StreamGuys built the Inform Media Network to close that gap. It connects national underwriters with public radio’s audiences and routes the revenue back to the stations that earned it.
Background
Before any of this went out to stations, APM and StreamGuys ran a deliberate test-and-learn process. The goal was never to bolt a commercial ad network onto public media and hope nobody noticed. It started from what public media stations and their audiences expect.
The proving ground was a pilot with real public media organizations. A large share of digital listening audience turned out to be out of market. These were loyal, engaged listeners tuning in from outside of the local market. For a local underwriter, those impressions were not reaching the target listener. At the same time, local inventory was regularly sold out weeks in advance.
National sales teams had the opposite problem: demand from national brands without enough inventory to fill it.
So you had a station leaving money on the table on both ends. The fix was a division of labor. The local station keeps selling locally while national sales teams sell the broader public radio audience at national scale. Neither party is cannibalizing the other.
That’s the whole idea. The rest of the program is built around it.
What Inform Media Network is
At its core, the Inform Media Network is a partnership between APM, StreamGuys, and you. The labor splits cleanly:
APM brings the national sales team, the booking, the creative production help, and all the ad operations.
StreamGuys handles the technical side — the plumbing, the configuration, answering your questions, and paying you.
For most stations, participating means saying yes and setting a few preferences. The program is built to be low-effort for stations: if the network creates work for your team, it’s failed.
There are three things the program does for a station, and depending on where your strengths and gaps are, one or all three might matter to you.
1. National sales on your unsold inventory. APM’s national team sells your unsold sponsorship impressions across live stream and podcast, pre-roll and mid-roll. This is real underwriting, sold by APM, and it sounds exactly like what already runs on your station. “This program is brought to you by.” No jingles, no calls to action, no commercial-radio energy.
2. Audience data you can use locally. Every participating station gets qualitative audience data from Magellan AI at no cost. Stations are encouraged to use it in their own local pitches. More on that below.
3. Access to Marketplace inventory in your DMA. This one lets your local team sell local sponsorships into APM’s national podcasts — including Marketplace — geotargeted to your market. It gives smaller podcast rosters a lot more to sell, and a marquee name to bring to underwriters.
Two of those are about helping you sell better. Only one is about filling your unsold inventory. That’s on purpose — a big part of the point here is leveling up local digital sales, not just backfilling unsold inventory.
And it’s free to join if you’re already running dynamic ad-insertion with StreamGuys. There’s no cost to add the network on top of it.
National Underwriting Sales
The mechanics run on a waterfall, and it’s the part that keeps the network from ever stepping on your own sales.
Your inventory fills in priority order: your direct sales first, then the Inform Media Network, then your own unsold house campaigns. Each tier only gets what the tier above it didn’t use. If you sell everything yourself in a given month, the network takes nothing. If you have a slow month and only sell half your inventory, the network bids on the rest and fills what it can. Anything left over drops through to your house spots — membership drives, event promos, whatever you’d normally run.
It slides into the middle of your stack with no conflict on your direct-sold campaigns. You keep doing exactly what you do today.
Rich Station Data
National buyers don’t just want a good audience anymore. They want data about that audience — who they are, what they buy, how they index against everyone else, how they respond to a message. That’s table stakes in a national negotiation now. “Public radio listeners are affluent and educated” is true, but it isn’t currency. Buyers want it proven.
The gap is that most stations have solid broadcast research and very little on the digital side. Downloads and impressions, maybe, but nothing on who the audience actually is or whether they convert.
That’s what the Magellan AI data fills in. Participating stations get regular insights that run well over a hundred data points, covering demographics, purchase intent, and behavioral indexing against the average American digital listener. Instead of saying your audience is affluent, you can show exactly where it overindexes.
It also carries weight because it’s third-party data, provided by Magellan. It’s not you making a claim about yourself. Your direct sales team can drop it into prospecting decks (with proper citations APM can supply) and carry it into category pitches and renewals.
Local Marketplace Sell-in
The Marketplace piece is still taking shape, but the concept is straightforward and a lot of stations lit up when they heard it.
As a member station, your local sales team can sell local sponsorships into APM’s national podcast inventory, delivered to listeners in your own DMA. So if you’re in San Antonio, you can sell against the audience listening to Marketplace on Apple Podcasts or Spotify inside the San Antonio market. It’s national-caliber, award-winning programming that your team sells to local advertisers, delivered right into your market. No impressions wasted.
For a station without much of a podcast roster, this is a real expansion of what you have to sell. You submit an online order form, and APM handles the ad ops, the creative production, and the reporting. You don’t produce anything new, add staff, or touch your ad load. A growing number of local markets are already running with it.
Public Media’s Authentic Sound
The Inform Media Network is not a commercial-radio programmatic network. You will not hear commercial radio ads in your stream.
APM reviews all the creative. Everything currently running is FCC-compliant, 15-second underwriting. FCC rules technically don’t govern digital, but APM errs on the side of caution across the whole network because it’s cleaner for everyone.
You also keep full control of what runs:
- Frequency caps are yours. Whatever you’ve set in your ad server sits on top of APM’s rules. If you cap listeners at one pre-roll every 30 minutes, that holds, and the network doesn’t override it.
- Category and advertiser blocks are yours. Don’t want automotive, or healthcare, or one specific competitor of a local client? Tell your StreamGuys contact and it’s filtered out. This can’t be overridden by the network.
- Competitive separation is handled at the technology level, so a network software sponsor won’t run adjacent to your local software client.
- Participating isn’t a blanket license. You’re granting rights to monetize the specific content you choose, not everything. You can also run custom streams: a pledge-drive stream with no pre-rolls at all, or one that carries your own spots but nothing from the network.
The Bottom Line
The Inform Media Network really comes down to a few things. It’s incremental revenue on inventory you weren’t selling anyway. It doesn’t change how your station sounds, and it doesn’t take local sales out of your hands. The audience data and added inventory also give your own team more to work with, which over time may be the part that matters most.
