The odds are stacked against this podcast advertising pioneer

I admire what Podbridge is attempting to do. They seem to have taken the lead in monetizing podcasts. I doubt they will succeed, though, unless other conditions change and change fast. Podbridge has created a podcasting advertising network, one that promises to match audio ads to podcasts that you download via iTunes (and, eventually, elsewhere).

Ads would be fed to you randomly along with podcast content. The ads, which would be dynamically stitched onto the podcasts, are served up based on your age, gender and location (such as ZIP code). Nice idea, but …

My skepticism has to do with whether people will volunteer this information (age, gender, location) to receive something that they are currently accustomed to receiving for free, and mostly free of ads.

Much more logical (but logistically challenging) is to follow the ad model that Podbridge claims to be mimicking — that of magazine advertising.

In this alternative, each major podcast producer would receive ad insertions and interweave those ads with their content. This wouldn’t provide the flexibility and customization of regional-, age- and gender-based targeting, but it would talk to people based on their enthusiasms. For instance, DVD rental ads would be placed on podcasts such as Filmspotting (as they are now, for PeerFlix).

These ads could still include Pay-Per-Call ads supported by Ingenio, as Podbridge is currently planning. It’s a brilliant use of this phone-based ad concept, which was first introduced and tested in limited Yahoo sponsored listings.

This alternate business model also allows for the strength of product placement, something that started with the early days of radio and television, and has found a new life as a way for advertisers to get their products in front of viewers who use DVRs to blaze past television progamming’s commercials.

True, this lack of scalability makes it a less-profitable business model, since podcasts are typically today such a Long Tail phenomenon.

But the dearth of consumers willing to opt-in to receive ads makes the Podbridge concept fatally flawed in my opinion. At least until there is a critical mass of premium content podcasters who will only distribute their product with Podbridge-provided advertising. That day is a long way off.
