Ad Infinitum S4E01: Two Circles | Dallas Taylor on Podcasting, YouTube, and Creative Identity

Season 4 · Episode 1

Saturday, March 7, 2026 • Duration 01:12:46

Ad Infinitum returns for Season 4, and for the first time, we’re on video.

To kick things off, I brought back the very first guest ever on the show: Dallas Taylor, host of Twenty Thousand Hertz, founder of Defacto Sound, and now creator of the fast-growing video channel DallasTaylor.mp3.

In this episode, Dallas shares the moment he almost quit podcasting entirely, and the simple insight that changed everything.

Two circles.

One for podcast audiences.
One for YouTube.

That realization led to a completely new way of thinking about media: podcasts, YouTube, TikTok, and Instagram working together as a discovery engine rather than competing formats.

Along the way we discuss:

• Why creators shouldn’t think of themselves as “podcasters” or “YouTubers”
• The psychology of creativity in the age of algorithms
• Why the audience sometimes comes last in the creative process
• How Dallas built a solo production workflow that unlocks impossible access
• Why vertical video and audio storytelling can coexist
• The difference between client work and self-expression

If you care about podcasting, creative work, or the future of media, this conversation is a masterclass in how the landscape is changing, and how creators can adapt without losing the craft.

Ad Infinitum is the podcast devoted to audio ads, the creatives who make them, the thinking behind them, and how to make them work better.

Hosted by Stew Redwine.

Ad Infinitum is Presented by Oxford Road and Produced by Angela Hunter, Caitlyn Spring, & Ezra Fox, written & hosted by Stew Redwine, and sound designed by John Mattaliano, with audio production by Zach Hahn.

Remember: have fun making the ads work.

The Ruler & The Regent | The Audio Monarchy | The history of radio predicts the future of podcasting and audio advertising.

Wednesday, January 28, 2026 • Duration 01:06:51

In the Season 3 Finale of Ad Infinitum, host Stew Redwine hands the mic to producer Jeanna Isham for a special editorial episode - no ad roundup, no scoring, no guest interview - just a wide-angle story about the history of audio advertising and why sound has always been the hidden power in advertising, regardless of how it shows up.

Jeanna frames audio history as a monarchy: King Radio establishes the original six “sonic laws” that still govern the medium today - Attention, Trust, Memory, Proximity, Monetization, and the Covenant (the promise not to abuse a listener’s time). Through a “Royal Council” of historians, strategists, and creators - including Kraig Kitchin, Cynthia Meyers, Tom Webster, Paul Riismandel, Arielle Nissenblatt, Shaun Michael Colón, and Dallas Taylor - the episode traces how radio evolved from scarce, centralized broadcast into today’s fragmented, platform-shaped attention economy.

Along the way, the story tracks the transfer of power: from advertisers who once owned the show, to broadcasters who later owned the minutes, to the reality that now rules everything audio and audio advertising - the audience owns the time. Podcasting rises as the rebellious prince built on abundance, intimacy, and active attention. But the same old risks return in new clothes: ad load inflation, disinvestment in voices, and platforms that reward behavior over craft.

The takeaway is both a warning and a blueprint for all audio advertising: the future belongs to the creators, brands, and networks that earn attention fast, protect trust, create memory, stay close to context, monetize without breaking the covenant - and keep building the lane instead of copying the last winner.

Industrial Musicals by Twenty Thousand Hertz

Monday, June 9, 2025 • Duration 31:46

Ever heard a Broadway ballad about bathroom fixtures? Or a devilish ditty about selling tires?

From the 1950s to the 1980s, America’s biggest brands—Ford, Xerox, American Standard—commissioned full-scale, professional musicals for their employees, not the public. These “industrial musicals” were staged at sales conventions, lavish one-night-only productions designed to inspire, educate, and entertain. And they worked.

In this special crossover episode, written & produced by Amelia Tait and Casey Emmerling, we hand the mic to the team at Twenty Thousand Hertz to explore this fascinating corner of audio history, led by comedy writer and collector Steve Young. You’ll hear unforgettable songs about silicones, diesel engines, bathroom bliss, and more—plus the human stories behind the people who created this unlikely art form.

It’s easy to laugh at singing salespeople, but it’s harder to dismiss how powerful these productions were. People remembered them. They were moved. They sold more because of them. The question isn’t, "Why they did it?" It's, "Why did we stopped?

Maybe it’s time to bring a little of that musical magic back to modern audio ads.

Antoniolytics™

Thursday, May 29, 2025 • Duration 42:22

In Season 3 Episode 7 of Ad Infinitum, Stew Redwine is joined by Antonio Coronado—aka Agent 004, aka Antoniolytics™—and together, they delve a critical point in the history of Audiolytics™ - the proprietary ad grading and devopment framework developed and used by OXFORd - the early days of human grading, and what happens when AI takes the wheel.

As the ad industry hits an inflection point—with AI tools being mandated at major platforms like Spotify—Antonio and Stew unpack what machines can do well, what they still miss, and where the soul of a great message resides. They discuss the importance of Audiolytics™ Key Components like Setup, Positioning, Substantiation, and that elusive “unifying principle” behind emotional resonance.

And, of course, Antoniolytics™ goes head-to-head with Audiolytics™, evaluating top ads from T-Mobile, BetterHelp, Toyota, and Mint Mobile to pit man against machine and find out if their grades are wildly different and who is the harsher critic, the one with or without a beating heart?

This episode is a time capsule, a tribute, and a turning point in the evolution of creative optimization, marking the end of the hand-graded era and the beginning of something new.

The Funny Thing About Audio Ads

Thursday, May 15, 2025 • Duration 46:35

Why does comedy work in audio ads—and why don’t more brands take the leap?

In Season 3 Episode 6 of Ad Infinitum, Stew Redwine is joined by improv legends Wayne Brady and Jonathan Mangum, co-hosts of Wayne Brady's What If?! with Jonathan Mangum, to explore the strategic (and often hilarious) role of humor in audio advertising. They unpack the data, riff on Stew's obsession with the comedic potential for life insurance ads, improvise jingles, and roast real radio spots from recent top spenders Progressive, Home Depot, Discover, and ZipRecruiter. Along the way, they reveal how brands can break out of the safety zone, find their comedic voice, and stand out in an AI-driven sea of sameness.

The Sound of Falling

Saturday, May 10, 2025 • Duration 06:04

In this brief bonus episode of Ad Infinitum, Stew Redwine shares a short audio story created for the Twenty Thousand Hertz “Sound Off” competition.

“The Sound of Falling” features original 1980s tape recordings of Stew’s grandfather, Herold Redwine, recounting his harrowing experience of being shot down in WWII, parachuting from a burning B-17, surviving as a prisoner of war in Stalag Luft VI, and enduring the brutal 68-day “Black March.” With audio production by Zach Hahn and sound design by John Mattaliano, the piece blends archival family audio and cinematic sound to capture the silence, fear, and resilience of a man who lived through the unimaginable.

Stew reflects on the power of preserving family stories and encourages listeners to do the same.

A.I. Slop

Tuesday, April 22, 2025 • Duration 49:47

In this episode of Ad Infinitum, host Stew Redwine is joined by commercial director Jordan Brady and Amplifi Media CEO and NYU professor Steven Goldstein to confront a fast-growing threat in the world of advertising: AI Slop.

Used by Steven in a blog post earlier this year, “AI Slop” refers to the dull, generic content flooding our feeds—fueled by AI tools used without intention or craft. This episode pulls back the curtain on how these tools are transforming creative work—for better and worse.

With the rise of “invisible minivans” (not Lamborghinis), Stew and his guests dig into how AI is flattening creativity, the steep cost of sounding like everyone else, and what marketers need to do to protect emotional resonance and brand authenticity in audio.

Stew, Jordan, and Steven put four of the top commercial radio ads through the Ad Infinitum wringer—grading each on persuasion, production, and sonic distinctiveness:

Progressive: A 10-second “riddle” spot that lacked flair and fell flat—proof that brevity doesn’t guarantee brilliance.
Verizon: A $50/month deal with an attempt at a clever hook (“cheaper than your dog’s glam squad”) and zero memorability.
AT&T: A 60-second travel-themed ad that waited 46 seconds to mention the brand. Result? $155K in wasted media dollars.
Cricket: The surprise winner. With early branding, relatable benefits, and lively sonic branding, it scored highest across the board—an example of simple, effective, human-sounding creative.

The verdict? You don’t need AI to sound robotic—humans are making boring, formulaic ads just fine on their own. But when brands fail to grab attention and stand out, they risk spending more for less impact.
