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.

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.

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.

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.

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.

This one’s for every Chief Audio Officer navigating the promise and peril of generative AI because making more ads faster doesn’t mean making better ads.

In this episode of Ad Infinitum, host Stew Redwine is joined by Eric Molinsky—journalist, audio producer, and host of Imaginary Worlds—to explore how advertising creates universes of its own through storytelling, sound design, and the audience’s imagination.

Ads aren’t just persuasive messages—they’re narrative constructs. Just like great novels or blockbuster movies, audio ads have the power to build immersive worlds. Whether it’s the cinematic lore of Apple, the absurdist multiverse of Geico, or the familiar nostalgia of Coca-Cola’s holiday canon, brands are world-building. The question is—how do they make it believable?

Drawing on his expertise from covering sci-fi, fantasy, and fictional world-building, Eric helps unpack how those same principles apply to advertising. From the “theater of the mind” that makes audio so immersive, to the use of recurring characters, in-world logic, and even breaking the fourth wall—this conversation offers a crash course in ad storytelling for every creative and Chief Audio Officer looking to level up.

Then, in true Ad Infinitum fashion, Stew and Eric analyze real podcast ads from Rocket Money, Capital One, USAA, American Express, and Bank of America, as tracked by Magellan AI. How well do they construct imaginary worlds—and where do they fall short?

You’ll hear:
 🌍 Why audio ads are the ultimate world-building medium
 🧠 How fiction techniques help audiences suspend disbelief
 🎭 When to break the fourth wall—and when not to
 🛠️ What ads get wrong about storytelling (and how to fix it)

Whether you’re a marketer, a writer, or a brand trying to make a mark—this episode will reframe how you think about advertising. Because the best ads don’t just sell. They transport.

In Ad Infinitum Season 3, Episode 3 - "Sonic Justice," Stew Redwine is joined by legal entrepreneur, founder of 1-800-NOCUFFS, and audio ad icon Darren Kavinoky to explore how bold, memorable local radio spots can deliver attention, affinity, and action in a sea of sameness from many Brand (bland) advertisers.

We can all recite the jingles and often preposterous intonations and taglines of local radio advertisers. They are founders and small business owners like Darren who have to lay it all on the line to make their audio ads work. If things don't work out, they're letting people go and possibly going out of business. So they play to win.

From humble beginnings and business-card ads in Russian newspapers to building one of California’s most recognized legal brands through the airwaves, Darren’s story is a crash course in founder-led audio success. Together, he and Stew break down why playing it safe is the real risk, how to build trust with sonic branding, and the five-pillar mindset that helped Darren grow from solo practitioner to multimillion-dollar firm.

You’ll hear:
 ⚖️ How 1-800-NO-CUFFS became a household name
 🎙️ The formula behind his unforgettable radio spots
 🔊 Why audio ad success is all about playing offense
 💡 And, how Darren dialed in his audio campaigns to convey empathy, ethos, and expertise—in just 15 seconds

This one’s for the audio rebels, the founder-CEOs, and every CAO ready to trade boring for bold and reap the rewards.
