Sleeping Barber - A Marketing Podcast

Description
Picture a marketing world flipped upside down: Where heavy buyers aren't your golden goose, where loyalty programs might be missing the point, and where the brands you think are exceptional actually follow surprisingly predictable patterns. Dr. Nicole Hartnett, senior marketing scientist at the world-renowned Ehrenberg-Bass Institute, joins Marc and V to demolish some of marketing's most sacred assumptions with cold, hard data.
The Ehrenberg-Bass Institute is the world's largest centre for research into marketing and Dr. Nicole Hartnett has won the Market Research Society (MRS) Award for the best paper published by the International Journal of Market Research in 2022. Her groundbreaking research "When Brands Go Dark" analyzed 365 US brands from 22 consumer goods categories that stopped advertising for at least one year, revealing that brands experienced average sales declines of 16% after the first year, 25% after two years, and 36% after three years.
In this episode, you'll hear Nicole explain why most customer bases are dominated by light buyers who contribute roughly 40-50% of sales, how the Double Jeopardy law proves that big brands don't just have more customers but also slightly more loyal ones, and why mental and physical availability matter more than differentiation. She breaks down the difference between repertoire and subscription markets, reveals why advertising effects are "spread out really thinly over time" like "hitting them with a feather," and shares the surprising patterns that hold true across everything from coffee purchases to B2B software.
This isn't theoretical—it's the kind of evidence-based marketing science that's transformed how the world's biggest brands actually grow, backed by decades of empirical research that challenges everything you thought you knew about customer loyalty and brand building.

Description

Your media dashboard looks confident. Clicks up. Conversions tracked. Reach reported. But according to three years of evidence built on 1,265 global campaigns, that dashboard may be the single biggest obstacle standing between you and real business growth.

Andrew Tindall is Chief Growth Officer at System1 and the author of The Creative Dividend, a landmark publication built on the Effie Awards global case library representing $139 billion in market share. His finding is blunt: the more short-term digital metrics you chase, the less profit and market share you report. Not because measurement is the problem, but because marketers have been measuring the wrong things and the platforms selling those metrics have every incentive to keep it that way.

In this conversation, Marc and V dig into the data behind that claim: what Excess Share of Creativity (ESOC) actually measures and why it predicts profit growth exponentially, why all four dimensions of effective advertising: emotion, distinctiveness, showmanship, and consistency, are declining simultaneously, and why creator content outperformed TV as a builder of long-term brand demand in the research.

If you've ever sat in a room where the digital dashboard was treated as gospel and felt something was off — this episode is the evidence you were looking for.
