Some of our most cherished beliefs started as ads. - 24 July 2026
This week's thread
We tend to think of marketing as a cultural mirror. But sometimes it's the other way round.
This is the idea of Culture Shaped by Marketing: that brands can invent rituals, phrases, and beliefs that outlive their original campaigns. These ideas become so ingrained in our collective consciousness we forget where they came from. They stop feeling like marketing and start feeling like truth.
In a world where merely getting attention is considered a success, surely transforming culture is the pinnacle for marketers?
This week's concept
Culture shaped by marketing
Brands largely fail to tap into culture - but a rare few shape it forever.
Thread ONE
Diamond wedding rings
The tradition of diamond engagement rings feels ancient and unbreakable. Yet just before World War Two, only 10% of American engagement rings had diamonds. A decades-long campaign by De Beers, famously linking diamonds with forever, single-handedly invented the modern ritual.
Why it matters
Invent a new ritual for your category instead of just a new ad (alcohol brands do this well).
Thread TWO
"Breakfast is the most important meal"
The idea that breakfast is the most important meal of the day is accepted as nutritional gospel. In fact, it was born from a 1944 radio campaign for Grape Nuts cereal. The slogan 'Eat a Good Breakfast, Do a Better Job' was created by marketers, not doctors, to shift more product.
Why it matters
Frame your product's benefit as a piece of universal, uncontested wisdom.
Thread THREE
Carbon footprint
We talk about our personal 'carbon footprint' as if it's a scientific, objective measure. The term was actually popularised by a 2005 BP public relations campaign. This clever reframing shifted the focus of climate change from industrial polluters to individual consumer choices.
Why it matters
Introduce a new piece of language that reframes the problem in your favour - but make sure it's morally sound!
The thread, pulled tight
The biggest win isn't a sale, it's an accepted truth. When marketing successfully shapes culture, it builds an unassailable competitive advantage. The brand becomes the author of the category's story, not just another character in it. This is the ultimate power of Culture Shaped by Marketing.

Rudolph the Reindeer
Even secular Christmas traditions aren't safe. Rudolph the Red-Nosed Reindeer was created in 1939 by department store Montgomery Ward as a character for a promotional colouring book.
