Enduring 'stay-up' brands don't need to fundamentally reinvent their core product. Instead, they should focus on creating opportunities for consumers to 'reappraise' the brand in a current context. The goal is to make the familiar feel fresh and relevant again, connecting it to modern culture.

To maintain cultural relevance, True Religion's CMO builds a diverse marketing team by hiring people from outside traditional corporate structures, such as the music industry. This ensures the team is genuinely tapped into emerging trends, a practice reinforced by weekly "tea time" meetings to share cultural observations.

Japan's manga industry's success stems from a deliberate strategy to stay focused on young readers. In contrast, the US comic market aged up with its audience, losing its pipeline of new fans and guaranteeing long-term decline. This applies to any industry.

"Culture" is often used too broadly. Brands should focus on "Little C" culture by tapping into existing pillars like music or sports. "Big C" culture—macro societal shifts—is a rare feat achievable only by platform-level brands like TikTok.

While Gen Z is overrepresented in ads, data shows that when they see themselves portrayed, ad effectiveness scores drop significantly. Common stereotypes of being tech-obsessed, awkward, or only in competitive situations alienate them. Intergenerational stories and portrayals of kindness perform better.

Chipotle's 'Behind the Foil' campaign was born from an internal memo asking employees to film videos about what they wished customers knew. The submissions became casting tapes, turning real staff into brand heroes. This approach provided unparalleled authenticity and celebrated the company's core operational strengths.

Modern marketing relevance requires moving beyond traditional demographic segments. The focus should be on real-time signals of customer intent, like clicks and searches. This reframes the customer from a static identity to a dynamic one, enabling more timely and relevant engagement.

Frito-Lay's Flamin' Hot brand moves beyond simple influencer marketing by studying and collaborating with obsessed subcultures. This approach informs not only marketing campaigns, like a song with Megan Thee Stallion, but also its core product innovation pipeline, making marketing a byproduct of deep cultural integration.

For specialized products, user motivation is more critical than age or location. Focusing on the user's mindset, life stage, and readiness for change (psychographics) can lead to significantly higher engagement and retention than targeting a broad demographic group that may not be ready for the solution.
