QR Codes in Ads Called 'Stupid' as CTV Scan Rates Collapse
Andrew Tindall, a senior leader at System1, argues that QR codes in advertising are ineffective and harmful to brand building, citing new research showing CTV QR scan rates plummeting 60% between H1 2025 and Q4 2025 to just 0.004%. He references data from BrightLine, Innovid, TiVo, and LG Ad Solutions, which collectively show consumers largely ignore QR codes due to lack of interest. Tindall criticizes the industry's obsession with 'shoppable media' and immediate response, emphasizing that advertising's primary role is to build memory and future demand, drawing on research from WPP Media and Ehrenberg-Bass. He advocates for emotional, crafted ads without QR codes, citing works like 'The Long and the Short of It' and 'Lemon'.
- CTV QR scan rates in BrightLine's data fell 60% between H1 2025 and Q4 2025 to 0.004%.
- Innovid found only 200 QR scans per 1 million impressions.
- TiVo reported QR code scanning in TV ads fell from 30% in 2022 to 24% in 2024.

Cult Brand Building Key to D2C Coffee Survival
Sian Conway-Wood, who has worked with a D2C specialty coffee roastery, argues that the roast-of-the-month subscription model is flawed, promoting churn and failing to build lasting customer loyalty. She advocates for building a 'cult brand world' with consistent creative elements and content, rather than relying on rotating products and advertising. The case study shows that a tighter product range, a consistent brand narrative featuring 'tiny people' miniature models, and an active social media presence (around 60 posts a month) led to significant growth: subscription revenue grew 187%, organic social traffic up 274%, and direct traffic up 80%, with almost no paid media spend. The article emphasizes that for premium, intangible products like coffee, brand differentiation and pricing power are more critical than physical distribution or advertising spend.
- Subscription revenue grew 187% across the engagement.
- Organic social traffic increased by 274%.
- Direct traffic increased by 80%.
