  • ‘New Coke’ and the marketing blunder of the century

    ‘New Coke’ and the marketing blunder of the century
    Aug 11 2025
    In 1985, Coca-Cola changed its flavour. You probably know that this was a complete failure. ‘New Coke’ was discontinued after just 79 days. But you probably don’t know the true reason why New Coke failed. Many claim it was due to poor market research, but today’s guest on Nudge, leading consumer behaviour expert Philip Graves, disagrees. Philip says New Coke failed not because the research was poor, but because market research is inherently flawed. Want to understand the biggest marketing blunder of the century?

  • Why naming a dish “field-grown” doubled sales

    Why naming a dish “field-grown” doubled sales
    Jul 21 2025
    How would you encourage sustainable behaviour? You might assume logical messages work best. Stuff like “the average three-hour flight creates ~250–400 kg of CO₂”. But today’s guest on Nudge has tested logical messages. And they don’t work. Today on Nudge, Toby Park from the Behavioural Insights Team explains how renaming a meat-free dish doubled its sales. Why targeting home-movers made Americans 400% more likely to cycle. How social norms can increase sales by 20%. And the reframing led the majority of Brits to choose energy-efficient fridges. --- Watch the bonus episode: https://nudge.kit.com/27720ca0ad Connect with Toby on LinkedIn: https://www.linkedin.com/in/toby-park-67773279/ Read Toby’s Net Zero Report: https://shorturl.at/Wy8RP How to Build a Net Zero Society: https://shorturl.at/0PcRk Sign up for my newsletter: https://www.nudgepodcast.com/mailing-list Connect on LinkedIn: https://www.linkedin.com/in/phill-agnew-22213187/ Watch Nudge on YouTube: https://www.youtube.com/@nudgepodcast/ --- Sources: Das, G., Spence, M.

    Super Mario Bros is 40 years old. It’s an incredibly simple game (it takes up the same memory as a smartphone wallpaper), yet it’s incredibly popular. Over 40 million people have played it. Why?
