Doritos saw declining engagement with their core "Millennial" consumer group of teens and young adults aged 16-24. They developed a strategy called "The Big Idea" to put Millennials in control by encouraging user-generated content across digital platforms. This included online contests on blogs and websites to create Doritos commercials. The successful campaign led to increased sales, thousands of user entries and viral videos, and over a billion media impressions, re-engaging Doritos' core consumer group.
