How do you teach parents what children already know? ​

Marktplaats – Billy’s Marketplace

Challenge

For the third time in a row, Marktplaats developed a Toys campaign to persuade (grand)parents to consider buying and selling second-hand toys during the holiday season. Children already know that toys from another child are better, but why do parents still buy new toys every year?

What we did

TEAM LEWIS was involved all the way through the development of the 360 campaign, especially on narrative. We added an extensive PR layer to the media campaign, including a consumer survey, own platform data, influencers and the masterpiece: a children’s book. Usually, parents learn something to their kids through reading aloud but with this book we wanted parents to learn something from their children.

Why do we want to show you this?

TEAM LEWIS successfully worked within a multidisciplinary project team, where we advised on the narrative while staying focused on our objective: generating earned coverage.
