November 2025. The whole world was talking about the final season of the Stranger Things. And McDonald's, paid millions on licensing rights to ride the hype. However, Burger King is actually shown in the series without having paid anything. On Season 3, episode 6, minute 9. Just few hours after McDonald’s launched their ad campaign, Burger King announced the Whopper for just R$ 11 (ELEVEN reais), to anyone who posted the scene on social media. Yes, we turned the Burger King scene into a discount coupon — and instantly went viral. It hit so hard that McDonald’s asked Netflix to ask Burger King to shut the promo down. And that result proves the promo really worked. All the cupons were sold out in a matter of hours. With zero licensing fees, zero budget, zero media investment, we turned their multi-million-dollar investment upside down.
