As a lead sponsor of the event, Mastercard aimed to maximize brand visibility and ensure it was perceived as the most prominent and memorable sponsor among millions of international and local attendees.
The challenge was not only to achieve broad awareness, but also to connect with high-value audiences arriving in the city and convert exposure into measurable engagement.
Strategy
The campaign strategy focused on combining high-impact physical media with data-driven digital activation.
The objective was to:
• Reach international and domestic visitors in high-traffic locations
• Reinforce brand visibility through sequential messaging
• Connect offline exposure with measurable digital engagement
By integrating OOH visibility with mobile targeting, the campaign ensured that audiences who encountered Mastercard in the physical world could be re-engaged digitally.
Activation

OOH Presence
Strategic placements across key locations such as Istanbul Airport and major urban traffic corridors ensured maximum exposure during the event week.

This localized storytelling strengthened emotional engagement and connected the global football moment with a powerful local narrative.
