Hear My Insights

Capturing Attention in the Age of AI

In a world saturated with content and shaped by algorithms, Kantar will explore how brands can capture and sustain attention. Our talk will focus on three key areas: the impact of AI on creative effectiveness, the shift from human-to-human to machine-to-machine-to-human attention flows, and the power of physical and sensory brand experiences. Through data and real-world examples, we’ll question whether AI is a threat to differentiation,or a lever for it—and ask: is the real battle still for attention, or already for recommendation?
