The new data shows OOH advertising delivers the strongest audience ROI across major media, with CPMs outperforming TV, print, and most digital channels on value.
It’s also effective. The research found OOH drives the highest consumer ad recall, across both printed and digital formats, beating out live and streaming TV, podcasts, radio, and online ads. The mix of efficiency and impact is why MAGNA projects OOH as the fastest-growing legacy medium in 2025.
