Live from Advertising Week NY 2025! Brian O’Kelley, Co-Founder & CEO of Scope3, explains how AI agents are about to transform media buying with a simpler approach that cuts carbon emissions by 99%. Instead of auctioning every ad thousands of times in real-time, the new system lets advertisers buy audiences and outcomes directly—making it easier for everyone while using dramatically less energy. Within two years, “programmatic” will sound as outdated as dial-up internet, and publishers will finally have the power to showcase their real value again.
