Zeta used Advertising Week New York to announce acquisitions of Senso and Digital Audience and unveil AthenaOS, while Digiday frames the wider shift toward "universal buying platforms" that Brian O'Kelley, now CEO of Apostra, argues combine intent, measurement and every ad surface: "Amazon is acknowledging that a programmatic-only DSP makes little sense outside a web-centric universe"; market caps now read AppLovin $93bn, Zeta $8.3bn, The Trade Desk $5.7bn and Magnite $3.6bn, with Apple's blocklist as the week's off-record anxiety.
