Some fingerprints fade, but others leave a lasting mark—especially in ad tech. The Rolling Stones warned us “you better watch out on your telephone” because someone’s always tracking. And in today’s digital world, that’s truer than ever. Google’s latest move to allow IP address targeting has everyone asking: is this smart marketing or just fingerprinting by another name? We’re breaking it down, plus covering the latest on TikTok’s potential ban, in-store media’s big moment, and the future of mobile monetization.
