adtechEtymologyFrom ad + tech.nounDigital technology for the delivery and measurement of advertising campaigns.“Last week, Motherboard's Joseph Cox laid down $160 with Safegraph, a digital adtech/surveillance company, and got back the location trails of everyone who'd visited 600 Planned Parenthood locations. Safegraph claimed that this data was "anonymized." This is a lie. It's really, really easy to "re-identify" location data.”
