Big: Google will stop using tracking technologies that identify web users as they move from site to site across the internet. The move could reshape the digital advertising industry. https://t.co/j24h5EDG2B

Online ads ecosystem is seeing an erosion of trust. So, to preserve the open Web while making it more private - Google won’t build identifiers that track users across the web. Read more on our blog https://t.co/Y1e7uaVTIP

1: inevitable and already happening, so get ahead of the story. 2: regulation is good for incumbents. Who loses most if we only target on 1st party data? https://t.co/r6dMZaI5OV

Good, but don’t skip over this sentence: “Google will still use first-party data, or data it collects from users directly, to target ads on its own publishing platforms, like YouTube.” https://t.co/hpfu3rmqwU

— Rob Pegoraro (@robpegoraro) March 3, 2021

Policymakers seriously ask us - why shouldnt we just ban targeted advertising? Industry has a narrow window to show ads can be customized while respecting data protection norms. A US privacy law will help. https://t.co/18IfMGCfLJ

NEW: @Google says that after it phases out 3rd-party cookies, it won't introduce other forms of identifiers to track individuals as they browse across the web.

The ? crumbles. (Sorry someone had to.) 3rd party data had quite a run. 2 decades of fraud, clickbait, deception, real fake news, mass data abuse, triggered biggest boycott in human history (adblocking), passage of multiple state laws… https://t.co/NNiTctv8uF

This is significant bc Google committing to avoiding work-arounds (like a Unified ID) that would continue to do indiv tracking
