Google delays ending support for third-party cookies in Chrome to 2023

Today, we’re sharing the latest on the Privacy Sandbox initiative including a timeline for Chrome’s plan to phase out support for third-party cookies. While there’s considerable progress with this initiative, it’s become clear that more time is needed across the ecosystem to get this right.


We plan to continue to work with the web community to create more private approaches to key areas, including ad measurement, delivering relevant ads and content, and fraud detection. Today, Chrome and others have offered more than 30 proposals, and four of those proposals are available in origin trials. For Chrome, specifically, our goal is to have the key technologies deployed by late 2022 for the developer community to start adopting them. Subject to our engagement with the United Kingdom’s Competition and Markets Authority (CMA) and in line with the commitments we have offered, Chrome could then phase out third-party cookies over a three month period, starting in mid-2023 and ending in late 2023.

Chrome is, for some reason, the most popular browser in the world, and it sucks that Google has to delay ending support for third-party cookies. This is the price they pay for being as big and powerful as they are, since while cutting off third-party cookies won’t harm Google’s advertising business all that much, it certainly will harm the very few remaining competitors it still has. I won’t shed a single tear for any online advertising company, but I will shed a tear for the masses who still believe they’re hogtied by Chrome.
