antitrust authorities said earlier this year they are investigating whether the plan to remove third-party cookies from Chrome could hurt online ad competition. It's Chrome's goal to have technologies deployed by late 2022 for developers to start adopting them. The company said it continues to work with the web community on more private approaches to ad measurement, delivering relevant ads and content, and fraud detection. 'While there's considerable progress with this initiative, it's become clear that more time is needed across the ecosystem to get this right,' Vinay Goel, Director of Privacy Engineering at Chrome, wrote in a blog post. Google said last year it would end support for those cookies in Chrome by early 2022 once it figured out how to address the needs of users, publishers and advertisers and come up with tools to mitigate workarounds. They can be used to track users across multiple sites to target ads and see how they perform.

Cookies are small pieces of code that websites deliver to a visitor's browser and stick around as the person visits other sites.
