Google’s Privacy Sandbox aims to replace third-party cookies with a more privacy-conscious approach, allowing users to manage their interests and group them based on similar browsing patterns. This is a major change for the online advertising industry, and after years of discussions and various experiments, it is about to become a reality for the online advertising industry. Starting in early 2024, Google plans to move 1% of Chrome users to the Privacy Sandbox and disable third-party cookies for them, the company announced today. Google’s plan to completely eliminate third-party cookies by the second half of 2024 remains on track.

Additionally, with the release of Chrome 115 in July, Google is making the Privacy Sandbox relevance and measurement APIs generally available to all Chrome users, making it easier for developers to test these APIs with live traffic. Google does not plan to make any significant changes to the API after this release.
Removing third-party cookies for 1% of Chrome users may not seem like it will have much of an impact, but as Google's Victor Wong, who is the product lead for private advertising technology within the Privacy Sandbox, said, it will help developers assess their real-world readiness for the bigger changes coming in late 2024. To prepare for this, developers will be able to simulate their readiness for the removal of third-party cookies starting in Q4 2023 and will be able to test their solutions by moving an adjustable percentage of their users into the Privacy Sandbox.

With the release of Chrome 115, most adtech developers will be able to start testing their solutions at scale. At that point, Privacy Sandbox features like Protected Audience, Attribution Reporting, and the Topics API will be locked down.
It's worth noting that today, users can already enable Privacy Sandbox testing in Chrome. The APIs have been available for testing since the launch of beta . However, this is obviously quite different from being able to test these APIs at scale.
Google's original plan called for the phasing out of tracking cookies as early as 2022, but the company changed that timeline in 2021 and then again in April 2022.

It’s no secret that Privacy Sandbox is not uncontroversial, and other browser makers take very different approaches to safeguarding their users ’ privacy . With the CMA closely monitoring Google’s initiative, the company has committed to a set of guidelines to ensure that there are no self-referential practices in its implementation of Privacy Sandbox that could give it an advantage over its competitors . With none of the competitors seeming particularly keen to adopt Privacy Sandbox, the implications for the overall online advertising ecosystem remain to be seen.
