This is the best summary I could come up with:

Unlike the glitzy front-page Google blog post that the redesign got, the big ad platform launch announcement is tucked away on the privacysandbox.com page.

The blog post says the ad platform is hitting “general availability” today, meaning it has rolled out to most Chrome users.

This has been a long time coming, with the APIs rolling out about a month ago and a million incremental steps in the beta and dev builds, but now the deed is finally done.

Users should see a pop-up when they start up Chrome soon, informing them that an “ad privacy” feature has been rolled out to them and enabled.

That’s actually what started this whole process: Apple dealt a giant blow to Google’s core revenue stream when it blocked third-party cookies in Safari in 2020.

Google says it will block third-party cookies in the second half of 2024—presumably after it makes sure the “Privacy Sandbox” will allow it to keep its profits up.
