The working group inside W3C where advertising use cases are represented in the web standards process. Privacy Sandbox proposals, including Topics API and Protected Audience, went through this group for review and comment before Google retired them in 2025\. The group is where publishers, advertisers, browsers, and privacy advocates formally disagree with each other before something becomes a standard. Following the group's output is how you stay ahead of what's coming to the browser, not just what Google is announcing.
