The IAB Tech Lab released its Data Clean Room Standards portfolio. The first-of-their-kind guidance and resources aim to help "streamline audience activation by enabling interoperability between (clean room) vendors." The IAB also offered "a primer for clean rooms containing definitions, concepts, and a roadmap of future clean room proposals and initiatives" while presenting the new standards at its Building For Privacy Series. The new standards will be open for public comment through April 17. Editor's note: The IAPP's Joe Duball explored the privacy impacts stemming from increased use of clean rooms.
