Magnite-led consortium completes first phase of editor

LOS ANGELES, June 29, 2021 (GLOBE NEWSWIRE) — Magnite, the world’s largest independent sell-side advertising platform, today announced the completion of the first phase of a proprietary publisher segmentation initiative that addresses to the needs of buyers and sellers in a cookie-free environment. The initiative already handles more than three billion transactions a day and has more than 30 participants, including media owners and members of the buying community.

The first phase of this initiative aimed to help publishers define and assemble proprietary segments using existing industry standards from the IAB Tech Lab, establish a testing framework, and execute real-time trades against these vendor-defined audiences without using third-party cookies. .

The resulting Publisher First-Party Segments initiative presents publishers with an approach to addressability that offers both high accuracy and high scalability via federated segments.

Participants in this initiative include Adform, CafeMedia, Condé Nast, Future Publishing, Goodway Group, Havas, Hearst Magazines, IBM Watson Advertising, Insider, Maven, Meredith Corporation, Merkle|DWA, MiQ, News Corp, Permutive, Publishers Clearing House ( PCH), PubMatic, among others.

Bringing this initiative into Prebid is the right way to go – keep it open source and standard.

“As third-party cookies will fade from use in the near future, it’s critical the industry works to create publisher-controlled, privacy-preserving technologies,” said Paul Bannister, chief strategy officer at CafeMedia. “The First-Party Segments initiative is a fantastic step forward for cross-business collaboration and building a more sustainable future.”

Advertising. “These collaborations accelerate our opportunities for experimentation and learning, enabling the realization of next-generation solutions with enormous value. We look forward to continuing to strengthen this initiative with foundational ad-tech integrations.”

“Meredith believes the future of programmatic advertising lies in balancing the demands of advertising use cases and consumer privacy,” said Nicole Lesko, COO & Data Strategy at Meredith Corporation. “FPS leverages vendor-defined audiences to provide large-scale targeting to advertisers without the privacy concerns of deterministic identifiers in the auction stream.”

An industry-wide level of interoperability through sustainable and privacy-compliant practices is one of the primary ways to make this possible, so at MiQ we are excited to participate in these early tests and see the adoption of this solution. »
