Swiss media companies focus on joint advertising ecosystem: expansion of OneID and OneDSP continues
The Swiss media alliance OneLog is refocusing its efforts and strengthening its shared advertising ecosystem. The leading Swiss media companies TX Group, Ringier, NZZ, and CH Media are reaffirming their commitment to collaboration and are jointly investing in the expansion of the core components: OneID (an ID solution for digital advertising), OneDSP (Demand Side Platform, a platform for the automated purchase of ad space), and OneDMP (Data Management Platform, a platform for managing and analyzing user data).
At the heart of this strategy is the further development of OneDSP, the booking platform for digital advertising in Switzerland launched in September 2025. OneDSP gives advertisers efficient, data protection-compliant and overlap-free access to the premium inventory of the largest Swiss publishers - CH Media, NZZ, Ringier and TX Group - centrally, transparently and independently of international tech platforms.
The expansion of OneID will also be further accelerated in order to increase reach and integrate additional high-quality websites. The aim is to provide the total reach of over 3 million users on the advertising inventory of CH Media, NZZ, Ringier and TX Group as well as other publishers that are integrated via their marketers. Integration into the transparency and consent framework of IAB Europe ensures compliance with modern data protection standards.
With their joint advertising ecosystem, the partners are prioritizing a solution that gives advertisers simple, efficient and privacy-compliant access to premium inventory across all major Swiss media companies. At the same time, the initiative takes readers' concerns for greater data protection and transparency seriously and places them at the heart of the solution.
Instead of the originally planned joint login model (OneLog), the media companies are now focusing consistently on building this strong, independent advertising ecosystem.
As part of the strategic realignment, the Board of Directors of OneLog AG will also be reconstituted in October 2025. The composition of the Board of Directors reflects the partnership between the media companies involved: Ringier is represented by Dr. Patrick Rademacher (Chief Strategy & Innovation Officer, member of the Management Board of Ringier Media Switzerland) and Dr. Markus Wirth (Chief Operating Officer (COO), member of the Management Board of Ringier Media Switzerland from autumn). Dr. Markus Wirth will remain Chairman of the Board of Directors of OneLog AG. Thomas Spiegel (CEO Goldbach Digital) and Dr. Tanja zu Waldeck (Chief Operating Officer TX Group) will represent the TX Group. CH Media will be represented by Thomas Wegmann (Head of Publishing, member of the CH Media Executive Board) and NZZ by Remo Baumeler (CEO of audienzz).
Allianz sees this realignment as an important step towards strengthening the competitiveness of the Swiss advertising market.
