BACKGROUND:
Trusted sources of public health information and evidence-based communication tools are essential for practitioners and communities alike.(1) However, perceived overreach of industry and politicians shaping public health communication and policy erodes public trust; this distrust is amplified by disinformation and accelerated on social media.(2) In parallel, publicly owned media sources of vetted information are facing disinvestment.(3) In this context, the Communication Initiative (CI) platform is explored as a potential opportunity to rebuild and extend trustworthy public health knowledge, tools and networks.

METHODS:
This case study includes a historical reflection on a long-standing online platform (CI), with a network of over 50K members globally. Drawing on the web platform as a source of public record, key features that catapulted the CI from a site of knowledge dissemination to become a vast network where discussions and thought leadership were regular features are analysed. The case study also draws on contextual events and literature to present a trajectory for the current location of the CI and potential directions.

RESULTS:
The CI, founded in the late 1990s, has undergone a number of transitions, with its focus on transformative communication being a common thread. The upcoming transfer of the CI from ownership in Canada to a Global South partner is part of a long-standing vision accelerated by a series of dramatic events in 2025, including the founder’s death and funding cuts. Key lessons on partnerships, donor-dependencies, trust and ethics are described in relation to how they are shaping the platform’s evolution.

CONCLUSIONS:
The unique opportunity of the CI rests in an existing global network at a time that trust in Global North communication platforms are being questioned. The inclusion of both old and new partners in reshaping the platform is critical as a trust building exercise and to protect public health communication knowledge.
