The Platform Governance Archive (PGA) is a data repository and platform that collects and curates policies of major social media platforms in a long-term perspective. We have collected and curated different datasets that reach back into the founding years of major social media platforms in the 2000s.

The PGA is hosted by the Lab Platform Governance, Media, and Technology at the Centre for Media, Communication and Information Research (ZeMKI), University of Bremen. We operate the project in close collaboration with Open Terms Archive.
We also partner with the Alexander von Humboldt Institute for Internet and Society (HIIG) and the Centre for Media and Journalism Studies, University of Groningen in this project.
The PGA is operated out of the Platform Governance, Media, and Technology Lab at the Centre for Media, Communication and Information Research (ZeMKI), University of Bremen. We run the project with core university funding.
The PGA was a initially hosted and sustained by the Alexander von Humboldt Institute for Internet and Society (HIIG) that continues to be a partner of the project. The research and initial data collection has substantially benefited from funding by the European Union’s Horizon 2020 research and innovation programme as part of the ReCreating Europe consortium (Grant Agreement Number 870626). The Open Science Fellowship offered by Wikimedia Deutschland 2020 to João Carlos Magalhães was vital for the launch of the PGA by enabling concept building and data cleaning. Upon moving the project to Bremen, the Data Science Center at the University of Bremen generously provided a Seed Grant 2022 to further expand the dataset and to implement the collaboration with the Open Terms Archive and their technical pipeline.
