For example: in 2019, the Knight Foundation announced a $5 million investment to establish what became the University of Washington Center for an Informed Public (CIP). The Knight Foundation also supported the Stanford Internet Observatory (SIO).
In 2020, SIO and CIP ran the Election Integrity Partnership, flagging election-related posts to platforms for censorship. In 2021, they launched the Virality Project to identify Covid-19 vaccine-related content for removal.
