OSF-SA has long supported the use of film to communicate public information and to promote openness and accountability. This includes screening documentaries banned by the state broadcaster about Presidents, Marikana and other events in post-apartheid South Africa in local communities.
In 2017, the Open Society Foundations in partnership with Omidyar Network and the Media Development Investment Fund (MDIF) established the South African Media Innovation Program (SAMIP).
Since 2014, OSF-SA has supported organisations that aim to uncover injustices committed by the apartheid government and the private sector in South Africa to hold all forms of power to account.
In 2014, OSF with Atlantic Philanthropies and the Ford Foundation set up a special 10 year fund to advance constitutionalism in South Africa. The Constitutionalism Fund focuses on providing multi-year core and specialist support to organisations in civil society, through selection by a Local Panel, headed by Justice Yvonne Mokgoro.
In 2013, OSF-SA partnered with the Mail & Guardian Newspaper to set up new in-house Centre for Investigative Journalism (amaBhungane) – to develop investigative journalism work that was rooted in the public interest.
When the South African Government proposed introducing the Protection of Information Bill (commonly called the Secrecy Bill) in 2011 in partnership with the Open Society Justice Initiative, OSF-SA supported the launch of the Right2Know Campaign – now a coalition of thousands of individuals and at least 400 civil society organisations
OSF-SA provided extensive support to expand the Community Radio sector in South Africa, by supporting over 60 community radio stations between the period 1994 and 2003 to expand information access to millions of households across the country.
