Reporters Without Borders

Reporters Without Borders (Reporter Sans Frontières, RSF) was founded in Montpellier (France) in 1985 by four journalists. It is is registered in France as a non-profit organization and has consultant status at the United Nations and UNESCO. RSF advocates for media freedom, supports independent media and protects endangered journalists worldwide. Its missions are

- To continuously monitor attacks on freedom of information worldwide;

- To denounce any such attacks in the media;

- To act in cooperation with governments to fight censorship and laws aimed at restricting freedom of information;

- To morally and financially assist persecuted journalists, as well as their families.

- To offer material assistance to war correspondents in order to enhance their safety.

Since 1994, the German section is active in Berlin. Although the German section works closely with the International Secretariat in Paris to research and evaluate media freedom worldwide, it is organizationally and financially independent. In that role, it has applied for a grant at the federal German Ministry for Economic Cooperation and Development – in order to finance the Media Ownership Monitor project.

Global Media Registry

The Global Media Registry (GMR) collects, compiles and provides – either publicly available or self-reported – datasets and contextual information on media outlets around the world.

In doing so, the objective is to enhance transparency, accountability and responsibility in the information space. Thus, the GMR facilitates better choices and decision making, both algorithmic and human, of all stakeholders. These may include every citizen and consumer, regulators and donors, as well as the private sector – for example advertisers and intermediaries (a. k. a. platforms and distributors).

By providing this public service as a social enterprise, the Global Media Registry contributes to the advancement of the freedoms of information and expression at large.

It was founded as a spin-off from the Media Ownership Monitor project, which it now operates as a non-for-profit LLC registered under German law.
