Mediendatenbank (mediadb.eu) is a prominent research tool launched in 2007 by the Institute for Media and Communication Policy (IfM), aimed at exploring the dynamics of the global media landscape. This innovative platform provides comprehensive insights into the media and communications industry, particularly focusing on Germany's position within the international arena.

Mediadatenbank not only tracks concentration trends and technological advancements but also presents various regulatory models from both domestic and international perspectives. A standout feature of mediadb.eu is its meticulous annual ranking of the world's largest media corporations, offering a unique overview of industry leaders.

Additionally, the database seeks to make the media landscapes of all 27 EU member states accessible to a broader audience, beyond just academia. The initiative is supported by the Federal Agency for Civic Education in Germany, making valuable information about media trends and market dynamics accessible to both researchers and the interested public alike.
