IREX’s Media Sustainability Index (MSI) provides in-depth analyses of the conditions for independent media in 80 countries across Africa, Europe, Eurasia, and the Middle East. Since the Eurasian MSI was first conceived in 2000, in cooperation with the United States Agency for International Development (USAID), the MSI has evolved into an important benchmark study to assess how media systems change over time and across borders. Since 2005, IREX has also produced an MSI for the Middle East and North Africa, with support from USAID, the US Department of State’s Middle East Policy Initiative, and UNESCO. In 2007 IREX launched the Africa MSI with funding from the Canadian International Development Agency, the World Bank Institute, and USAID.
