    EUREKA, often abbreviated as "E!" or "Σ!", is a pan-European research and development funding and coordination organization. EUREKA aims to coordinate efforts of governments, research institutes and commercial companies concerning innovation. It does not partake in military research and follows a "bottom-up" approach to R&D funding, industry itself deciding which projects should be developed. As of July 2012, EUREKA has 41 full members, including the European Union. All 27 EU Member States are also members of EUREKA, with the last EU Member State, Bulgaria, joining in June 2010. EUREKA is not an EU research programme, but rather an inter-governmental initiative, of which the EU is a member. Cooperation and synergy are sought between EUREKA and the research activities of the EU proper, notably with European Union's Framework Programmes for Research and Technological Development and the European Research Area.
