The Columbia Institute for Tele-Information (CITI) is a university-based research center focusing on strategy, management, and policy issues in telecommunications, computing, and electronic mass media.

Founded in 1983 at Columbia University , the institute is the first research center for communications economics, management, and policy established at a US management school. Its location in New York City provides a unique foundation for these activities. Research collaboration among academic, corporate, and public sectors is vital in analyzing the complex problems associated with managing communications enterprises, systems, and policy in environments of rapidly changing technology and regulation.
