European television network. Headquartered in Amsterdam, Eurovision is Europe's largest broadcaster with 23 stations in 12 countries. The result of a series of mergers among regional broadcasters in the 1980's, the network has thrived under the current atmosphere of deregulation, expanding aggressively over the last ten years into the growing Eastern European market. Eurovision operates major studios in Amsterdam, London, Köln, and Paris, producing content in seven languages.
