The Eurovision Song Contest (French: Concours Eurovision de la chanson), often known simply as Eurovision, is an international song competition organised annually by the European Broadcasting Union (EBU) among its members. Each participating broadcaster submits an original song representing its country to be performed and broadcast live to all of them via the Eurovision and Euroradio networks, and then casts votes for the other countries' songs to determine a winner. The contest was inspired by and based on the Italian Sanremo Music Festival, held in the Italian Riviera since 1951.
