Since the organisation of the first film festival in Venice in 1932 as part of the Biennale for Contemporary Art, a network of film festivals has spread from Europe – with Venice, Moscow, Cannes, Karlovy Vary, Locarno and later Berlin – all over the world.
It is estimated that the international market currently comprises around 10,000 film festivals. And while Kenneth Turan stated in his standard work Sundance to Sarajevo 15 years ago, „there is barely one day on the calendar where some film festival is not being celebrated in some exotic city somewhere in the world“, in October 2013 alone the association of Berlin film festivals advertised its platform berliner-filmfestivals.de with the slogan „Every day a festival day!„.
 1932 Mostra Internazionale del Cinema Venedig, 1935 Internationales Filmfestival Moskau, 1939/1946 Festival International du Film Cannes, 1946 Karlovy Vary International Film Festival, 1946 Festival Internazionale del film Locarno, 1951 Internationale Filmfestspiele Berlin (Berlinale).
 This figure is an estimate based on the Festival Directory (Filmfestival.com) with its 6,000 film festivals listed, as well as estimates by individual European film festival researchers, submission platform operators, submission agencies and world distributors.
