In 1976 the World Festival of Animated Films in Zagreb  was not held because of the changes in the ASIFA festival calendar. When it was already agreed upon that festivals should take turns being held every third year respectively – Annecy, Mamaia, Zagreb – the organizers of Mamaia backed out at the last moment. Therefore in 1976 there was no world festival of animation under the auspices of ASIFA. From 1977 the two year schedule of international festivals was adopted again, and it started with Annecy.
