Iran's animation industry began by the 1950s, and was followed by the establishment of the influential Institute for the Intellectual Development of Children and Young Adults in January 1965. The 1960s was a significant decade for Iranian cinema, with 25 commercial films produced annually on average throughout the early 60s, increasing to 65 by the end of the decade. The majority of the production focused on melodrama and thrillers. With the screening of the films ''Qeysar'' and ''The Cow'', directed by Masoud Kimiai and Dariush Mehrjui respectively in 1969, alternative films set out to establish their status in the film industry and Bahram Beyzai's ''Downpour'' and Nasser Taghvai's ''Tranquility in the Presence of Others'' followed soon. Attempts to organize a film festival, which had begun in 1954 within the framework of the Golrizan Festival, resulted in the festival of Sepas in 1969. The endeavors also resulted in the formation of the Tehran's World Film Festival in 1973.
