Growing out of the Somali people's rich storytelling tradition, the first few feature-length Somali films and cinematic festivals emerged in the early 1960s, immediately after independence. Following the creation of the Somali Film Agency (SFA) regulatory body in 1975, the local film scene began to expand rapidly. The Somali filmmaker Ali Said Hassan concurrently served as the SFA's representative in Rome. In the 1970s and early 1980s, popular musicals known as riwaayado were the main driving force behind the Somali movie industry. Epic and period films as well as international co-productions followed suit, facilitated by the proliferation of video technology and national television networks. Said Salah Ahmed during this period directed his first feature film, The Somali Darwish (The Somalia Dervishes), devoted to the Dervish State. In the 1990s and 2000s, a new wave of more entertainment-oriented movies emerged. Referred to as Somaliwood, this upstart, youth-based cinematic movement has energized the Somali film industry and in the process introduced innovative storylines, marketing strategies and production techniques. The young directors Abdisalam Aato of Olol Films and Abdi Malik Isak are at the forefront of this quiet revolution.
